Product Engineer
Job description
About the Role
We're a fast-moving, pre-seed healthtech startup building a modern preventive health platform — combining advanced diagnostics, biomarker-driven insights, AI-powered concierge experiences, and personalized health dashboards into one seamless product. We're looking for a highly autonomous Product Engineer to join us on-site in Berlin and help shape the product from the ground up.
This is a founder-mode role: no PMs, no hand-offs, no tickets handed down from above. You'll work directly with the founding team, own features end-to-end, and ship real product that reaches real users.
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, personalized action plans, and subscription flows
Own engineering infrastructure and AI development tooling as the team and product scale
Work directly with the founders to translate product ideas into working software, fast
Integrate external APIs from lab and manufacturer partners into a cohesive platform experience
What We're Looking For
Required:
Up to 1 year of software development experience — what matters most is that you've shipped real software, ideally in a startup, founder, or indie-hacker context
Hands-on experience with modern AI development workflows and tooling (e.g., Cursor, Claude Code, agentic workflows, evals)
Demonstrated experience designing and building customer-facing dashboards and subscription flows for web applications
Experience building integrations with external partners via APIs
Full-stack ownership mindset — comfortable across frontend, backend, and integrations
Professional working proficiency in English
Ability to operate autonomously in a fast-paced, founder-style environment
Must be eligible to work in Germany without employer visa sponsorship (no sponsorship available)
Nice to Have:
Proficiency in TypeScript and Next.js with React and PostgreSQL; familiarity with Supabase and Vercel is a plus
Genuine interest or background in preventive health, longevity, or biomarker science
Compensation & Benefits
Salary: $36,000 – $48,000 per year
Early-stage equity opportunity in a growing healthtech company
Direct collaboration with founders and a high degree of ownership from day one
Location
Berlin, Germany — fully on-site, five days per week (non-negotiable)
Visa sponsorship is not available; candidates must have existing authorization to work in Germany
