As a Senior Developer, you will be part of a team of 5 developers and work on the transformation of a large and complex legacy application landscape. You will help modernize existing business-critical systems and evolve towards a future-oriented and modern architecture.

  • Translate functional requirements into scalable and secure technical solutions
  • Develop and integrate REST APIs between different systems
  • Collaborate on frontend development using React and/or Blazor
  • Ensure code quality through testing, code reviews, and documentation
  • Act as a technical point of contact and coach for less experienced colleagues
  • Contribute to architecture, technical decisions, and future evolution

Profile

  • At least 7 years of experience in a .NET environment
  • Strong knowledge of .NET Core, C#, ASP.NET, Entity Framework, and React and/or Blazor
