Qualifications
- Solid expertise in full-stack development — or proven ability to learn quickly and independently: TypeScript (consistently, no JavaScript), Next.js (App Router) / React, Tailwind CSS, ideally shadcn/ui, PostgreSQL with Prisma (and pgvector).
- Genuine self-motivation: You see open ends and address them instead of waiting for instructions.
- Persistence: You stick with a difficult bug or an unclear requirement until you truly understand it.
- Enjoyment of independent learning - also with modern AI coding tools like Claude Code, which are part of our daily routine.
- UX affinity is a plus - you pay attention to meaningful interfaces and clear user guidance.

- Bonus, not required: Clerk, Langfuse, PostHog, Microsoft Graph API, MCP, Marker.io, Linear, Google Cloud.
- Very good knowledge of German or a serious willingness to familiarize yourself with German.
Experience
- Work experience is not a filter for us - whether you're a beginner or experienced. What matters are skills, curiosity, and the drive to immerse yourself in an AI product.
- Interest in or initial experience with AI technologies - LLMs, Prompt Engineering, RAG - and the motivation to bring this into real product features.
- Experience with API integrations and auth flows is a clear plus.
