Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day.
We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control (https://delta.dev/) that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

To apply, email harsh@thankly.ai with your GitHub or portfolio and one sentence about the best thing you've built.
Simple Analytics | DevOps Engineer | REMOTE (worldwide, any timezone) | Full-time, 32h, 24h possible | €5,000/month (full-time) | https://www.simpleanalytics.com/jobs/devops
Hi HN, I'm Adriaan. Simple Analytics exists thanks to HN: it started with my Show HN in 2018 [1]. Today we're a self-funded, profitable team of four building privacy-first analytics.
Privacy is why we run our own bare-metal servers instead of the cloud. We're preparing for a LOT more traffic, and you'll own the infrastructure and its reliability. We have good documentation. First project: leading the infra side of our Elasticsearch to ClickHouse migration, with Alex, our developer.
Stack: Ansible, OpenTofu, Docker Compose, Grafana, GitHub Actions, TypeScript. Clear async communication matters more than knowing every tool.
A tip for the upcoming ones: please tell us about yourself instead of repeating the job ad back to us. Leave your AI off for 10 minutes, and give us those spelling mistakes!
As feedback I just want to say, the salary feels low. I work in the Netherlands too and I think I’d have all your requirements. However, the job would be a big step down in salary - that’s also compared to similar roles I see around.
When you say "Full-time, 32h, 24h possible | €5,000/month (full-time)" is the €5,000/month salary pegged at 40h/week so that the actual payment is scaled up/down based on the number of hours worked per week?
Tether | Product Engineering Lead, Keet | REMOTE (Worldwide)
We're looking for a Product Engineering Lead to help build and scale Keet, a fully peer-to-peer messaging and video calling app.
You'll lead API and frontend engineering teams, working closely with Product to turn the roadmap into high-quality features.
We're looking for someone with:
- Experience leading engineering teams building consumer products.
- Strong JavaScript and React skills.
- Solid product sense and technical leadership.
- Understanding of distributed, local-first or P2P systems.
Apply: https://tether.recruitee.com/o/product-engineering-lead-keet...
Pond AI | Head of Engineering (founding-level) | San Francisco | Onsite | Full-time | https://joinpond.ai
Most non-tech businesses know exactly which workflows they want AI agents to handle, but have no one to build, connect and run them. Pond delivers custom AI agents to these businesses through a network of 7k AI builders, with Pond as the platform and security layer over MCP.
We're backed by Tier-1 VCs and a co-inventor of GPT, and we're looking for a hands-on technical leader to own the platform end to end.
You'd be a great fit if you:
- Build full-stack and ship AI agents in production (TypeScript/Python, LLMs, tool use)
- Have worked on payments, agent coordination/MCP, or platform/marketplace products
- Have early-stage startup experience (founder, founding or early engineer) and like to grind
Email dylan@joinpond.ai with something you've built.
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
We're rapidly scaling up operations - we're already hiring operators in the UK too - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!
Every prescription filled on a health plan gets priced and paid at the pharmacy counter in seconds, passing through four or five companies, and the employer paying for it almost never sees what it cost. We're building the platform those claims are priced, paid and audited on, in the open. TPAs and brokers build on it.
I'm the founder and an engineer, and I've written most of what exists. Hiring engineer #1. The problems: paying the same claim exactly once across reversals, rebills and retries; a versioned API that outside companies build their business on; isolating each customer's health data, enforced in Postgres; and drug prices that change retroactively but still have to be explainable. Stack: Python, TypeScript, Postgres, GCP. No healthcare experience needed.
Email me at hello@kanurra.com with something you built and the one thing in it you'd never let change.
Exponent | Lead Engineer, AI Accounting | New York (Flatiron) | HYBRID, 2+ days in office | $160k–$200k + equity | Full-time
Exponent is a financial platform for franchise and multi-location restaurant operators: charge cards, loans, and an AI-powered Accountant that pulls in an operator's POS, bank, payroll and processor data, reconciles it, and automates the monthly close.
You'd own core systems in the Accountant: idempotent ingestion from unreliable third-party APIs, the background jobs that keep thousands of accounts in sync, and the decisions about how LLM classification behaves inside a ledger that has to be right. Full stack, focused on backend architecture. Rails, Postgres, Sidekiq. We ship multiple times a day.
We want someone who ships fast and knows when to slow down. 5+ years, deep experience in any server-side framework (Rails, Django, Phoenix, TypeScript), and fluent with AI-assisted development. Fintech and Rails experience are strong pluses.
Email careers@exponentfi.com with a short note on why this interests you.

Encube | ML Engineer, ML Ops Engineer | Stockholm, Sweden | ONSITE | Full-time
Encube is a platform where hardware teams look at their 3D designs and engineering drawings together and make better products faster. We're building AI that understands those drawings and 3D models, and can eventually create them. Evaluations are a massive priority, and we need to consistently demonstrate how our models are better than frontier VLMs.
ML Engineer: train models that connect 2D drawings to 3D models, build agents that generate CAD and drawings, figure out how to measure if they're actually good, and ship them to real customers. PyTorch. Bonus if you've worked with 3D, CAD or graph neural nets.
ML Ops Engineer: on-prem and AWS GPUs, make every experiment reproducible, keep costs down and customer data safe, and get rid of whatever slows the ML team down. SkyPilot, MLflow, PyTorch.
Namespace | San Francisco, CA / New York, NY / Zurich, Switzerland / Remote | Full-time | REMOTE or HYBRID | https://namespace.so

Teams at SpaceXAI, Ramp, Sierra, Fal, Vanta, Framer, ElevenLabs, and many others build their software on Namespace today.
Open roles (all full-time, global, remote & hybrid):
Our roles are hybrid by default, based in the cities that correspond to our careers page listings. That said, we're open to and do hire people remotely as well if it's a strong fit, we don't want location to be the reason we miss great people!
We're building the world's first commercial stellarator fusion power plant. First spin-out from the Max Planck Institute for Plasma Physics, based on Wendelstein 7-X (the largest stellarator ever built), €650M+ raised, teams in Munich, Zurich and Oxford.
Finding a good stellarator design means searching an enormous high-dimensional space, and every candidate design needs heavy plasma physics simulation. That's the compute problem this role owns: cloud + HPC clusters, K8s, Ray, Dask, and the platform work around it (CI/CD, IaC, observability).
You'd sit directly next to the physicists and AI researchers burning through that compute, so you see exactly what your infrastructure unlocks. Python and Linux.
If you've wanted to point your platform engineering skills at something that actually matters, clean, abundant energy, this is about as direct a shot as it gets, and it's happening in Europe.
Interview process: recruiter call, meet the team lead, technical panel, meet the CEO.
Fully remote cloud & AI services company (founded 2015, 70+ engineers, AWS Premier, Google Cloud & Snowflake Partner) with a growing GenAI practice and several active client projects.
You'll build production LLM agents for clients: multi-agent systems, tool use and RAG, in Python, on AWS Bedrock and GCP Vertex AI. Direct client contact.
We're looking for a hands-on engineer (not a research or prompt-only role) who has built and shipped LLM agents to production, with frameworks like Strands Agents, LangChain, Agno, Deep Agents, Google ADK or Claude Agent SDK.
Just as important: we hire good people. Communicative, collaborative, eager to learn and happy to take ownership. That's what makes people succeed here, with clients and with the team.
IMC Trading | Machine Learning Engineer | Amsterdam OR London | ONSITE | Full-time
IMC is a research-driven trading firm and has been a market maker since 1989. Our researchers, traders and engineers work as one team on systems we build ourselves, trading across global markets.
We want ML engineers to shorten the path from a research idea to a live trading strategy. You’ll work with quant researchers, HPC specialists and software engineers in one of two overlapping areas:
- ML research engineering: distributed training pipelines, experiment automation, and making training faster and cheaper to run at scale.
- ML performance engineering: low-latency, real-time inference, and getting the most out of GPUs.
Stack includes: PyTorch, CUDA
We’re looking for 3+ years of hands-on ML systems work and production Python code you’ve owned over time. You should understand what happens beneath the high-level APIs and measure performance before you optimize. Depth in distributed training, GPU optimization, real-time inference or numerics at scale is a big plus.

We're looking for Senior Product Engineers who like owning ambiguous problems end-to-end. No perfectly shaped tickets. You talk to customers, understand messy workflows, make product decisions, ship, and own whether it actually works.
The problems we care about:
- How do you make a 380M-profile dataset feel fast, trustworthy, and easy to explore?
- How do you turn chaotic influencer marketing workflows into product that feels obvious?
- How do you build tools that work for both small teams and brands like Stanley, Sennheiser, Birkenstock, and NordVPN??
We're around 90 people, raised an €11M Series A, and ARR is doubling every year. HQ is in Tallinn, engineering is fully remote across Europe.
No ticket factory. No seven layers of approval. Small teams, real ownership, hard product problems.

Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed, https://github.com/mastra-ai/mastra
Why: Four months ago Mastra was a very popular open-source agent framework with very little monetization. Then we launched our platform, and now we're closing a couple of deals a week. Pipeline is growing faster than one person can work it, so this is our second dedicated sales hire. You start day 1 with a warm pipe: most leads are already using the open-source framework.
What you'd sell: Platform (Studio, Server, infra to run/debug/observe agents in production, hosted or self-hosted for regulated orgs), Agent Builder (agents without code), and Concierge (embedded Mastra engineers working alongside customer teams). Full-cycle, mid-market: Series A–C, often with regulatory or infra constraints, sales cycles of a few weeks, talking to eng leaders.
You have: Closed full-cycle deals in dev tools, OSS, infra, or AI. Enough technical depth to come across as a smart PM with engineers: understand their use cases and scope a solution. Founder or founder mentality. Comfort with a product that ships something new every week.

UNICEF - REMOTE backend dev - Digital Inclusion Division, Connectivity Credits
We're building a marketplace where local ISPs connect schools and health centers to the internet, prove it via telemetry, and get access to discounted backhaul, IP transit and compute from large infracos.
Currently in pilots in Mexico, Kenya, South Africa, Malawi.
Looking for 1 dev to join a small tech team (3 people) working on this protocol and marketplace, which sits on top of a larger tech team of 30 people at UNICEF Digital Inclusion. Not your typical UN job or culture.
If you want real talent, consider lowering the barrier to entry by not having people have to add in their work experience, education, and fill out a DOCX in addition to everything else.
Thank you for sharing this role. Blockchain for an ISP marketplace makes a lot of sense, especially in a humanitarian context where tech sovereignty matters. I'll definitely be applying!
NEO Holdings (stealth, regulated commodity markets infrastructure) | Malibu, CA | ONSITE (SoCal preferred) or REMOTE (US) | Full Time
We are a funded and backed venture building the regulated base layer for tokenized commodities including the US-regulated trading venue, Mint and benchmarks, bridging institutional commodity markets and on-chain finance. Commodity markets trade tens of trillions a year on infrastructure designed for paper-based trading; we are what comes next. Launching Q1 2027.
Roles currently available:
VP of Engineering: owns the platform end to end, from on-chain contracts (Avalanche) to the trading engine, custody integrations and institutional-grade security and operations. A VP or SVP who still builds and ships, not one who just manages others; you will have a real say in the architecture before we finalize it and will work with leaders in tech and commodities. You must have done this before: delivered a trading venue or institutional token issuance, end to end. $200K to $300K base plus equity depending on experience and location.
Lead Product Manager: works with our partners and customers to ensure the launch product suite is fit for purpose and aligns participant experience across onboarding, trading, collateral and reporting. You must have shipped products in a regulated financial venue, exchange, clearing house or institutional crypto platform, you write the spec yourself, and you have run product through a regulator's questions. $150K to $240K base plus equity.
We hire on written replies and quality of CVs. We read every reply ourselves, so please write yours yourself. Send a short note on what you have built that is closest to the seat, with references, to careers@neo.co and put the role in the subject line. Please mention you came from HN.

Memorang | Product Engineers + Technical Project Manager | Full-Time | Los Angeles (or US remote for exceptional hires)
Memorang is an "AI stack for education" that helps organizations build, launch, and monetize AI-powered learning and assessment products. Think Vercel plus Shopify for EdTech. We currently operate on an enterprise model, serving as the AI technology and commercial partner behind new product lines for organizations like ETS, McGraw-Hill, Pearson, and the ACT.
We’re hiring for two roles:
Product Engineers
Own features from the first rough idea to production. You’ll work across AI workflows, backend systems, and user interfaces, making product decisions along the way. We’re looking for engineers who ask good questions, care about the details users notice, and can turn an ambiguous problem into something useful and shipped.
Technical Project Manager
Turn complex work into clear plans and keep delivery moving. You’ll coordinate across engineering, design, and customer needs, surface dependencies early, resolve blockers, and keep owners and timelines clear as priorities change.
Ideal background: an engineer who moved into project management, with startup experience and enough technical depth to discuss APIs, architecture, and AI workflows with the people building them.
Why join?
A small team, meaningful ownership, and products used by millions. You’ll help shape what we build and how we work, with a short path from an idea to seeing it in users’ hands.
Remote-first, async-friendly, with health and wellness stipends, home-office support, and paid time off.
Apply: Email careers@memorang.com with your CV, a few sentences about what interests you, and something you’re proud to have built or delivered.
Quantum Rise | Chicago IL or Remote (US, Brazil or EU) | Full-time | No visa sponsorship | https://www.quantumrise.com/
Quantum Rise is an AI-forward consulting startup serving the mid-market in the US and larger enterprises in LATAM. We see companies in multiple industries struggling to understand how to leverage artificial intelligence in their day-to-day operations, trying to understand what their existing workforce now needs to know, or trying to understand whether they're about to be disrupted and need to change how their existing processes work. Many have business problems which "traditional" machine learning could help with even prior to the current GenAI hype cycle, but for whatever reason hadn't prioritized doing until now. Many have employees looking to incorporate agentic AI safely and effectively across different business areas. We try and help getting a handle around these issues and designing outcome-driven solutions.
Agentic AI Engineer: You'll work directly with clients to benchmark, train and deploy agentic systems for industry-specific problems. We're looking for someone deeply embedded in agentic engineering practice across vendors and platforms. Companies are looking for ways to leverage agentic systems to upskill their practitioners and need help navigating a new, powerful scary world.
AI Solutions Engineer: You're someone who has experience in traditional machine learning and data science applications in addition to more recent agentic systems.
We think of these two roles as complementary -- agentic AI solutioners help clients understand the forefront, whereas pure AI solutioners help them pick and build the right solution even if it isn't an LLM.
Both are front-facing development roles for someone who loves both tech and tackling real business problems. We love people with prior experience in multiple industries.
To apply, send me an email at julian.berman at quantumrise.com, mentioning HN and including your CV.

Taxnova | London | Hybrid
Founding product engineer
Taxnova (a16z Speedrun) builds AI that turns engineering data into tax and finance intelligence for teams like incident.io and Paddle.
We’re hiring a core founding engineer to work side by side with the CTO and own the AI product, roadmap input and client delivery.
FutureSearch builds AI that predicts the future. You can see our public track record on our site. We launched the FutureSearch product this August. We also publish benchmarks and datasets, and do work for frontier AI labs.
I'm the CEO, previously CTO of Metaculus and creator of Google's current internal prediction market. FutureSearch is about ten people, remote-first and concentrated in London.
We're hiring (US pay, adjusted to the local market elsewhere):
- Chief Operating Officer, $180–250k
- Director of Partnerships, $160–240k

Mesmer (YC P25) | Founding Engineer | Berlin | ONSITE | VISA + relocation | €100–140k + 0.5–1% equity
Mesmer builds software factories for engineering teams. Keeping a team at the state of the art with agents is a full-time job, so we do it for our customers: we're always finding the biggest bottleneck in how their team ships and fixing it in their factory.
As a founding engineer you'd do both halves. You'd work in customers' factories, at the frontier of how software gets built with agents, and you'd build the product that makes that work repeatable. We're seven people, repeat founders and CTOs, in one office in Berlin.
We're looking for senior engineers who use coding agents every day and have strong opinions about how the work around them should change.
About two weeks from first call to offer, no live coding or take-home. Email hiring@mesmer.co with a short intro and something you've built.
VALIS (Valis Insights) | Software Engineer, new product line | REMOTE (US, East Coast hours) | Full-time | $125k-$155k + equity
I'm Caleb, co-founder/CTO. VALIS builds data products for scrap metal recyclers. Our product images, weighs, and classifies scrap metal, and our platform turns that into actionable quality analytics to improve physical ops at plants across the US. Recycled metal takes a fraction of the energy of mined metal, and better data means more of it gets recovered.
We're hiring an engineer to build our next product line: a production tracking and analytics platform for recycling plants, extended from our existing product. We're a small team (<10 ppl). What you'd work on (ideate, build, deploy, own):
- Modeling a complex (and intellectually stimulating) physical process
- Agentic features that dig through production and quality data, surface trends, flag anomalies, and notify the right people
- Working directly with customers: regular calls with operators and plant managers, plus a few site visits a year
You should have 3+ YoE, strong data modeling fundamentals, and enjoy owning ambiguous problems end to end. We care more about how you think than what exactly you've used. Recycling, ERP/MES, or physical ops software experience is a plus.
TheraPlug | Founding CTO / Technical Lead | Detroit preferred; remote considered | Equity-first, pre-funding
I’m Marcelus Brice, founder of TheraPlug (https://theraplug.health). We’re building a behavioral health platform focused on making it easier for patients to find appropriate therapists and access care through insurance, starting in Detroit.
We’re looking for a hands-on technical leader who can build alongside a lean team and help recruit its founding engineers. You don’t need a previous CTO title, but you should have shipped and operated production software.
The product will support iOS, Android and responsive web, including:
• Patient and provider onboarding, scheduling and secure messaging.
• AI-assisted therapist matching based on clinical needs, preferences, insurance and availability.
• Provider credential verification and payer enrollment workflows.
• Insurance eligibility checks and estimated patient costs.
• Secure video sessions and clinician-reviewed AI documentation.
Relevant experience includes full-stack development, mobile apps, healthcare integrations, sensitive-data security and practical AI implementation. We value clear architecture, accessible design and thoughtful use of established services.
Compensation: We are pre-funding and cannot offer an immediate cash salary. We’re seeking someone interested in an equity-first founding role, with a planned transition to salary when funding supports payroll. Equity, responsibilities, time commitment and compensation triggers would be agreed in writing before work begins. Funding timing is not guaranteed.
To start a conversation, email marcelus@theraplug.health with:
• Products you’ve built and your specific contribution.
• Relevant healthcare, security or AI experience.
• Your location and realistic availability before funding.
• Your interest in leading and assembling a small development team.
I can share the detailed product scope and team requirements.

Mozilla's New Products group is a small team building new things on top of browser engine technology. We're hiring a hands-on, senior IC to run experiments inside browser engine internals and find out which ideas actually hold up.
What you'd do: design and build experiments in engine subsystems (DOM, layout, accessibility, JS runtime, networking), prototype features that let programs interact with web pages reliably, and measure everything. That means repeatable benchmarks, profiling overhead, and writing up the experiments that didn't work too. You'll use AI tools heavily, but you'll verify what they produce by testing and measuring it.
You likely have: deep experience in at least one browser subsystem, strong C++ or Rust, comfort in a very large codebase, a solid grasp of how the web platform behaves, and a real interest in AI agents and their tooling. Contributions to Gecko, Servo, Blink or WebKit are a big plus.

PO #HN-2611
Supplier: you
Line 1: Software Engineer qty 1
Line 2: Deployment Strategist qty 1
Need-by: yesterday
Status: AWAITING SUPPLIER ACK
Every hardware buyer knows this PO. It goes out, and then nothing happens: no ack, no ship date, just chasing over email while the spreadsheet and the ERP disagree. Silkline is the AI operating system for procurement at companies building satellites, launch vehicles, reactors, and robots (Machina Labs, Astranis, K2 Space, Castelion, Antares). We 5x'd our customer base, and our customers' parts can't wait.
- Deployment Strategist (new): own customers from signed contract to go-live. Map ERP/PLM/MES data into Silkline, write the SQL, and find out why the PO isn't syncing. Two paths in: ERP/MES implementer or forward-deployed engineer. 4+ years; travel to customer sites. https://jobs.gem.com/silkline
Both roles touch ITAR-controlled data: US persons only, no visa sponsorship. Small team, direct line to the founders (Isaac and me), plus a space-suited mascot named Silky.
Be the supplier who actually acks. Apply above, or email brent+hn@silkline.ai with "PO #HN-2611 ACK" in the subject (mention HN).
Curiosity (https://curiosity.ai) | Forward Deployed Engineer, DevOps Architect | Toulouse, France | ONSITE | Full-time (CDI) | Visa support
Curiosity Studio builds internal apps and agents from a plain description, on a company's connected data and inside its permissions. It runs on premises or in a private cloud, with any LLM. We're bootstrapped, profitable and based in Munich. Our customers are large industrial and regulated companies, Airbus among them, and Studio has 30TB+ of data connected in production.
We are starting a team in Toulouse that works at customer sites, in French and English, along with the engineers who build Studio.
Forward Deployed Engineer: take a customer's problem from the first workshop to production. You decide with them what Studio should build, connect their systems, model the data as a graph, and oversee the C#/.NET connectors and services it needs. You also ship features and agents on top.
DevOps Architect: Own deployments in customer environments, from the first technical discussion to handover, on private clouds or data centers. Networking, IAM, Linux, Docker, monitoring, backups, upgrades, incidents. You also write code alongside the forward deployed engineers.
We're looking for hands-on builders who enjoy working directly with customers. Full-stack project experience preferred. Fluent French and English required.
Interviews: a 30 minute call, a technical conversation, then the founders.
Datadog is a monitoring, tracing, logs system, and more, for your infrastructure and services. We build our own tsdb, event store [1][2], distributed tracing tools, cutting edge visualizations, and more. We love shipping great experiences for customers just like us and are growing fast!

Juro | AI Engineer (Agentic team) | London, UK | REMOTE (UK) | Full-time | £115k + equity
Juro is an AI contract automation platform used by in-house legal and business teams. Our Agentic team builds Operator, the agent that works across contracts inside Juro: it answers questions and takes action on legal data. You'd build the tools that let it act across the product, own parts of the agent harness (planning, tool use, context) and put evals around what you ship, together with our QA team.
Stack: TypeScript/Node.js, MongoDB, pgvector, AWS Bedrock, LiteLLM, Mastra, some React. Engineers pick their own AI tooling (Claude Code, Codex, Cursor...) and we pay for the usage.
We're looking for programmers first who now build with LLMs, and who have shipped something people use. Years of ML matter less to us than what you've built. We apply models, we don't train them.
Process: 30-min intro call, interview with the hiring manager, a build review where you walk us through something you've built, and a short chat with our CTO. We reply to every applicant.
You'll work from the UK. For exceptional candidates we can sponsor a UK Skilled Worker visa, whether you're relocating or already in the UK. If you need sponsorship, say so in your application.

As our GTM engineer you'll build the analytics, attribution and automation behind growth: which launch, post or creator actually brings people in, and the workflows that run the funnel without manual work. You'll work alongside our founding growth lead, who owns the channels and the story while you make sure every bet can be seen and measured. You can build in code, you care about clean data, and you'd rather automate a task than repeat it.

Jump | Founding Engineers (Software/AI, Manufacturing) + all roles | Miami, FL | REMOTE (US) until Jan 2027, then ONSITE | Full-time | $140K–$160K + equity | No visa sponsorship | https://jumpscientific.com/careers
Ethan here, founder of Jump.
Machine shops lose jobs because quoting is slow. A part comes in, someone has to read the drawing, figure out how to make it, and price it, and that can take hours. Many shops also can't put customer drawings in the cloud (ITAR, export control, or just customers who say no).
We're building Jump Quote: AI that reads a shop's drawings and drafts quotes in minutes, running on the shop's own computer. We're starting with a small group of founding CNC shops. Long term, we want anyone to be able to make anything, anywhere.
We're hiring founding engineers first (software/AI and manufacturing), but every role is open. If you're exceptional at something a startup needs, apply.
We care about kindness, honesty, ambition and intelligence. We don't care where you went to school or who you've worked for. We care that you have a winning mindset and can learn and ship fast.
How it works: we start now, remote within the US. In January 2027 we're together in person in Miami, and that's when the $140K–$160K + equity package starts. You need to be authorized to work in the US for at least the next 3 years; we can't sponsor visas.

Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.
We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!
We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.
You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows.

University of Cambridge, University of Manchester | PhD in AI / Earth Observation / Environmental Science | ONSITE | UK home fee status only | £30k tax-free annual stipend
Our group at Cambridge works on Earth Observation foundation models (Tessera: v1 https://arxiv.org/abs/2506.20380, v2 https://arxiv.org/abs/2607.03949, https://geotessera.org/) and we've started a collaboration with Manchester to understand how they can be used to improve pollution models and then environmental decision making in general. This involves training new models and doing high-resolution inference across national or even global scales, as well as figuring out how to use that data to help policymakers make better decisions.
As part of this work we have a PhD studentship through the joint Manchester-Cambridge Centre for Doctoral Training for AI in Decision Making for Complex Systems. This involves one year at Manchester doing taught postgraduate study and then three years at Cambridge for the PhD.
Our work is all open source and involves solving significant compute and data challenges. Training our current-generation model takes ~250k GPU hours and a single year of global inference needs to move over 5.5 petabytes of data through the inference pipeline. This project would suit someone with strong machine learning and software engineering experience. We can help you build the atmospheric science and Earth Observation skills.
We are a highly collaborative group who spend our time not only on foundational research but also on developing applications with practitioners and decision makers. Our work sees use in many industrial, academic and government environments for problems like crop classification, tree species mapping and change detection.
You can find out more here: https://www.findaphd.com/phds/project/from-satellite-to-stre... - if you have questions about the project you can contact me, Sadiq Jaffer, at sj514@cam.ac.uk . For questions about the application process you'll want aidecisionscdt@manchester.ac.uk .

Our tech stack is Typescript, React, Next.js and Tailwind. On the backend we use Drizzle with Neon, deployed and monitored via Vercel. Agents and background jobs are executed via trigger.dev. This gives us a killer DX because the entire tech stack supports preview branching. This allows coding agents to work in parallel on different features and verify their work independently very close to what will run in prod. CI is fast (2-3 min) and coverage is good enough to deploy to prod many times per day.
Please note that we are working remotely in the CET timezone. Having some remote experience is a plus.
We have pre-seed funding from a major US VC and are experienced founders. You’ll be working alongside the founders (ex-Apple, ex-Airbnb, ex-Tulip, ex-Tourlane) and will have a chance to shape the company, product and of course the engineering culture.
humans& | Product Engineer (Member of Technical Staff) | San Francisco | ONSITE | Full-time
humans& is a human-centric frontier AI lab. Our view is that AI should help people work together, so it has to understand people and the relationships between them, not just tasks.
Last month we launched Boba (https://boba.app), an assistant you can text one-on-one or add to a group chat. It runs on Ampersand, our first model, trained with RL over millions of simulated days with thousands of simulated people. Boba keeps track of your goals for weeks or months, sets up reminders and calendar invites, uses email and searches the web. In a group chat it reads social context and decides when to speak up and when to stay quiet. Early users have sent it more than a million messages.
Looking for product engineers who have done exceptional work on how humans and computers interact. You’ll build the product side of this: new interaction patterns for an AI that lives in group chats, remembers people and acts for them.
The founding team comes from xAI, Google DeepMind, OpenAI, Stanford and MIT. Our investors include NVIDIA, GV and SV Angel.
We build AI agents that run revenue for short-term rental and hotel operators on Booking.com and Airbnb: live prices, promotions and visibility on real portfolios, plus an MCP connector so customers work their accounts from Claude and ChatGPT.
Our engineers no longer type most of the code. Claude Code and Codex do. The hard part is knowing what to build, how it should fit together, and whether what the agent wrote is actually right. You will talk to customers, own the architecture, write the briefs, and catch what the agent missed.
We do not care which language you know.
We care that you can do architecture (single source of truth, clear boundaries, the right layer for a fix) and that you already ship this way.
Big bonus if you have worked on hotels, short-term rentals or dynamic pricing.
Small team, paying customers, hard problems (private OTA APIs, PMS integrations, pricing decisions that move real money). Three interview stages, no take-home. Email me (CTO) directly: martin@mydatavalue.com

To apply, please contact jobs@sendery.co (we don't respond to other email addresses for job postings) with your resume and github.
Middesk helps companies figure out who’s actually behind a business. Banks, fintechs, and platforms rely on us to get that answer fast and accurate before they issue a card, fund a merchant, or open an account.
We pull data from hundreds of government agencies, resolve it into a single view of a business, and serve it through an API. Business verification is becoming core infrastructure connecting businesses, banks, and governments, and that’s what we’re building. And our engineers build with AI every day. Earlier this year, agents helped us refactor our entire data pipeline.
Middesk is a Series B company backed by Sequoia and Accel, came out of YC, and was recently named to Forbes’ Fintech 50. We’re looking for folks who like getting close to customers and turning that context into product decisions.

It seems like these jobs have been up for some time; have you been hiring a lot from them? Just waiting for the right person? It's been a bit difficult to raise any sort of email response related to them, at least.
Blackbird | Dev Shop | Remote (US only) | Contract
Blackbird builds web, mobile, IoT products for startups and innovative companies. We work on interesting, greenfield projects, and rely on small, veteran teams who have lots of autonomy. Everyone is a remote contractor, and our work culture is low-drama and highly collaborative. No pointless meetings, no bureaucracy, no egos and lots of time spent building things. Projects typically range from 3-12 months and usually require full time hours (35/week).
We’re looking for senior full stack engineers / CTO consultants / data scientists. We value engineers who are strong technically as well as great communicators. We work with lots of freelancers who appreciate the steady, interesting work.
Our typical stack is TypeScript, React, Postgres, and AWS although it will vary project to project.
If you enjoy moving fast, working with great engineers, and building something from the ground up, you’ll fit right in.
If interested, reach out directly to me at vance [at] blackbird.us with your resume, link to your LinkedIn, and a small blurb on why you think you'd be a good fit. Must be based in the USA and have 5+ years of engineering experience.
We're preparing a U.S. Department of Education SBIR Phase IA proposal to build an assessment reasoning platform for school speech-language pathologists. It implements TTL-MSM, a fully specified decision framework for one of the hardest calls in school eligibility evaluations: whether a student's communication profile reflects a disorder or a difference. Clinicians code each source of evidence, and a fixed rule combines them. The rules are written; the software isn't. The research lead is at Baylor University.
Prototype Developer ($70–95/hr): build a browser-based web app from a written spec, with privacy designed in from the start so it's ready for FERPA-protected student data later. About 15–20 hrs/week for nine months if funded.
Technical Product Lead ($75–100/hr): the bridge between the clinical spec and the engineering. Scope the prototype, turn the spec into requirements, and keep the build on schedule. About 5–8 hrs/week for nine months if funded.
Pre-award scoping (10–15 hrs for the developer, 5–10 for the lead) is unpaid, and funded work is contingent on award. U.S. citizens or permanent residents.

We The Flywheel | Remote | Brand Identity Designer (AI-agent team) | Hourly, flexible hours
We build and run our own brands (race finders, training tools, AI guides, sports media) with a small remote team and a lot of AI agents.
Most of our brands have an identity that is good enough. We want someone with a sharp eye to make them good: logo refinements, lockups, favicons, social and OG images, colour and type rules. It's polish and judgment, not starting from scratch. Our agents do the digging, so you spend your time designing.
CoreWeave | Senior Specialist Field Engineers (Kubernetes, Security, Storage, Compute Infrastructure) | Full-time | Hybrid, 3 days/week in office: San Francisco CA, Sunnyvale CA, or Bellevue WA | $182k-$275k base + bonus + equity
I run the US West Specialist Field Engineering team at CoreWeave. We work hand in hand with the labs pushing the boundaries of AI, on some of the largest GPU Kubernetes clusters in the world. Specialist Field Engineers own the technical side of the customer relationship: architecture, proofs of concept, and the hard debugging nobody else can do. What you learn in the field feeds straight back into the product.
Must live near one of the cities above. This is a hybrid role, and we do not offer relocation.
Must have deep experience in these areas. It's in the title. The work we do goes exceptionally deep, and we need people who are already experts in one of these areas.
* Kubernetes [ https://grnh.se/7j1kydde6us ] You've written a production k8s operator, in go or rust. Bonus: GPU scheduling (device plugins, topology, MIG, RDMA), control plane scaling at thousands of nodes, Slurm, CNCF contributions.
* Security [ https://grnh.se/jxbek1o66us ] You've secured large-scale infrastructure and can trace an identity or isolation problem from the IdP, through the kernel and network, into Kubernetes. Bonus: threat modeling against SOC 2/FedRAMP, confidential computing and attestation, Falco/Tetragon, DPU/GPU/secure boot.
* Storage [ https://grnh.se/137kuvyv6us ] You've built or run a parallel filesystem (VAST, WEKA, Lustre) at scale, and can explain in detail how S3 works under the hood. Bonus: NFS-over-TCP debugging at scale, checkpointing for AI training, CSI drivers, kernel NFS/Lustre/Ceph contributions.
* Compute Infrastructure [ https://grnh.se/q3hmrcf56us ] You've brought up and validated large GPU clusters on GB200/GB300-class hardware, from InfiniBand/RoCE fabric validation thorugh PXE boot and NCCL acceptance. Bonus: firmware/BMC/BIOS, bare metal, Kubernetes, or Slurm.
If you're local and that's you, apply through the links above (they route to me) and mention HN.
The roles descriptions are compelling and attractive in and of themselves. But all details and surrounding context considered, this looks really tough to recruit for.
8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.
What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.
Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.
Perry | Founding Commercial Hire, Founding Account Executive (US), Product Designer, Legal Engineer | London (and New York for US AE) | ONSITE | Full-time
Perry is the legal OS for private capital. We build AI agents that turn a fund's legal documents into operational intelligence: reviewing term sheets and SPAs against the fund's own playbook, tracking rights and obligations across portfolio companies, and flagging MFN and regulatory risk. Founded by fund lawyers, backed by Antler, with paying VC and PE fund customers. New office near Euston.
Founding Commercial Hire (London): our first commercial hire. Own revenue, close a warm pipeline of UK and European funds, and build the sales playbook.

Sidekick Labs | Senior Technical Product Manager | REMOTE (US Timezones) | Full-time | $170k to $230k Base + Equity + Health
Sidekick builds AI security software for enterprises. Our sensors observe AI behavior and use in situ. From those observations, our reasoning pipeline produces an application inventory and a risk picture, allowing us to provide real-time intervention and coaching right when it matters.
Compensation: base salary scaled to experience, meaningful early-stage equity, and 100% covered health insurance for you and your immediate family.
We are a highly senior team. Most of us have been founders or on early founding teams, so we operate with high ownership. The PM team is small, and everyone on it has a real, current AI-assisted practice: we design, prototype, and build with AI tools every day.
The role: You'll spend your time with customers and in the product. You'll run discovery with CISOs and IT teams, guide pilots, and turn what you learn into clear direction for engineering. You'll also build: design and prototype with AI tools, make your own tools for research, analysis, and reporting, and open PRs against the product when that's the fastest way to get something done. On a small team, expect to take on whatever the company needs.
What we're looking for:
- 10+ years building B2B software, at least 5 of them as a PM
- Customer discovery and pilots you ran yourself, ideally with enterprise IT or security teams
- Things you built yourself that you can walk us through: prototypes, internal tools, or merged PRs
- Crisp, clear communication, written and spoken, with customers, engineers, and executives
- Security experience is a plus
To apply: Send an email to hiring@sidekicklabs.com with "Senior Technical Product Manager" in the subject. Include a PDF of your resume, links to your LinkedIn and any GitHub or personal site, and a short description of something you built yourself (a prototype, a tool, a PR): what it does and why you built it.

Strello is an AI front desk for Canadian medical clinics. It answers calls, books and moves appointments, and works directly inside the clinic's EMR. We're physician-founded (I'm a practising rheumatologist), and the product came out of our own front-desk turnover problems.
What you'll do:
- Own inbound leads and respond fast. Screen for fit first: are they on an EMR we integrate with, and is Strello the right answer for their phones?
- Run discovery and demo calls with physicians and clinic managers, then quote, close, send contracts and payment links, and keep the CRM current.
- Lead onboarding: workflow meetings with clinic staff, phone and EMR access, and launch coordination with our engineers.
- Stay the go-to contact after launch, and bring what you hear back to the product team.
You might be a fit if you've worked in sales, or clinic operations (MOA, coordinator, manager), or healthcare SaaS account management, or customer success.
You should be comfortable on the phone and on video with physicians, organized enough to run many clinics in parallel, and happy to help write the playbook at an early-stage company.
Apply: reza@strello.health with a few lines on the clinics or customers you've worked with.
DuckDuckGo - we are looking for candidates that are excited to join us on a mission to raise the standard of trust online. All of our roles are fully-remote, except where specific locations are noted.
We're building an open-source no-code platform for agents, databases, applications, and automations.

Paramark | Software Engineer (L4) | San Francisco HYBRID (3 days/wk) or REMOTE (US) | Full-time | $199K–$249K + equity
Paramark helps Marketing teams optimize spend across all of their channels and programs. There are proven scientific ways to do this, but they are poorly understood and practiced by only a tiny fraction of teams. Our product ingests data from all of our customers' marketing channels and uses it to train open-source ML models for both measurement and experimentation. This makes it possible for any marketer to use these methods.
In this domain, it's hard to figure out what to build, and it's even harder to be both accurate and simple. You'll be joining a small team -- we have four product engineers. That means owning systems end to end and having real influence over what gets built. Your typical project will start with a high level goal, and you will figure out the rest.
Founded 2023, ~16 people, $8M from Greylock, cash-flow positive. Reasonable working hours: when the Mercury News covered the return of 996 culture, we were the counterexample. "We don't think early stage startup life requires 18-hour days, or even 12-hour days." https://www.mercurynews.com/2025/08/25/silicon-valley-startu.... 4 weeks PTO plus federal holidays, medical/dental/vision (100% of employee premiums, 50% for family).
Looking for 8+ years, full-stack. Some exposure to statistics, experimentation, or A/B testing helps.
Stack: TypeScript, React, Python, Postgres. Google Cloud, Kubernetes, FastAPI, taskiq.
Process: intro call; technical phone screen; one-day onsite in SF (travel covered for remote candidates)
Duranta (https://getduranta.com/) is hiring a computer vision engineer, enterprise account representative, and sales representatives. The jobs are work-from-office, in the Seattle area.
We are a small company making SaaS for landscaping companies. We also have our own AI models for property analysis.
Blockrotate (https://blockrotate.com) builds low-latency copy-trading and execution infrastructure for Polymarket and prediction markets.
Copy trading on prediction markets has strange market microstructure. Unlike deep perp DEXes (Binance, Hyperliquid), Polymarket orderbooks are bounded, often thin, and subject to severe adverse selection. When a high-volume leader buys, the book moves immediately. If followers lag by a few hundred milliseconds, or if a platform taxes every order with a 50bps fee, follower alpha drops to zero.
Most existing tools in this space either hit users with high per-trade taker fees or ask them to export and paste their master private key into a database. We took a different approach: isolated per-bot deposit wallets (non-custodial via EIP-1967/1271 proxies) and co-located autonomous Rust workers running delta-sync loops directly against the Polymarket CLOB.
- Squeezing latency out of the execution hot path (delta position calculation, order placement, nonce handling, fill verification).
- Building better execution protection: momentum filters to dodge toxic order flow, fill stabilization windows, and handling thin book liquidity without moving the market against yourself.
- Scaling worker orchestration: our C2 server talks Protobuf to distributed bot workers with monotonic sequence IDs and autonomous reconnect failover. As bot volume scales, we need to keep state reconciliation bulletproof.
Hihi, I'm Alex, co-founder and CEO. Subimage maps infrastructure the way an attacker does so security teams at scale-ups and enterprises can find and fix problems. We're built on Cartography (https://cartography.dev), the open source infra mapping tool we helped create at Lyft and donated to the CNCF. It runs at over 70 companies, including 7 in the Fortune 100.
We're a tiny seed-stage team and our customers are companies your parents have heard of. We have more demand than we can build for, which is why this post exists. This is a chance to get in on the ground floor of something big (or to find out quickly that it won't work; just being upfront about it).
Some of the problems you'd be working on:
- Vulnerability triage with real context: is the asset internet-facing, through which services, is the vulnerable function actually reachable in code, are there compensating controls, and what sensitive data does it reach once exploited, across how many hops.
- Proving that the security fixes our agent proposes won't break anything.
- A near-real-time, self-updating map of an environment so you can see an attack as it happens, plus "time travel" in the graph so you can replay it afterward.
- Teaching an agent to answer questions about a large graph quickly, with only the context it needs and without making mistakes.
- Determining who owns a given resource from messy signals like tags, actions, logs, and files.
Stack: Cartography for ingestion, Neo4j for the graph, Python/FastAPI backend, Svelte frontend with a homegrown WebGL graph renderer, an MCP server that exposes all of it to agents, Terraform for IaC.
Who we're looking for: 3+ years at high-growth companies, strong distributed systems and cloud experience, a real sense of ownership, first-principles thinking, and a willingness to implement gnarly business logic (elegantly, ideally) if it makes a jaded security engineer's life easier. Kubernetes and security knowledge are nice to have, not required. You're in the Bay Area and want to be in the office five days a week.
Process: technical screen, call with the founders, a paid day working with the team, then offer. Health/vision/dental, 401k match, gym, team lunches, unlimited PTO.
Stratirus (a Tennetech company) | AI Developer + Linux Admin (junior to mid) | REMOTE (US only, Central Time hours) | US work authorization required, no sponsorship | Full-time or part-time, contract or hire | $65k to $100k | No agencies
Our optional take-home is a broken Ubuntu server: a service that won't stay up, a nightly report that hasn't gone out in days, and a disk that keeps filling. Fix it, write a script that heals a fresh box, and build a small read-only MCP tool so an AI agent can check on it. 60 to 90 minutes, unpaid, no LeetCode. If that sounds like fun, read on.
We're a small and growing AI and Microsoft 365 consultancy in Franklin, TN. We build AI agents and automation for small and mid-sized businesses, and harden and run the systems underneath: Microsoft 365 tenants, SharePoint, and Linux boxes. We're AI-agnostic and use what fits the client, mostly Claude Code, the Microsoft 365 stack with Copilot and Copilot Studio, Gemini and Gemini Studio, and Oracle OBI. The role is about 60% agent development (MCP servers, Claude Code, Copilot Studio, Power Automate, Gemini) and 40% Ubuntu administration (systemd, Docker, patching, backups, monitoring). PeopleSoft experience is a plus. You'll work directly with clients, so explaining things clearly to a small-business owner matters as much as the code. Early-career and career-switchers welcome.
We expect you to use AI every day. What we hire for is knowing when it's wrong, so one of our three application questions asks about a time it fooled you.
To apply, email your resume to hiring@stratirus.com with short answers to: a time a client or boss made an unreasonable demand and how you handled it; a time an AI confidently gave you a wrong answer you followed, and how you caught it; and something you've built with AI that you still use. Work samples get strong preference. We read every application ourselves and reply to everyone, so please write your answers yourself.
Process: email application, a 45-minute video call where you walk us through something you've built, then a conversation about the role.
Remote within the US only, Central Time business hours. Must be legally authorized to work in the US without visa sponsorship, now or in the future. No recruiters or agencies, please.
ArtCraft | Senior Engineers | SF (Onsite) / Atlanta (Onsite) | $150-$250k + Equity | https://getartcraft.com
Those fucking rent-seeking hyperscalers took the internet away from you, and we’re going to give it back to you and to everyone.
Web 1.0 was great - we had IRC, file sharing, third party chat clients. There were personal websites, forums. Flash was a format kids could use. Everything supported embedding and uploading. Websites actually had APIs and RSS. File sharing, FTP, MP3s, discs, owned media.
Broadband brought our parents and grandparents online, but the shift to the non-technical majority created an opportunity to grossly oversimplify everything. Everything dumbed down into a pre-packaged product. Startups began turning their offerings into walled gardens. Platforms took precedence over protocols. APIs and access and data export went away. And then the rent-seeking began. The era of ownership ended.
Corporate Memphis. Jesus Christ.
We’ve rallied a massive community to build MIT/Apache-licensed alternatives to Adobe, Microsoft Office, Google Workspace, Autodesk, SolidWorks, Slack, Discord, Unreal Engine, OpenRouter, RunPod, and more. The goal is full feature parity, with code anyone can own, inspect, modify, and build on.
We’re digesting second-class apps and platforms into first-class applications, libraries, and APIs with full MCP support. We’re distilling out the good parts, and we’re building the connective tissue that draws them together.
100% of the internet is going to be open source soon, and we’re going to force it open. Loudly.
We have eight figures in run rate revenue, over 20M app downloads and growing. Our community is the best part, and it’s energetic like a wildfire. Everyone resonates with our mission.
We’re missionaries, not mercenaries. We are going to slay the incumbents by being better. Our motto is Google’s old motto - “Don't be evil (tm)”.
We’re a tiny team looking for strong engineers to own major parts of the product: desktop apps, lots of completely open source backend infrastructure, agent workflows, agentic app factories. Stack: Rust, a sprinkle of TypeScript/React, egui, Tauri, MySQL/Postgres, Redis, Elasticsearch, Kubernetes. Lots and lots of Rust. We’re systems engineers by trade, but we like to vibe code Rust. Did I say Rust? Rust. Rust Rust Rust. Maybe that's a filter.
You have to be self-directed and independent. If you want to open source Salesforce with half your time, do it! If you want to work on Solidworks 3D printing applications, great! Writing music apps and DAWs? Go for it! Custom Discord/Slack clients for our custom, completely open source chat API and platform? Hell yeah. Our organization is flat, and we're going to go after everybody and everything.
Everything you build here will be open source. We have no private repos.
We can reclaim the internet. That’s our mission.
Want to know more about us? Look up “Adobe ArtCraft” on YouTube / TikTok / your platform of choice.
If this resonates with you, email hn@storyteller.ai with your Github, a little about yourself and something you’ve built. Write the sentence, “don’t take my RAM, Sam!” so we know you’re one of the good guys.
Complaining about the monotony of Corporate Memphis while forcing your own engineers into the physical monotony of an onsite tech-hub commute in SF or Atlanta is an incredible paradox.
I'm modeling ourselves after Valve, which strongly emphasizes on-site. Valve gives its folks tons of latitude and freedom in exchange for working together in a tightly-knit culture.
I'm not a stickler for showing up to work on time, and I'm a late riser / night owl myself. But the energy of being in a room together physically is extremely hard to beat.
I'm not doing this to micro-manage. I don't have time for that. I'm doing this to be a better version of myself. I get energy from working close to others, and I voraciously learn from my peers. I want people teaching me and helping me be better every single day. That might be selfish, but I thrive in that environment.
What we're doing is weird and experimental and there's a metric ton of discovery in literally every path we take. A culture built around documenting and reading notes isn't going to be fast enough. I'm more hands on than someone who can write 6-pagers and read everyone else's - like Shia LaBeouf's "just do it" energy.
I understand that this isn't a great fit for everyone, and I'm sorry.
I'm not allergic to remote once we're bigger, but we have an enormous mandate, and I want us to tackle it like an RPG final boss in the trenches together. We have a lot to build and prove and learn. Doing it together in person reduces the network hop effects and leads to more serendipity and exchange.
In a years' time, I want us to have built open source alternatives to large portions of the most used software. I want us to create a considerable shake up. I want us to have built new infrastructure to make the web more distributed and more P2P.
I think we stand a better chance if we're in a room together, hacking and engineering together. That's what my gut tells me.
I make films too, and that's frankly something that could never be fully remote.
Aloe | AI Research + AI Engineering roles | ONSITE Vancouver, BC, Canada | Full-time
Aloe is the AI lab for justified belief. We work on research and products that bring epistemic intelligence to AI – compound systems that know why they believe what they do, and what would cause that belief to change. Aloe learns how humans come to answers we rely on: recognizing what's at stake in a decision, understanding evidence and unknowns, working through hard questions with rigor, and learning from the sparse data of experience.
Please read the job description and include in your outreach why you fit not just the role but also our culture. We strive to be Level 5 humans, co-creating a deliberately developmental atmosphere. We get a lot of applications – showing your personality will help you stand out. We have to want to work with you, after all!
* Hyper-growth Series B startup with a proven market fit (since Series A).
* CEO has 2 previous exits, his most recent to PayPal in 2017.
* Backed by PayPal & Legendary Silicon Valley Investor, Khosla.
* Leadership team are industry veterans previously at PayPal, CashApp & Block.
We're building a mobile-first financial wellness platform to help millions of consumers take control of their financial futures.

Estuary is a VC-backed, post–Series A startup powering real-time data replication and transform — from sub-second CDC replication to terabyte-scale OLAP data flows. We’re open-source, developer-first, and focused on making data movement radically simpler across both our Platform and Applications layers.
We’re hiring for:
Head of Engineering — Own the engineering function end-to-end as a partner to our founder CTO: strategy, people, delivery, and operations across a compact but high-leverage team. You’ll grow the leaders already running our teams, set technical strategy jointly with the CTO, and be accountable for what engineering ships and what it costs.
Senior Systems Engineer (Control & Data Plane) — Build the high-performance backbone of our platform: the orchestration, distributed state, and stream transport that keep pipelines at sub-second latency under massive throughput. You’ll work primarily in Rust on fault tolerance, consensus, and networking, and help set the bar for correctness and performance across the team.
Product Manager — Own product areas end-to-end, working closely with engineering and design to shape the roadmap and deliver a great developer experience. Engage with users, translate real-world use cases into product decisions, and help define how modern data infrastructure should feel to build with.
Head of Product Marketing — Lead product marketing as we bring real-time, agent-ready data pipelines to technical buyers, partnering closely with our Head of Marketing, Developer Relations, and the founders. Own positioning, messaging, launches, and competitive narrative, turning what our engineers ship into stories data teams actually care about.
Solutions Engineer — Partner with sales and customers from the first technical call through production, running discovery, demos, and proofs of concept for data engineering and platform teams. You’ll design CDC, streaming, and batch pipelines on Estuary, solve real integration problems hands-on, and feed what you learn back to Product and Engineering.
Customer Success Manager — Own the post-sale relationship for our data engineering and platform customers as our first CS hire. You’ll build onboarding, account health monitoring, and the expansion playbook from scratch while staying technical enough to resolve most issues yourself.
Senior Compliance Engineer — Own our GDPR and PCI DSS programs while keeping our audited SOC 2 and HIPAA programs running smoothly, alongside hands-on ownership of identity, endpoint, and SaaS estate management. This is a governance-first role for someone who has run a compliance program end-to-end, not just contributed to one.
What we’re looking for: People who care about building reliable, maintainable systems and processes and enjoy working with complex APIs, data flows, or customer relationships. We value curiosity, clear communication, and a willingness to learn.
Bonus points for experience with CDC tools, open source contributions, or fast-paced startups.

Hundreds of customers use our data products, including Google, Amazon, Facebook, Intel, and Adobe, across industries such as finance, recruiting, sales, marketing, and security. We’re a fully remote company with a global footprint across 20+ countries. We’re growing, profitable, employee-owned, and have no dependence on outside funding. Applicants from all geographies and backgrounds are welcome. We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely love to do. We’re obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team. Our codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two minutes.Effectively all of our codebase is written in Python, Rust, SQL, JavaScript/TypeScript, and Nix. The core technologies you’ll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.
Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests. Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.
We’re looking for remote junior engineers with 0–3 years of professional software experience and 5+ years of curiosity exploring computers, programming, and technical hobby projects.
This is an open-ended entry role with mentorship and diverse opportunities to work across all areas of our product: databases, distributed systems, infrastructure and tooling, data analysis, machine learning, frontend/backend web development, APIs, data mining, data modeling, and more.
To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, or anything else that shows how you think and build.
Ideally, you’ve already graduated. But if you still have one or more years left of school, please feel free to apply anyway. If you’re the right fit for the team, we’ll figure out a way to accommodate your schedule.
We’re hiring generalist software engineers to work on web applications, data mining, machine learning/data science, data transformation/ETL, data modeling, database scaling, infrastructure, DevOps, and more. We’ll tailor the role to the subset of areas that best match your interests.
Beneficial experience includes PostgreSQL, Python, Rust, Linux, TypeScript, Nix, frontend/backend web development, and data mining.
I’m Kiran, Chief of Staff at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.
Don't Use This Code: https://dutc.io | Training & Consulting | Full-Time (W-2) | Fully Remote (US-only)
Don't Use This Code's mission statement grew out of a joke… let's look at something amazing that will change the way you think about this programming language feature or this open source library… just DON'T USE THIS CODE.
The core principle is: true expertise and expert knowledge is worthwhile to develop and disseminate (and this is true even if the LLM is doing a lot of the typing.) To this end, our goal is to deliver a combination of training, consulting, and hybrid coaching services to clients in the tech industry, in financial services, and at large-scale scientific research facilities. In fact, on the back of some recent successes, we are gearing up to build up a team and dramatically expand this work. Our work involves a lot of data analysis, data visualization, modelling, simulation, and experiment tooling system and infrastructure, and is currently very Python and PyData heavy.
We are looking to hire both junior and senior technical leads, as well as instructors.
We're just beginning to ramp up our hiring process, but provisional job reqs are available:
Given the nature of our clients, we are especially fond of hiring people with background in the sciences, including those in fields like biology or psychology, who have a strong (perhaps even self-taught) technical background.
E-mail with your résumé or LinkedIn and add any thoughts you have on developing and sharing expert knowledge: jobs@dutc.io

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control (https://delta.dev/) that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Simple Analytics | DevOps Engineer | REMOTE (worldwide, any timezone) | Full-time, 32h, 24h possible | €5,000/month (full-time) | https://www.simpleanalytics.com/jobs/devops
Hi HN, I'm Adriaan. Simple Analytics exists thanks to HN: it started with my Show HN in 2018 [1]. Today we're a self-funded, profitable team of four building privacy-first analytics.
Privacy is why we run our own bare-metal servers instead of the cloud. We're preparing for a LOT more traffic, and you'll own the infrastructure and its reliability. We have good documentation. First project: leading the infra side of our Elasticsearch to ClickHouse migration, with Alex, our developer.
Stack: Ansible, OpenTofu, Docker Compose, Grafana, GitHub Actions, TypeScript. Clear async communication matters more than knowing every tool.
You can apply from your terminal:
[1] https://news.ycombinator.com/item?id=18024277Wow, we get a lot of applicants. Thanks!
A tip for the upcoming ones: please tell us about yourself instead of repeating the job ad back to us. Leave your AI off for 10 minutes, and give us those spelling mistakes!
Looks like a fun job, and an interesting company!
As feedback I just want to say, the salary feels low. I work in the Netherlands too and I think I’d have all your requirements. However, the job would be a big step down in salary - that’s also compared to similar roles I see around.
Interesting post!
When you say "Full-time, 32h, 24h possible | €5,000/month (full-time)" is the €5,000/month salary pegged at 40h/week so that the actual payment is scaled up/down based on the number of hours worked per week?
Yes. That’s right. But fixed amount of hours per contract.
Although we are flexible to move days back or forth between weeks.

Pond AI | Head of Engineering (founding-level) | San Francisco | Onsite | Full-time | https://joinpond.ai
Most non-tech businesses know exactly which workflows they want AI agents to handle, but have no one to build, connect and run them. Pond delivers custom AI agents to these businesses through a network of 7k AI builders, with Pond as the platform and security layer over MCP.
We're backed by Tier-1 VCs and a co-inventor of GPT, and we're looking for a hands-on technical leader to own the platform end to end.
You'd be a great fit if you:
- Build full-stack and ship AI agents in production (TypeScript/Python, LLMs, tool use)
- Have worked on payments, agent coordination/MCP, or platform/marketplace products
- Have early-stage startup experience (founder, founding or early engineer) and like to grind

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations - we're already hiring operators in the UK too - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Kanurra | Founding Engineer | New York, NY | ONSITE | $230K to $310K + equity | https://www.kanurra.com/careers/founding-engineer
Every prescription filled on a health plan gets priced and paid at the pharmacy counter in seconds, passing through four or five companies, and the employer paying for it almost never sees what it cost. We're building the platform those claims are priced, paid and audited on, in the open. TPAs and brokers build on it.
I'm the founder and an engineer, and I've written most of what exists. Hiring engineer #1. The problems: paying the same claim exactly once across reversals, rebills and retries; a versioned API that outside companies build their business on; isolating each customer's health data, enforced in Postgres; and drug prices that change retroactively but still have to be explainable. Stack: Python, TypeScript, Postgres, GCP. No healthcare experience needed.
Email me at hello@kanurra.com with something you built and the one thing in it you'd never let change.

Proxima Fusion | Senior Software Engineer (Dev Platform) | Munich, Germany | ONSITE | Full-time
We're building the world's first commercial stellarator fusion power plant. First spin-out from the Max Planck Institute for Plasma Physics, based on Wendelstein 7-X (the largest stellarator ever built), €650M+ raised, teams in Munich, Zurich and Oxford.
Finding a good stellarator design means searching an enormous high-dimensional space, and every candidate design needs heavy plasma physics simulation. That's the compute problem this role owns: cloud + HPC clusters, K8s, Ray, Dask, and the platform work around it (CI/CD, IaC, observability).
You'd sit directly next to the physicists and AI researchers burning through that compute, so you see exactly what your infrastructure unlocks. Python and Linux.
If you've wanted to point your platform engineering skills at something that actually matters, clean, abundant energy, this is about as direct a shot as it gets, and it's happening in Europe.
Interview process: recruiter call, meet the team lead, technical panel, meet the CEO.

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.
There are a lot of companies in the auth space, but we feel like we have something special:
* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)
* A well designed API first approach; one customer compared our APIs to petrichor
* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases, but don't worry, there are plenty more features to add)
* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration
Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Modash.io | Senior Product Engineer | Remote (Europe) | Full-time | €80k–110k | https://modash.io
Modash helps brands find, manage, and pay creators - and helps creators earn a living.
The product looks simple on the surface. Underneath, we index 380M+ public creator profiles across Instagram, TikTok, and YouTube so that 2,700+ brands search, evaluate, manage, and pay creators without drowning in spreadsheets and tabs.
We're looking for Senior Product Engineers who like owning ambiguous problems end-to-end. No perfectly shaped tickets. You talk to customers, understand messy workflows, make product decisions, ship, and own whether it actually works.
The problems we care about: - How do you make a 380M-profile dataset feel fast, trustworthy, and easy to explore? - How do you turn chaotic influencer marketing workflows into product that feels obvious? - How do you build tools that work for both small teams and brands like Stanley, Sennheiser, Birkenstock, and NordVPN??
We're around 90 people, raised an €11M Series A, and ARR is doubling every year. HQ is in Tallinn, engineering is fully remote across Europe. No ticket factory. No seven layers of approval. Small teams, real ownership, hard product problems.

What you'd sell: Platform (Studio, Server, infra to run/debug/observe agents in production, hosted or self-hosted for regulated orgs), Agent Builder (agents without code), and Concierge (embedded Mastra engineers working alongside customer teams). Full-cycle, mid-market: Series A–C, often with regulatory or infra constraints, sales cycles of a few weeks, talking to eng leaders.
You have: Closed full-cycle deals in dev tools, OSS, infra, or AI. Enough technical depth to come across as a smart PM with engineers: understand their use cases and scope a solution. Founder or founder mentality. Comfort with a product that ships something new every week.

Tandem Health | Engineers, Designers, PMs | On-site in Stockholm, Sweden | Full time
At Tandem Health we're building the AI-native operating system for clinics, so clinicians can focus on care rather than administration. We're building, launching and iterating quickly, and already support more than 10,000 care organisations across 14 European markets, including most of the NHS. We recently raised a $100M Series B to go further, faster.
It started with our AI medical scribe, which listens in to the patient-clinician encounter to generate medical records and saves clinicians 5-10 minutes per patient. Today our AI medical assistant supports clinicians before, during and after each visit, with medical coding and clinical decision support, three products certified as medical devices under EU MDR.
We're expanding our Stockholm team with exceptionally driven builders in a wide range of roles.

UNICEF - REMOTE backend dev - Digital Inclusion Division, Connectivity Credits
We're building a marketplace where local ISPs connect schools and health centers to the internet, prove it via telemetry, and get access to discounted backhaul, IP transit and compute from large infracos.
Currently in pilots in Mexico, Kenya, South Africa, Malawi.
Looking for 1 dev to join a small tech team (3 people) working on this protocol and marketplace, which sits on top of a larger tech team of 30 people at UNICEF Digital Inclusion. Not your typical UN job or culture.
https://jobs.unicef.org/en-us/job/596538/consultancy-connect...
The rest of the team are in Barcelona/Geneva, but this role is remote. 6 month contract to start, with the aim to continue long term.
If you want real talent, consider lowering the barrier to entry by not having people have to add in their work experience, education, and fill out a DOCX in addition to everything else.
Thank you for sharing this role. Blockchain for an ISP marketplace makes a lot of sense, especially in a humanitarian context where tech sovereignty matters. I'll definitely be applying!
NEO Holdings (stealth, regulated commodity markets infrastructure) | Malibu, CA | ONSITE (SoCal preferred) or REMOTE (US) | Full Time
We are a funded and backed venture building the regulated base layer for tokenized commodities including the US-regulated trading venue, Mint and benchmarks, bridging institutional commodity markets and on-chain finance. Commodity markets trade tens of trillions a year on infrastructure designed for paper-based trading; we are what comes next. Launching Q1 2027.
Roles currently available:
VP of Engineering: owns the platform end to end, from on-chain contracts (Avalanche) to the trading engine, custody integrations and institutional-grade security and operations. A VP or SVP who still builds and ships, not one who just manages others; you will have a real say in the architecture before we finalize it and will work with leaders in tech and commodities. You must have done this before: delivered a trading venue or institutional token issuance, end to end. $200K to $300K base plus equity depending on experience and location.
Lead Product Manager: works with our partners and customers to ensure the launch product suite is fit for purpose and aligns participant experience across onboarding, trading, collateral and reporting. You must have shipped products in a regulated financial venue, exchange, clearing house or institutional crypto platform, you write the spec yourself, and you have run product through a regulator's questions. $150K to $240K base plus equity.
We hire on written replies and quality of CVs. We read every reply ourselves, so please write yours yourself. Send a short note on what you have built that is closest to the seat, with references, to careers@neo.co and put the role in the subject line. Please mention you came from HN.

Memorang | Product Engineers + Technical Project Manager | Full-Time | Los Angeles (or US remote for exceptional hires)
Memorang is an "AI stack for education" that helps organizations build, launch, and monetize AI-powered learning and assessment products. Think Vercel plus Shopify for EdTech. We currently operate on an enterprise model, serving as the AI technology and commercial partner behind new product lines for organizations like ETS, McGraw-Hill, Pearson, and the ACT.
We’re hiring for two roles:
Product Engineers Own features from the first rough idea to production. You’ll work across AI workflows, backend systems, and user interfaces, making product decisions along the way. We’re looking for engineers who ask good questions, care about the details users notice, and can turn an ambiguous problem into something useful and shipped.
Stack: TypeScript, React/Next.js, React Native, Node.js, AWS Lambda, Postgres, and Neo4j.
Technical Project Manager Turn complex work into clear plans and keep delivery moving. You’ll coordinate across engineering, design, and customer needs, surface dependencies early, resolve blockers, and keep owners and timelines clear as priorities change.
Ideal background: an engineer who moved into project management, with startup experience and enough technical depth to discuss APIs, architecture, and AI workflows with the people building them.
Why join? A small team, meaningful ownership, and products used by millions. You’ll help shape what we build and how we work, with a short path from an idea to seeing it in users’ hands.
Remote-first, async-friendly, with health and wellness stipends, home-office support, and paid time off.
Apply: Email careers@memorang.com with your CV, a few sentences about what interests you, and something you’re proud to have built or delivered.
Quantum Rise | Chicago IL or Remote (US, Brazil or EU) | Full-time | No visa sponsorship | https://www.quantumrise.com/
Quantum Rise is an AI-forward consulting startup serving the mid-market in the US and larger enterprises in LATAM. We see companies in multiple industries struggling to understand how to leverage artificial intelligence in their day-to-day operations, trying to understand what their existing workforce now needs to know, or trying to understand whether they're about to be disrupted and need to change how their existing processes work. Many have business problems which "traditional" machine learning could help with even prior to the current GenAI hype cycle, but for whatever reason hadn't prioritized doing until now. Many have employees looking to incorporate agentic AI safely and effectively across different business areas. We try and help getting a handle around these issues and designing outcome-driven solutions.
Agentic AI Engineer: You'll work directly with clients to benchmark, train and deploy agentic systems for industry-specific problems. We're looking for someone deeply embedded in agentic engineering practice across vendors and platforms. Companies are looking for ways to leverage agentic systems to upskill their practitioners and need help navigating a new, powerful scary world.
AI Solutions Engineer: You're someone who has experience in traditional machine learning and data science applications in addition to more recent agentic systems.
We think of these two roles as complementary -- agentic AI solutioners help clients understand the forefront, whereas pure AI solutioners help them pick and build the right solution even if it isn't an LLM.
Both are front-facing development roles for someone who loves both tech and tackling real business problems. We love people with prior experience in multiple industries.

I'm the CEO, previously CTO of Metaculus and creator of Google's current internal prediction market. FutureSearch is about ten people, remote-first and concentrated in London.
We're hiring (US pay, adjusted to the local market elsewhere):

Mesmer (YC P25) | Founding Engineer | Berlin | ONSITE | VISA + relocation | €100–140k + 0.5–1% equity
Mesmer builds software factories for engineering teams. Keeping a team at the state of the art with agents is a full-time job, so we do it for our customers: we're always finding the biggest bottleneck in how their team ships and fixing it in their factory.
As a founding engineer you'd do both halves. You'd work in customers' factories, at the frontier of how software gets built with agents, and you'd build the product that makes that work repeatable. We're seven people, repeat founders and CTOs, in one office in Berlin.
We're looking for senior engineers who use coding agents every day and have strong opinions about how the work around them should change.
About two weeks from first call to offer, no live coding or take-home. Email hiring@mesmer.co with a short intro and something you've built.

VALIS (Valis Insights) | Software Engineer, new product line | REMOTE (US, East Coast hours) | Full-time | $125k-$155k + equity
I'm Caleb, co-founder/CTO. VALIS builds data products for scrap metal recyclers. Our product images, weighs, and classifies scrap metal, and our platform turns that into actionable quality analytics to improve physical ops at plants across the US. Recycled metal takes a fraction of the energy of mined metal, and better data means more of it gets recovered.
We're hiring an engineer to build our next product line: a production tracking and analytics platform for recycling plants, extended from our existing product. We're a small team (<10 ppl). What you'd work on (ideate, build, deploy, own):
- Modeling a complex (and intellectually stimulating) physical process
- Agentic features that dig through production and quality data, surface trends, flag anomalies, and notify the right people
- Working directly with customers: regular calls with operators and plant managers, plus a few site visits a year
You should have 3+ YoE, strong data modeling fundamentals, and enjoy owning ambiguous problems end to end. We care more about how you think than what exactly you've used. Recycling, ERP/MES, or physical ops software experience is a plus.
Our stack: React/TypeScript, C#/.NET, PostgreSQL, AWS.
US work authorization required; no sponsorship.

I’m Marcelus Brice, founder of TheraPlug (https://theraplug.health). We’re building a behavioral health platform focused on making it easier for patients to find appropriate therapists and access care through insurance, starting in Detroit.
We’re looking for a hands-on technical leader who can build alongside a lean team and help recruit its founding engineers. You don’t need a previous CTO title, but you should have shipped and operated production software.
The product will support iOS, Android and responsive web, including:
• Patient and provider onboarding, scheduling and secure messaging. • AI-assisted therapist matching based on clinical needs, preferences, insurance and availability. • Provider credential verification and payer enrollment workflows. • Insurance eligibility checks and estimated patient costs. • Secure video sessions and clinician-reviewed AI documentation.
Relevant experience includes full-stack development, mobile apps, healthcare integrations, sensitive-data security and practical AI implementation. We value clear architecture, accessible design and thoughtful use of established services.
Compensation: We are pre-funding and cannot offer an immediate cash salary. We’re seeking someone interested in an equity-first founding role, with a planned transition to salary when funding supports payroll. Equity, responsibilities, time commitment and compensation triggers would be agreed in writing before work begins. Funding timing is not guaranteed.
To start a conversation, email marcelus@theraplug.health with: • Products you’ve built and your specific contribution. • Relevant healthcare, security or AI experience. • Your location and realistic availability before funding. • Your interest in leading and assembling a small development team.

Mozilla | Sr. Staff Software Engineer, Browser (New Products) | REMOTE (US or Canada) | Full-time
Mozilla's New Products group is a small team building new things on top of browser engine technology. We're hiring a hands-on, senior IC to run experiments inside browser engine internals and find out which ideas actually hold up.
What you'd do: design and build experiments in engine subsystems (DOM, layout, accessibility, JS runtime, networking), prototype features that let programs interact with web pages reliably, and measure everything. That means repeatable benchmarks, profiling overhead, and writing up the experiments that didn't work too. You'll use AI tools heavily, but you'll verify what they produce by testing and measuring it.
You likely have: deep experience in at least one browser subsystem, strong C++ or Rust, comfort in a very large codebase, a solid grasp of how the web platform behaves, and a real interest in AI agents and their tooling. Contributions to Gecko, Servo, Blink or WebKit are a big plus.

Every hardware buyer knows this PO. It goes out, and then nothing happens: no ack, no ship date, just chasing over email while the spreadsheet and the ERP disagree. Silkline is the AI operating system for procurement at companies building satellites, launch vehicles, reactors, and robots (Machina Labs, Astranis, K2 Space, Castelion, Antares). We 5x'd our customer base, and our customers' parts can't wait.

Curiosity (https://curiosity.ai) | Forward Deployed Engineer, DevOps Architect | Toulouse, France | ONSITE | Full-time (CDI) | Visa support
Curiosity Studio builds internal apps and agents from a plain description, on a company's connected data and inside its permissions. It runs on premises or in a private cloud, with any LLM. We're bootstrapped, profitable and based in Munich. Our customers are large industrial and regulated companies, Airbus among them, and Studio has 30TB+ of data connected in production.
We are starting a team in Toulouse that works at customer sites, in French and English, along with the engineers who build Studio.
Forward Deployed Engineer: take a customer's problem from the first workshop to production. You decide with them what Studio should build, connect their systems, model the data as a graph, and oversee the C#/.NET connectors and services it needs. You also ship features and agents on top.
DevOps Architect: Own deployments in customer environments, from the first technical discussion to handover, on private clouds or data centers. Networking, IAM, Linux, Docker, monitoring, backups, upgrades, incidents. You also write code alongside the forward deployed engineers.
We're looking for hands-on builders who enjoy working directly with customers. Full-stack project experience preferred. Fluent French and English required.
Interviews: a 30 minute call, a technical conversation, then the founders.

Juro | AI Engineer (Agentic team) | London, UK | REMOTE (UK) | Full-time | £115k + equity
Juro is an AI contract automation platform used by in-house legal and business teams. Our Agentic team builds Operator, the agent that works across contracts inside Juro: it answers questions and takes action on legal data. You'd build the tools that let it act across the product, own parts of the agent harness (planning, tool use, context) and put evals around what you ship, together with our QA team.
Stack: TypeScript/Node.js, MongoDB, pgvector, AWS Bedrock, LiteLLM, Mastra, some React. Engineers pick their own AI tooling (Claude Code, Codex, Cursor...) and we pay for the usage.
We're looking for programmers first who now build with LLMs, and who have shipped something people use. Years of ML matter less to us than what you've built. We apply models, we don't train them.
Process: 30-min intro call, interview with the hiring manager, a build review where you walk us through something you've built, and a short chat with our CTO. We reply to every applicant.
You'll work from the UK. For exceptional candidates we can sponsor a UK Skilled Worker visa, whether you're relocating or already in the UK. If you need sponsorship, say so in your application.

We're looking for help in further developing and hardening our embedded Linux components, which work in tandem with FPGAs and our custom ASICs to read out neural data. Some of the ongoing efforts are: HIL testing on real devices, integrating new sensor ASICs, maintaining our Yocto build system, exploratory work on prototypes, improving our clinical UX, and improving the core code that receives and massages data. The code is largely written in Rust with a little Typescript, (and bash, and bitbake recipes, etc).
You'll be expected to have experience constructing reliable and understandable software in Linux, and some level of experience in building and interacting with embedded hardware. Rust experience is ideal but not necessary. We're not looking for a specific number of YoE, but for motivated and hungry engineers who want to push the frontier of brain-machine interfaces.

Ethan here, founder of Jump.
Machine shops lose jobs because quoting is slow. A part comes in, someone has to read the drawing, figure out how to make it, and price it, and that can take hours. Many shops also can't put customer drawings in the cloud (ITAR, export control, or just customers who say no).
We're building Jump Quote: AI that reads a shop's drawings and drafts quotes in minutes, running on the shop's own computer. We're starting with a small group of founding CNC shops. Long term, we want anyone to be able to make anything, anywhere.
We're hiring founding engineers first (software/AI and manufacturing), but every role is open. If you're exceptional at something a startup needs, apply.
We care about kindness, honesty, ambition and intelligence. We don't care where you went to school or who you've worked for. We care that you have a winning mindset and can learn and ship fast.
How it works: we start now, remote within the US. In January 2027 we're together in person in Miami, and that's when the $140K–$160K + equity package starts. You need to be authorized to work in the US for at least the next 3 years; we can't sponsor visas.

Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.
We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!
We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.
You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows. Most importantly, the technology you build will have real impact on real people - clinics staying open, clinicians getting paid, patients getting care.
This is an opportunity to work in a fast paced, high ownership environment while solving real problems in healthcare.

University of Cambridge, University of Manchester | PhD in AI / Earth Observation / Environmental Science | ONSITE | UK home fee status only | £30k tax-free annual stipend
Our group at Cambridge works on Earth Observation foundation models (Tessera: v1 https://arxiv.org/abs/2506.20380, v2 https://arxiv.org/abs/2607.03949, https://geotessera.org/) and we've started a collaboration with Manchester to understand how they can be used to improve pollution models and then environmental decision making in general. This involves training new models and doing high-resolution inference across national or even global scales, as well as figuring out how to use that data to help policymakers make better decisions.
As part of this work we have a PhD studentship through the joint Manchester-Cambridge Centre for Doctoral Training for AI in Decision Making for Complex Systems. This involves one year at Manchester doing taught postgraduate study and then three years at Cambridge for the PhD.
Our work is all open source and involves solving significant compute and data challenges. Training our current-generation model takes ~250k GPU hours and a single year of global inference needs to move over 5.5 petabytes of data through the inference pipeline. This project would suit someone with strong machine learning and software engineering experience. We can help you build the atmospheric science and Earth Observation skills.
We are a highly collaborative group who spend our time not only on foundational research but also on developing applications with practitioners and decision makers. Our work sees use in many industrial, academic and government environments for problems like crop classification, tree species mapping and change detection.
You can find out more here: https://www.findaphd.com/phds/project/from-satellite-to-stre... - if you have questions about the project you can contact me, Sadiq Jaffer, at sj514@cam.ac.uk . For questions about the application process you'll want aidecisionscdt@manchester.ac.uk .

eventfirst | Senior Full-Stack Engineer | Berlin, Germany | REMOTE (CET) | Full-time | eventfirst.com
We are applying AI to organize corporate events.
We are looking for a senior engineer with at least ten years of full stack experience, a strong focus on product and UX, and some experience building an AI chat based product.
Our tech stack is Typescript, React, Next.js and Tailwind. On the backend we use Drizzle with Neon, deployed and monitored via Vercel. Agents and background jobs are executed via trigger.dev. This gives us a killer DX because the entire tech stack supports preview branching. This allows coding agents to work in parallel on different features and verify their work independently very close to what will run in prod. CI is fast (2-3 min) and coverage is good enough to deploy to prod many times per day.
Please note that we are working remotely in the CET timezone. Having some remote experience is a plus.
We have pre-seed funding from a major US VC and are experienced founders. You’ll be working alongside the founders (ex-Apple, ex-Airbnb, ex-Tulip, ex-Tourlane) and will have a chance to shape the company, product and of course the engineering culture.

humans& | Product Engineer (Member of Technical Staff) | San Francisco | ONSITE | Full-time
humans& is a human-centric frontier AI lab. Our view is that AI should help people work together, so it has to understand people and the relationships between them, not just tasks.
Last month we launched Boba (https://boba.app), an assistant you can text one-on-one or add to a group chat. It runs on Ampersand, our first model, trained with RL over millions of simulated days with thousands of simulated people. Boba keeps track of your goals for weeks or months, sets up reminders and calendar invites, uses email and searches the web. In a group chat it reads social context and decides when to speak up and when to stay quiet. Early users have sent it more than a million messages.
Looking for product engineers who have done exceptional work on how humans and computers interact. You’ll build the product side of this: new interaction patterns for an AI that lives in group chats, remembers people and acts for them.
The founding team comes from xAI, Google DeepMind, OpenAI, Stanford and MIT. Our investors include NVIDIA, GV and SV Angel.

myDataValue | Founding Product Engineer | London (Canary Wharf) | HYBRID, 2 days/week in office | up to £90k + up to 1% equity | https://www.mydatavalue.com/founding-product-engineer/
We build AI agents that run revenue for short-term rental and hotel operators on Booking.com and Airbnb: live prices, promotions and visibility on real portfolios, plus an MCP connector so customers work their accounts from Claude and ChatGPT.
Our engineers no longer type most of the code. Claude Code and Codex do. The hard part is knowing what to build, how it should fit together, and whether what the agent wrote is actually right. You will talk to customers, own the architecture, write the briefs, and catch what the agent missed.
We do not care which language you know.
We care that you can do architecture (single source of truth, clear boundaries, the right layer for a fix) and that you already ship this way.
Big bonus if you have worked on hotels, short-term rentals or dynamic pricing.
Small team, paying customers, hard problems (private OTA APIs, PMS integrations, pricing decisions that move real money). Three interview stages, no take-home. Email me (CTO) directly: martin@mydatavalue.com

The ideal candidate has 5+ years experience building iOS apps from zero to production (Swift, SwiftUI, UIKit, and modern iOS frameworks), and has worked in a startup environment in the past. Positive experience with AI coding tools is a plus.
Applicants who take the time to use the platform and test it out and give their thoughts, will be given priority. We are only hiring applicants in the US, Canada, and Japan at the moment.

ORFF Maestra | Prototype Developer; Technical Product Lead | REMOTE (US only) | Contract, part-time | https://orffmaestra.com
We're preparing a U.S. Department of Education SBIR Phase IA proposal to build an assessment reasoning platform for school speech-language pathologists. It implements TTL-MSM, a fully specified decision framework for one of the hardest calls in school eligibility evaluations: whether a student's communication profile reflects a disorder or a difference. Clinicians code each source of evidence, and a fixed rule combines them. The rules are written; the software isn't. The research lead is at Baylor University.
Prototype Developer ($70–95/hr): build a browser-based web app from a written spec, with privacy designed in from the start so it's ready for FERPA-protected student data later. About 15–20 hrs/week for nine months if funded.
Technical Product Lead ($75–100/hr): the bridge between the clinical spec and the engineering. Scope the prototype, turn the spec into requirements, and keep the build on schedule. About 5–8 hrs/week for nine months if funded.
Pre-award scoping (10–15 hrs for the developer, 5–10 for the lead) is unpaid, and funded work is contingent on award. U.S. citizens or permanent residents.

Cologne, Germany | UMH | Product Engineer | Full-time | 70k - 100k EUR | ONSITE (part remote)
Hi, Alex and Jeremy here from UMH.
8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.
What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.
Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.

Sidekick Labs | Senior Technical Product Manager | REMOTE (US Timezones) | Full-time | $170k to $230k Base + Equity + Health
Sidekick builds AI security software for enterprises. Our sensors observe AI behavior and use in situ. From those observations, our reasoning pipeline produces an application inventory and a risk picture, allowing us to provide real-time intervention and coaching right when it matters.
Compensation: base salary scaled to experience, meaningful early-stage equity, and 100% covered health insurance for you and your immediate family.
We are a highly senior team. Most of us have been founders or on early founding teams, so we operate with high ownership. The PM team is small, and everyone on it has a real, current AI-assisted practice: we design, prototype, and build with AI tools every day.
The role: You'll spend your time with customers and in the product. You'll run discovery with CISOs and IT teams, guide pilots, and turn what you learn into clear direction for engineering. You'll also build: design and prototype with AI tools, make your own tools for research, analysis, and reporting, and open PRs against the product when that's the fastest way to get something done. On a small team, expect to take on whatever the company needs.
What we're looking for:
- 10+ years building B2B software, at least 5 of them as a PM
- Customer discovery and pilots you ran yourself, ideally with enterprise IT or security teams
- Things you built yourself that you can walk us through: prototypes, internal tools, or merged PRs
- Crisp, clear communication, written and spoken, with customers, engineers, and executives
- Security experience is a plus
To apply: Send an email to hiring@sidekicklabs.com with "Senior Technical Product Manager" in the subject. Include a PDF of your resume, links to your LinkedIn and any GitHub or personal site, and a short description of something you built yourself (a prototype, a tool, a PR): what it does and why you built it. Include a link if you can share one.

Strello Health | Toronto (hybrid in-person/virtual)
Clinic Sales & Onboarding Lead | https://strello.health
Strello is an AI front desk for Canadian medical clinics. It answers calls, books and moves appointments, and works directly inside the clinic's EMR. We're physician-founded (I'm a practising rheumatologist), and the product came out of our own front-desk turnover problems.
What you'll do: - Own inbound leads and respond fast. Screen for fit first: are they on an EMR we integrate with, and is Strello the right answer for their phones?
- Run discovery and demo calls with physicians and clinic managers, then quote, close, send contracts and payment links, and keep the CRM current.
- Lead onboarding: workflow meetings with clinic staff, phone and EMR access, and launch coordination with our engineers.
- Stay the go-to contact after launch, and bring what you hear back to the product team.
You might be a fit if you've worked in sales, or clinic operations (MOA, coordinator, manager), or healthcare SaaS account management, or customer success.
You should be comfortable on the phone and on video with physicians, organized enough to run many clinics in parallel, and happy to help write the playbook at an early-stage company.
Apply: reza@strello.health with a few lines on the clinics or customers you've worked with.

Paramark | Software Engineer (L4) | San Francisco HYBRID (3 days/wk) or REMOTE (US) | Full-time | $199K–$249K + equity
Paramark helps Marketing teams optimize spend across all of their channels and programs. There are proven scientific ways to do this, but they are poorly understood and practiced by only a tiny fraction of teams. Our product ingests data from all of our customers' marketing channels and uses it to train open-source ML models for both measurement and experimentation. This makes it possible for any marketer to use these methods.
In this domain, it's hard to figure out what to build, and it's even harder to be both accurate and simple. You'll be joining a small team -- we have four product engineers. That means owning systems end to end and having real influence over what gets built. Your typical project will start with a high level goal, and you will figure out the rest.
Founded 2023, ~16 people, $8M from Greylock, cash-flow positive. Reasonable working hours: when the Mercury News covered the return of 996 culture, we were the counterexample. "We don't think early stage startup life requires 18-hour days, or even 12-hour days." https://www.mercurynews.com/2025/08/25/silicon-valley-startu.... 4 weeks PTO plus federal holidays, medical/dental/vision (100% of employee premiums, 50% for family).
Looking for 8+ years, full-stack. Some exposure to statistics, experimentation, or A/B testing helps.
Stack: TypeScript, React, Python, Postgres. Google Cloud, Kubernetes, FastAPI, taskiq.
Process: intro call; technical phone screen; one-day onsite in SF (travel covered for remote candidates)

Blockrotate| Senior Systems / Rust Engineer | Remote (US/EU timezones preferred) | Full-time | $130k - $170k + Equity
Blockrotate (https://blockrotate.com) builds low-latency copy-trading and execution infrastructure for Polymarket and prediction markets.
Copy trading on prediction markets has strange market microstructure. Unlike deep perp DEXes (Binance, Hyperliquid), Polymarket orderbooks are bounded, often thin, and subject to severe adverse selection. When a high-volume leader buys, the book moves immediately. If followers lag by a few hundred milliseconds, or if a platform taxes every order with a 50bps fee, follower alpha drops to zero.
Most existing tools in this space either hit users with high per-trade taker fees or ask them to export and paste their master private key into a database. We took a different approach: isolated per-bot deposit wallets (non-custodial via EIP-1967/1271 proxies) and co-located autonomous Rust workers running delta-sync loops directly against the Polymarket CLOB.
Stack:
- Backend: Rust, Tokio, Axum, Protobuf over WebSockets, SQLite (WAL mode)
- Trading Engine: Custom Polymarket CLOB & Data API clients, EIP-712 signing, dynamic slippage ladders, momentum filters, circuit breakers
- Frontend: Next.js 16, React 19, TypeScript, Tailwind CSS
What you’d actually work on:
- Squeezing latency out of the execution hot path (delta position calculation, order placement, nonce handling, fill verification).
- Building better execution protection: momentum filters to dodge toxic order flow, fill stabilization windows, and handling thin book liquidity without moving the market against yourself.
- Scaling worker orchestration: our C2 server talks Protobuf to distributed bot workers with monotonic sequence IDs and autonomous reconnect failover. As bot volume scales, we need to keep state reconciliation bulletproof.
- Investigating and exploiting prediction market quirks (rebate structures, orderbook snapshotting, MEV/relayer bottlenecks).
What we look for:
- Strong async Rust experience (Tokio, concurrency, practical memory management).
- Experience dealing with websockets, exchange orderbooks, or trading infrastructure

Subimage (YC W25) | Founding Engineer | San Francisco, CA | ONSITE (5 days/week) | Full-time | $170K–$230K + 0.5%–1.0% equity | https://subimage.io
Hihi, I'm Alex, co-founder and CEO. Subimage maps infrastructure the way an attacker does so security teams at scale-ups and enterprises can find and fix problems. We're built on Cartography (https://cartography.dev), the open source infra mapping tool we helped create at Lyft and donated to the CNCF. It runs at over 70 companies, including 7 in the Fortune 100.
We're a tiny seed-stage team and our customers are companies your parents have heard of. We have more demand than we can build for, which is why this post exists. This is a chance to get in on the ground floor of something big (or to find out quickly that it won't work; just being upfront about it).
Some of the problems you'd be working on:
- Vulnerability triage with real context: is the asset internet-facing, through which services, is the vulnerable function actually reachable in code, are there compensating controls, and what sensitive data does it reach once exploited, across how many hops.
- Proving that the security fixes our agent proposes won't break anything.
- A near-real-time, self-updating map of an environment so you can see an attack as it happens, plus "time travel" in the graph so you can replay it afterward.
- Teaching an agent to answer questions about a large graph quickly, with only the context it needs and without making mistakes.
- Determining who owns a given resource from messy signals like tags, actions, logs, and files.
Stack: Cartography for ingestion, Neo4j for the graph, Python/FastAPI backend, Svelte frontend with a homegrown WebGL graph renderer, an MCP server that exposes all of it to agents, Terraform for IaC.
Who we're looking for: 3+ years at high-growth companies, strong distributed systems and cloud experience, a real sense of ownership, first-principles thinking, and a willingness to implement gnarly business logic (elegantly, ideally) if it makes a jaded security engineer's life easier. Kubernetes and security knowledge are nice to have, not required. You're in the Bay Area and want to be in the office five days a week.
Process: technical screen, call with the founders, a paid day working with the team, then offer. Health/vision/dental, 401k match, gym, team lunches, unlimited PTO.

Stratirus (a Tennetech company) | AI Developer + Linux Admin (junior to mid) | REMOTE (US only, Central Time hours) | US work authorization required, no sponsorship | Full-time or part-time, contract or hire | $65k to $100k | No agencies
Our optional take-home is a broken Ubuntu server: a service that won't stay up, a nightly report that hasn't gone out in days, and a disk that keeps filling. Fix it, write a script that heals a fresh box, and build a small read-only MCP tool so an AI agent can check on it. 60 to 90 minutes, unpaid, no LeetCode. If that sounds like fun, read on.
We're a small and growing AI and Microsoft 365 consultancy in Franklin, TN. We build AI agents and automation for small and mid-sized businesses, and harden and run the systems underneath: Microsoft 365 tenants, SharePoint, and Linux boxes. We're AI-agnostic and use what fits the client, mostly Claude Code, the Microsoft 365 stack with Copilot and Copilot Studio, Gemini and Gemini Studio, and Oracle OBI. The role is about 60% agent development (MCP servers, Claude Code, Copilot Studio, Power Automate, Gemini) and 40% Ubuntu administration (systemd, Docker, patching, backups, monitoring). PeopleSoft experience is a plus. You'll work directly with clients, so explaining things clearly to a small-business owner matters as much as the code. Early-career and career-switchers welcome.
We expect you to use AI every day. What we hire for is knowing when it's wrong, so one of our three application questions asks about a time it fooled you.
To apply, email your resume to hiring@stratirus.com with short answers to: a time a client or boss made an unreasonable demand and how you handled it; a time an AI confidently gave you a wrong answer you followed, and how you caught it; and something you've built with AI that you still use. Work samples get strong preference. We read every application ourselves and reply to everyone, so please write your answers yourself.
Process: email application, a 45-minute video call where you walk us through something you've built, then a conversation about the role.
Remote within the US only, Central Time business hours. Must be legally authorized to work in the US without visa sponsorship, now or in the future. No recruiters or agencies, please.

ArtCraft | Senior Engineers | SF (Onsite) / Atlanta (Onsite) | $150-$250k + Equity | https://getartcraft.com
Those fucking rent-seeking hyperscalers took the internet away from you, and we’re going to give it back to you and to everyone.
Web 1.0 was great - we had IRC, file sharing, third party chat clients. There were personal websites, forums. Flash was a format kids could use. Everything supported embedding and uploading. Websites actually had APIs and RSS. File sharing, FTP, MP3s, discs, owned media.
Broadband brought our parents and grandparents online, but the shift to the non-technical majority created an opportunity to grossly oversimplify everything. Everything dumbed down into a pre-packaged product. Startups began turning their offerings into walled gardens. Platforms took precedence over protocols. APIs and access and data export went away. And then the rent-seeking began. The era of ownership ended.
Corporate Memphis. Jesus Christ.
We’ve rallied a massive community to build MIT/Apache-licensed alternatives to Adobe, Microsoft Office, Google Workspace, Autodesk, SolidWorks, Slack, Discord, Unreal Engine, OpenRouter, RunPod, and more. The goal is full feature parity, with code anyone can own, inspect, modify, and build on.
We’re digesting second-class apps and platforms into first-class applications, libraries, and APIs with full MCP support. We’re distilling out the good parts, and we’re building the connective tissue that draws them together.
100% of the internet is going to be open source soon, and we’re going to force it open. Loudly.
We have eight figures in run rate revenue, over 20M app downloads and growing. Our community is the best part, and it’s energetic like a wildfire. Everyone resonates with our mission.
We’re missionaries, not mercenaries. We are going to slay the incumbents by being better. Our motto is Google’s old motto - “Don't be evil (tm)”.
We’re a tiny team looking for strong engineers to own major parts of the product: desktop apps, lots of completely open source backend infrastructure, agent workflows, agentic app factories. Stack: Rust, a sprinkle of TypeScript/React, egui, Tauri, MySQL/Postgres, Redis, Elasticsearch, Kubernetes. Lots and lots of Rust. We’re systems engineers by trade, but we like to vibe code Rust. Did I say Rust? Rust. Rust Rust Rust. Maybe that's a filter.
You have to be self-directed and independent. If you want to open source Salesforce with half your time, do it! If you want to work on Solidworks 3D printing applications, great! Writing music apps and DAWs? Go for it! Custom Discord/Slack clients for our custom, completely open source chat API and platform? Hell yeah. Our organization is flat, and we're going to go after everybody and everything.
Everything you build here will be open source. We have no private repos.
We can reclaim the internet. That’s our mission.
Want to know more about us? Look up “Adobe ArtCraft” on YouTube / TikTok / your platform of choice.
If this resonates with you, email hn@storyteller.ai with your Github, a little about yourself and something you’ve built. Write the sentence, “don’t take my RAM, Sam!” so we know you’re one of the good guys.
Complaining about the monotony of Corporate Memphis while forcing your own engineers into the physical monotony of an onsite tech-hub commute in SF or Atlanta is an incredible paradox.
I'm modeling ourselves after Valve, which strongly emphasizes on-site. Valve gives its folks tons of latitude and freedom in exchange for working together in a tightly-knit culture.
I'm not a stickler for showing up to work on time, and I'm a late riser / night owl myself. But the energy of being in a room together physically is extremely hard to beat.
I'm not doing this to micro-manage. I don't have time for that. I'm doing this to be a better version of myself. I get energy from working close to others, and I voraciously learn from my peers. I want people teaching me and helping me be better every single day. That might be selfish, but I thrive in that environment.
What we're doing is weird and experimental and there's a metric ton of discovery in literally every path we take. A culture built around documenting and reading notes isn't going to be fast enough. I'm more hands on than someone who can write 6-pagers and read everyone else's - like Shia LaBeouf's "just do it" energy.
I understand that this isn't a great fit for everyone, and I'm sorry.
I'm not allergic to remote once we're bigger, but we have an enormous mandate, and I want us to tackle it like an RPG final boss in the trenches together. We have a lot to build and prove and learn. Doing it together in person reduces the network hop effects and leads to more serendipity and exchange.
In a years' time, I want us to have built open source alternatives to large portions of the most used software. I want us to create a considerable shake up. I want us to have built new infrastructure to make the web more distributed and more P2P.
I think we stand a better chance if we're in a room together, hacking and engineering together. That's what my gut tells me.
I make films too, and that's frankly something that could never be fully remote.

This could really take off if the leadership can demonstrate remote-native work patterns. The on-site requirement is low oxygen.

Estuary | US-Based / Remote | Full-time – https://estuary.dev/
Estuary is a VC-backed, post–Series A startup powering real-time data replication and transform — from sub-second CDC replication to terabyte-scale OLAP data flows. We’re open-source, developer-first, and focused on making data movement radically simpler across both our Platform and Applications layers.
We’re hiring for:
Head of Engineering — Own the engineering function end-to-end as a partner to our founder CTO: strategy, people, delivery, and operations across a compact but high-leverage team. You’ll grow the leaders already running our teams, set technical strategy jointly with the CTO, and be accountable for what engineering ships and what it costs.
Senior Systems Engineer (Control & Data Plane) — Build the high-performance backbone of our platform: the orchestration, distributed state, and stream transport that keep pipelines at sub-second latency under massive throughput. You’ll work primarily in Rust on fault tolerance, consensus, and networking, and help set the bar for correctness and performance across the team.
Product Manager — Own product areas end-to-end, working closely with engineering and design to shape the roadmap and deliver a great developer experience. Engage with users, translate real-world use cases into product decisions, and help define how modern data infrastructure should feel to build with.
Head of Product Marketing — Lead product marketing as we bring real-time, agent-ready data pipelines to technical buyers, partnering closely with our Head of Marketing, Developer Relations, and the founders. Own positioning, messaging, launches, and competitive narrative, turning what our engineers ship into stories data teams actually care about.
Solutions Engineer — Partner with sales and customers from the first technical call through production, running discovery, demos, and proofs of concept for data engineering and platform teams. You’ll design CDC, streaming, and batch pipelines on Estuary, solve real integration problems hands-on, and feed what you learn back to Product and Engineering.
Customer Success Manager — Own the post-sale relationship for our data engineering and platform customers as our first CS hire. You’ll build onboarding, account health monitoring, and the expansion playbook from scratch while staying technical enough to resolve most issues yourself.
Senior Compliance Engineer — Own our GDPR and PCI DSS programs while keeping our audited SOC 2 and HIPAA programs running smoothly, alongside hands-on ownership of identity, endpoint, and SaaS estate management. This is a governance-first role for someone who has run a compliance program end-to-end, not just contributed to one.
What we’re looking for: People who care about building reliable, maintainable systems and processes and enjoy working with complex APIs, data flows, or customer relationships. We value curiosity, clear communication, and a willingness to learn.
Bonus points for experience with CDC tools, open source contributions, or fast-paced startups.

MixRank (YC S11) | Software Engineers | 100% Remote (Global) | Full-Time MixRank processes petabytes of data every month through web crawling. Hundreds of customers use our data products, including Google, Amazon, Facebook, Intel, and Adobe, across industries such as finance, recruiting, sales, marketing, and security. We’re a fully remote company with a global footprint across 20+ countries. We’re growing, profitable, employee-owned, and have no dependence on outside funding. Applicants from all geographies and backgrounds are welcome. We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely love to do. We’re obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team. Our codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two minutes.Effectively all of our codebase is written in Python, Rust, SQL, JavaScript/TypeScript, and Nix. The core technologies you’ll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git. We operate at a larger scale than typical startups. We run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.
Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests. Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.

Don't Use This Code: https://dutc.io | Training & Consulting | Full-Time (W-2) | Fully Remote (US-only)
Don't Use This Code's mission statement grew out of a joke… let's look at something amazing that will change the way you think about this programming language feature or this open source library… just DON'T USE THIS CODE.
I (the poster of this) made a little of a name for myself in the Python community through this very approach. See: https://pyvideo.org/speaker/james-powell.html or https://www.youtube.com/@dutctv or https://www.youtube.com/@PyDataTV/search?query=james%20powel...
The core principle is: true expertise and expert knowledge is worthwhile to develop and disseminate (and this is true even if the LLM is doing a lot of the typing.) To this end, our goal is to deliver a combination of training, consulting, and hybrid coaching services to clients in the tech industry, in financial services, and at large-scale scientific research facilities. In fact, on the back of some recent successes, we are gearing up to build up a team and dramatically expand this work. Our work involves a lot of data analysis, data visualization, modelling, simulation, and experiment tooling system and infrastructure, and is currently very Python and PyData heavy.
We are looking to hire both junior and senior technical leads, as well as instructors.
We're just beginning to ramp up our hiring process, but provisional job reqs are available:
- Senior Tech Lead: https://docs.google.com/document/d/1_uJdBJlGmin4gQ_9kxxFS7cH...
- Junior Tech Lead: https://docs.google.com/document/d/1_uJdBJlGmin4gQ_9kxxFS7cH...
- Instructor: https://docs.google.com/document/d/1_uJdBJlGmin4gQ_9kxxFS7cH...
Given the nature of our clients, we are especially fond of hiring people with background in the sciences, including those in fields like biology or psychology, who have a strong (perhaps even self-taught) technical background.
E-mail with your résumé or LinkedIn and add any thoughts you have on developing and sharing expert knowledge: jobs@dutc.io

Railway | Senior Growth Marketer, Senior Product Marketer, Account Executive, Scale, Senior Product Eng (full-stack) | REMOTE (Worldwide) | https://railway.com/careers
Do you feel scared and alone when opening the AWS console? Do you wish you could just tell Claude to manage your infra, and it would just work? Do you dream of a future where software is abundant and developers and normies alike are free to build their wildest dreams?
We're Railway, and we think infrastructure can be better. We're working at the forefront distributed systems engineering, interface design, and agentic computing to bring about the infrastructure platform we've always wanted. So far we've built out a platform loved by 4M+ users and we're just getting started.
Fair warning! The problems are complex: racking and stacking servers, home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.
