Responsibilities:
- 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

- Contribute to technical decisions within the team with a focus on maintainability and operability
- Share knowledge and work closely within a small, autonomous team
Requirements:
- Several years of experience as a software developer with C#/.NET
- Strong skills in object-oriented software development
- Experience with ASP.NET Core and OR mappers such as Entity Framework
- Confident handling of relational databases
- Experience designing and consuming REST APIs
- Willingness to work in established .NET codebases (e.g., .NET 4.8) and modernize them incrementally
- 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:
- Company pension scheme and 30 days of vacation per year (based on a 5-day workweek)
- Regular after-work and team events
- Daily free fresh lunch, drinks, brain food, as well as fruit and vegetables
