Your role in the team
- You work on client projects for large companies and public-sector clients, embedded in their teams and with full responsibility for your area.
- Full-stack development with TypeScript: Node.js on the backend, Angular on the frontend.
- Integrating language models into specialized applications: RAG, tool calling, and agents running in production.
- Help shape the architecture, not just implement it.
- Generate, review, and refactor code with Claude Code, Copilot, or Cursor.
- Code reviews and technical mentoring within the team.
- Coordination with Product Owners, UX, and DevOps.
Our expectations of you
Qualifications
- Senior-level. Our clients need people who can deliver from day one and work independently.
- TypeScript on both sides, with at least three years of project experience.
- Node.js on the backend (NestJS or Express), REST and API design, PostgreSQL.
- Angular (if you come from React or Vue and feel confident working with Angular, apply anyway—just mention it in the questions).
- At least one application in which you have integrated a language model: RAG, tool calling, an MCP server, or agents.
- For us, tests are part of the Definition of Done, not an afterthought.
- CI/CD (GitLab CI, GitHub Actions), Git, Docker, agile working.
Experience
- Nice to have (not required): Kubernetes/Helm, AWS or Azure, Kafka or RabbitMQ, WebSockets, monitoring (Grafana, Prometheus), frontend testing (Jest, Playwright, Cypress), accessibility (BITV 2.0 / WCAG AA), DevSecOps / security by design, experience in the rail, public sector, or social insurance industries.
What we offer
- Our clients staff these projects almost exclusively with permanent employees. That’s why we’re looking for you for a permanent position.
- The project language is German.
- You will work in the customer’s team, using German in meetings and documentation. We expect German proficiency at C1 level or higher.
- AI tools are a must, not a bonus. Claude Code, Copilot, Cursor: You need to be able to use them productively. Not because we want to be trendy, but because our customers expect it—and that’s how we work, too. We invest in your AI skills internally.
- Work from home, the office, or a mix of both—you decide.
- MacBook (unless the customer provides their own hardware).
- Different clients, different projects.
- The founders are your direct points of contact.
- Internal upskilling in AI development.
