Founding Engineer (w/m/d)

While we are providing a world-class professional service to our customers, technology is at our core and you will be an integral part of building it from scratch. Your work will be the driving force behind our revolutionary customer experience, enabled through AI, offering radical simplicity to our customers.

Aufgaben

What you’ll own

• 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.

Our tech context (greenfield)

• 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.

Qualifikation

What you’ll bring

• 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

Benefits

What you’ll get

• 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

The process (fast, meaningful, no homework)

• 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)
