What we offer

We have a clear commitment to quality and continuously improve our way of working.
Technically, we rely on the following technologies and standards, among others:
React and TypeScript,
Redux and RTK for structured state management,
RTK Query for data fetching and caching,
Zod for validation and robust data models,
REST and GraphQL APIs with clear interfaces,
Vite for fast development workflows,
Vitest for unit and integration testing,
Playwright for End-to-End Testing,
Emotion for CSS styling.
Furthermore, we already have established engineering building blocks that we deliberately build upon, e.g.
GitLab CI with reusable pipeline components,
ESLint and Prettier for linting and formatting,
Docker and Kubernetes for containerization and deployment,
Logging and Monitoring with Prometheus and Grafana,
Matomo for product-related analytics.
Of course, we also offer the classic benefits, including flexible working hours, modern workplaces, JobRad, Hansefit, as well as team events and activities.
