About the role

  • Develop and evolve backend services and APIs using C# and .NET
  • Design and implement REST interfaces
  • Work with relational databases (e.g., PostgreSQL, MS SQL)

  • Possibly contribute to UI components in the .NET ecosystem (e.g., ASP.NET MVC, Blazor)
  • Analyze and sustainably resolve bugs and performance issues
  • Maintain and further develop established codebases
  • Identify technical debt and make well-founded assessments of when refactoring is sensible and when it is not
  • End-to-end responsibility for your services (deployments, monitoring, troubleshooting) — without on-call duty

  • Comfortable using AI tools to support the day-to-day development workflow
  • Experience with message brokers (e.g., RabbitMQ), Blazor, or MVC is a plus but not required
  • Some exposure to Docker, CI/CD, or Kubernetes is an advantage
  • Understanding of Clean Code, maintainable architectures, and automated testing
  • Ability to navigate existing codebases confidently and independently
  • Experience in product-facing environments (e.g., FinTech, platforms, SaaS) is a plus
Benefits

  • Regular after-work and team events
  • Daily free fresh lunch, drinks, brain food, as well as fruit and vegetables
