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.

Come help us build explainable AI for providing physiotherapy at scale.
Our core systems are a custom decision engine, interactive streaming video over WebRTC, and multiple internal tools to help us scale. We care a ton about high quality software and great UX - healthcare apps has a bad rep for being unpolished. Commercially, we partner with national healthcare systems to provide high quality care that patients love.
Over the next 18-24 months we are expanding our geographical and product footprint:
- Our infrastructure will need to mature - Our software will need to generalise as we treat more clinical conditions - Our collection of internal tools will need to grow
We're hiring for generalist engineers. Our core stack is Python/Rust/Typescript, but all backgrounds welcome as long as you like ownership and responsibility.
Read more and apply at https://www.flok.health/careers/engineering-team or find me online and DM me! We're 4 days a week on-site in a beautiful farm-style office in Cambridgeshire.
Definitely mention you came from HN if you apply - will help you stand out against the flood of AI-generated applications we get these days.
We're ~160 people, fully remote, building an AI marketing platform. Our main product is OTTO, which runs a site's SEO on its own - it reads live search data and pushes the technical and on-page fixes itself, nobody queues them up. Around that we've got ad automation for Google and Meta, GBP management for multi-location brands, content gen, and LLM visibility tracking (whether ChatGPT and co are citing you). Autotrader, Hyundai, P&G, Vendasta are some of our customers.
Work happens in pods, 1 PM and 2-4 engineers. You own your pod's roadmap and ship it with them, no veteran PM signing off on your specs first. That's the part most PM roles won't hand you.
Looking for 3+ years PM in B2B SaaS with an actual technical background - eng or QA before PM, or a PM who's been getting into the codebase themselves. You should be able to read Python and TS, write your own SQL, find your way around an API, and not need an engineer to tell you what a stack trace says. We're Django on the back, React/Next on the front. QA is yours end to end including release sign-off, people tend to underestimate that bit. And you're already using Claude Code or similar daily, not "open to it".
A few notes before you apply:
- Experience: we're looking for people with a few years of hands-on product or engineering work behind them. The role is autonomous from the first week, so we need you ready to take the wheel. - Recruiting agencies: we hire in-house and manage every application ourselves, so there's no need to send candidates or reach out about partnerships. Thank you for understanding! - If your stack matches, please do reach out. Django/DRF/Celery/Postgres with React/Next, Python automation work around SEO: if that's your day-to-day and you're using AI coding tools (Claude Code, Codex, Cursor, whatever you like) in your real workflow, I want to hear from you. Don't talk yourself out of it because the title isn't an exact fit; tell me what you've built.
Recruitment process is screen with me, a take-home that runs about 75 mins, technical round with one of our senior PMs, then a call with our Director of Product (who you'd report to). I usually come back to people within 2 business days.
Our ATS forces us to list specific ywhere as long as you can do EST hours, so apply even if yours isn't
Apply at the link and mention HN somewhere, in your pitch or wherever it fits. joao.pedro@searchatlas.com if you need me, though the link's faster.
P.S: Not a PM, or the PM role isn't quite your thing? Have a look at everything else we have open at https://careers.searchatlas.com and apply directly to the role that suits you best (preferred route). If you're not sure which one that is, email me with a short line on what you do and I'll point you to the right one.
Lokker is a privacy platform. We continuously analyze websites, applications, third-party technologies and data flows to identify privacy, security and consent risks in production. We have built a large proprietary dataset from years of observing real-world digital behavior, and we are hiring a data scientist to help us expand and improve the classification, scoring and risk intelligence built on it.
You will develop and improve models that classify digital activity, identify meaningful privacy and security behaviors, and assess the confidence and significance of findings.
Looking for 2 to 4 years of production experience in data science and machine learning. Strong Python and SQL, pandas or Polars, scikit-learn and modern classification techniques, familiarity with model evaluation and explainability. Practical experience in training and evaluating supervised classification models on real PRODUCTION data, practical LLM experience beyond simple demonstrations, and curiosity about how websites and internet technologies actually behave. You do not need a privacy or adtech background. We will teach the domain.
You will work closely with engineering, product and privacy experts, and what you build goes directly into the product.
IMPORTANT: the timezone range above is a hard requirement, not a preference. We cannot make an exception.
ON APPLICATIONS: we assume you used AI to help write it. So do we. What we cannot do is verify a claim that exists only in the document you sent us, so make sure the skills you claim are visible somewhere public: LinkedIn with real dates and role detail, GitHub, papers, Kaggle, a writeup, a talk. If your best work is under NDA, say so and describe it in your own words.
A human reads every application. No keyword filter, no automated rejection.

We build high-throughput crawling and structured data extraction infra designed for AI agents and LLM pipelines.
If you’ve built scrapers recently, you already know the state of the market:
- Traditional proxy providers (Bright Data, Oxylabs, Smartproxy, Proxybase) give you raw IPs or massive unparsed HTML blobs, leaving you to deal with DOM bloat, token waste, and brittle parsing pipelines.
- Modern tools like Firecrawl or Jina made clean Markdown extraction easy for hobby setups, but they often struggle when you throw heavy SPAs, high-concurrency jobs, or hardened anti-bot walls (Cloudflare Under-Attack / Turnstile, Kasada, DataDome) at them.
- Rolling your own Playwright / Puppeteer cluster works until target sites deploy new JA4/TLS fingerprints, and your data team ends up spending 30% of their sprints fixing broken crawlers instead of shipping product.
We're tackling this by combining a low-latency Rust fast-fetch engine (JA4/TLS and HTTP/2 frame emulation) with an isolated stealth browser fleet, zero-code schema validation (JSON Schema/Pydantic), and native Model Context Protocol (MCP) support.
Trade-offs / where we fit: If you just need to curl a few static Wikipedia pages, a 10-line Python script is better and cheaper. But if you need reliable, structured data out of bot-defended sites without babying headless browsers, that's what we do.
We're looking for:
1. Rust Systems Engineer: High-concurrency network I/O, Axum/Tokio, TLS/BoringSSL fingerprinting, proxy routing matrices, and low-latency data pipelines.
2. Browser Security Engineer: Deep familiarity with browser internals (Firefox/Chromium source), canvas/WebGL/audio fingerprint evasion, CDP/WebDriver stealth, and familarity with anti-bot defenses.
Our stack: Rust, Next.js 16/React 19, TypeScript, hardened Firefox/dwx_crawler, Linux/Xvfb, SQLite WAL/Postgres.

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.

I'm Yarik, cofounder and CTO. Before this I spent 20 years in tech with 10+ years running infra, ML and search teams at Google, Meta and Apple.
We love maps and build location/businesses APIs for AI apps and agents. If ChatGPT tells you a restaurant is open and it actually closed in March, that's the problem we fix. We check whether a business still exists, whether its hours and details are right, and enrich it with what's being written about it on the web (news, articles, events). Customers get all of it through one API and we solve it for them with our models which use all available sources and ai voice agents which can confirm the information.
You'd be one of the first engineers. Some weeks that's search and ranking, some weeks it's data pipelines or evals, some weeks it's the API or something a customer asked for yesterday. You'll have a big say in what gets built, not just how.
Stack: Python, FastAPI, Postgres/PostGIS, DynamoDB, Redis, AWS (EKS), our own ML models plus LLM APIs (OpenAI, Gemini, Anthropic).
What I'm looking for: - 2+ years shipping production systems, or fewer if your background is unusual and you can show what you've built - real experience with at least one of: search/IR, large-scale data processing, ML systems, API design - you already use Claude Code, Cursor or similar as part of how you work - geo/POI data experience is a plus, not required
Fair warning: we are a small team, fast pace, and there could be nights and weekends. If that's not where you are in life right now, totally fine, this just isn't a good fit.
Process: a short note on why you, a 30 min call with me and then Vlad, a technical deep dive, then a paid trial project.

Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here.
We are hiring a Senior Software Engineer to join the Application Security team. This is hands-on product engineering: building security features that protect user accounts, strengthening authentication and session security, and improving security-critical services. You will work directly with product teams to ship user-facing account security tools and address emerging threats.
Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.
Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and writing code across languages, experience shipping production software, and sound judgment on prioritizing real risk over checklist security. Experience with authentication, passkeys, MFA, or session management is especially relevant.
Location: Remote from the US West Coast. If you are in the Bay Area, our SF office is an option. Relocation to the Bay Area is not required.
Interview process: recruiter call, coding round, HM interview, virtual onsite, decision.

Join us at Snout on our mission to ensure no one ever has to make a health decision for their pet based on the cash in their bank account. Snout plans pay for 100% of routine veterinary care, unlimited visits, and additional member benefits - think pet insurance, that you will actually use every year.
We're growing the team and hiring across the board. Featured role this month:
Founding Data Engineer - be our first data hire: make sense of hundreds of millions of rows from vet practice-management systems and our own app, and turn our Postgres and dbt warehouse into a foundation the whole company trusts.
Our tech stack includes Node.js, React, PostgreSQL, AWS, Tailwind, and Python. We use both JavaScript and TypeScript heavily. Our team uses LLM-based tooling day to day, but we're fundamentally a human-centric team, and our product itself does not heavily feature AI components.

E-mail jobs[at]openeducation.foundation met (HN) + de functienaam in het onderwerp, samen met een korte introductie en een link naar je LinkedIn-profiel en/of GitHub. Als er van beide kanten een goede match lijkt te zijn, plan ik graag een kennismakingsgesprek in.
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. We expect you to have a real, current AI-assisted development practice. Our system spans several languages, and we expect you to use AI tools to quickly navigate unfamiliar parts of the codebase so you can comfortably own problems end-to-end across a broad stack.
We are hiring for three roles:
- Senior Software Engineer: You will work across our event-driven architecture. You'll write Go and Python backend services and touch endpoint-deployed browser and desktop components. You need to be comfortable developing in a multi-tenant, microservice-driven SaaS architecture and understand typical scale and security implications for such products.
- R&D Engineer: This is not an open-ended research function. You will take ambiguous feasibility questions tied to our roadmap and return defensible answers inside a week. You'll build handoff-ready prototypes, then shift into engineering mode to personally drive them through to production. You will also define operational envelopes and degradation boundaries, and rigorously deprecate infeasible ideas with documented rationale to avoid future re-litigation.
- Intelligence and Data Processing Engineer: This role is for someone who loves real browser and desktop forensics. You'll use dev tools and debuggers as your primary instruments. Expect to be reading minified code to find where state lives and analyzing network logs to understand undocumented APIs. You will figure out how AI products work and build the prototyping and automation to maintain our software inventory.
To apply: Send an email to eric+hn@sidekicklabs.com with the role in the subject. Include a PDF of your resume, a quick sentence or two about a tough technical problem you've solved recently, and links to your GitHub, personal site, and/or LinkedIn.
I'm Eric, VP of Technology, and I will personally read every email sent to the HN subaddress. You can view my background here: https://www.linkedin.com/in/three-two-one
