Our expectations of you

Qualifications

  • Go & API Enthusiast: You are proficient in Go (Golang) or a comparable modern backend language and have deep expertise in REST API design and microservice architecture.
  • Cloud Affinity: Basic knowledge of Docker and Kubernetes is a plus, as you work in a “You build it, you run it” environment and can deploy your containers yourself.
  • Problem-Solver: Complex UI logic or asynchronous data streams don't make you sweat—your analytical skills help you find elegant solutions.
  • Team player: You’re a communication pro and enjoy working agilely in a team that pushes one another.
  • Communication: English (spoken and written) is essential, as we operate internationally. German is a plus.

Experience

  • Backend or Full-Stack Engineer: You have several years of professional software engineering experience, primarily focused on backend development (Go, microservices, API design) or full-stack development.
  • Frontend experience (optional / a plus): Knowledge of Angular, TypeScript, and modern web architectures is a major plus for full-stack profiles, though optional for pure backend specialists.
  • Tooling Pro: You are familiar with build tools (Webpack, NX), package managers (npm, yarn), and have experience setting up CI/CD pipelines (e.g., with GitHub Actions or Azure DevOps) for frontend deployments.
