Our expectations of you
Qualifications

- Backend core (what we expect): NestJS with TypeScript/JavaScript (Node.js), PostgreSQL: data modeling, migrations, query tuning, RabbitMQ and asynchronous, event-driven communication, WebSockets for real-time features, REST and API design, testing as part of our Definition of Done, not in rework, CI/CD, Git, Docker, agile working.
- Frontend (what we expect): Angular with TypeScript.
- It is important that you are confident on both sides and can quickly get familiar with new stacks. For the core technologies mentioned, we expect several completed projects that you can showcase in your CV.
- The project language is German.
- You work in the client's team, in German, during meetings and in documentation. We expect German at native speaker level or a C2 certificate.
- AI tools are mandatory, not a bonus. Claude Code, Copilot, Cursor: you need to be able to work productively with them. Not because we want to be trendy, but because our clients expect it and we work that way. If you think AI tools are just a hype and prefer to type everything yourself: wrong company. Internally, we invest in your AI skills.
