Product Engineer (w/m/d)

• Build 0→1 and beyond with the founders: Ship major features and product lines end-to-end (spec → ship → measure).
• Core Architecture: Design and implement the APIs, data models and services that the product runs on — and ship the UI on top of them. Pragmatic architecture choices with high autonomy.
• Iterate fast: Ship v1 fast, iterate weekly with real user feedback.
• Leadership: Hire and mentor junior engineers (if interested); gain leadership experience as we grow.

• 5+ years of professional experience building and operating web applications end-to-end, with strong TypeScript/Node fundamentals (Next.js, FastAPI, or comparable server frameworks; React on the frontend)
• A bachelor’s or master’s degree in computer science or a related field
• You have worked in a cross-functional team setup, are product-minded and like working in an agile startup environment
• Your centre of gravity is the backend – APIs, data modelling, integrations — and you're comfortable owning a feature through to the UI. Balanced full-stack profiles are equally welcome; what matters is that you can go deep on the server side.
• You have experience in deploying applications using containerization and orchestration tools (such as Docker)
• You have integrated AI already deeply into your daily coding tasks and don’t just use it for autocompletion
• Very good written and verbal communication skills in English (min. C1), German is a plus
• You have a valid work permit to work in Germany

• Prefer boring tech where it matters; innovate where it differentiates.
• Current stack (continually evolving): TypeScript end-to-end, Next.js (React) with server-side APIs, PostgreSQL, Vercel, …
• Most of the hard problems sit behind the API: data modelling for tax logic, integrations with third-party systems, and AI pipelines that have to be correct, not just plausible.
• You’ll have a strong influence on tech and product choices.
• Tooling budget for whatever makes you fast. No legacy, no yak‑shaving.

• Jump on an intro call with a recruiter
• Get to know a fellow engineer, virtually or in person (up to you)
• Meet our whole founding team during a final interview (in-person, ~3h, incl. live coding)

• Unique opportunity to join a company very early which you can shape
• Rapid growth path: Grow your career with the growing company
• Perfect environment to develop relevant skills in a world of AI
• Above-market compensation + Equity package, that has the potential to drastically gain in value
