Full-stack Product Engineer at a pre-seed Berlin healthtech startup building a preventive health platform. Requires up to 1 year of experience, full-stack capability, AI dev workflows, and eligibility to work in Germany without visa sponsorship. Salary €36,000-€48,000 plus equity.
ABOUT THE ROLE
A fast-moving, pre-seed healthtech startup building a modern preventive health platform is looking for a highly autonomous Product Engineer to join their small team in Berlin. The platform combines advanced biomarker diagnostics, clinician-reviewed health plans, AI-powered concierge experiences, and interactive customer dashboards into a single seamless product.
This is a founder-mode role — no PMs, no hand-offs, no tickets handed to you. You'll work directly with the founders, own features end-to-end, and ship real product from day one.
WHAT YOU'LL DO
- Ship product end-to-end across the web app, backend, and third-party integrations (lab partners, supplement manufacturers)
- Build and iterate on customer-facing experiences: biomarker dashboards, personalised action plans, and subscription flows
- Own and improve engineering infrastructure and AI development tooling as the product scales
- Work directly with the founding team to translate product vision into working software — fast
WHAT WE'RE LOOKING FOR
Required
- Up to 1 year of software development experience, with shipped, real-world software — startup, founder, or indie hacker contexts are a strong signal
- Hands-on experience with modern AI development workflows and tooling (e.g. Cursor, Claude Code, evals, agentic pipelines)
- Experience designing and implementing customer-facing dashboards and subscription flows for web applications
- Experience building API integrations with external partners (e.g. lab or manufacturing providers)
- Genuine full-stack capability: comfortable owning frontend, backend, and integrations without relying on specialists
- Professional working proficiency in English
- Ability to operate autonomously in a high-trust, low-process environment
Nice to Have
- Proficiency in TypeScript and Next.js (or equivalent); experience with React, PostgreSQL, Supabase, and Vercel
- Genuine interest in or background relating to preventive health, longevity, or biomarker science
COMPENSATION & BENEFITS
- Salary: €36,000 – €48,000 per year
- Early-stage equity opportunity (details discussed during interview process)
- Direct collaboration with founders and meaningful ownership over product direction
