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
