Back-End Developer (.NET / TDD / CI/CD)

You’ll join a modern Agile product organisation where teams build and maintain applications that handle complex data exchanges and long-term digital services. You’ll work alongside analysts, developers, testers, and product teams to create high-quality backend components that are stable, secure, and easy to maintain.

If you enjoy solving technical problems, working in a self-steering team, and delivering clean, reliable code through TDD and CI/CD practices, this role is a strong match.

What You’ll Do

• You turn functional analyses into solid technical specifications and collaborate closely with analysts to validate and refine solution designs.
• You build new features, improve existing components, and help resolve issues as part of second-line support.
• Quality matters  so you’ll contribute to test-driven development, automated pipelines, and clean code principles that make the product more robust with every iteration.
• You’ll also help reduce bug-resolution time and actively support your team with creative ideas and a positive, collaborative mindset.
  

What are we looking for?

• You’re a confirmed Back-End Developer with strong experience in the .NET Core ecosystem.
• You feel at ease working in TDD setups and know how to build and maintain CI/CD pipelines.
• You work confidently with Azure DevOps, YAML-based pipelines, Visual Studio, and you can handle SQL queries when needed.
• You’re comfortable in Agile Scrum teams, understand how to collaborate in short iterations, and you contribute actively to team quality and delivery rhythm.
• Language is important in this environment: your mother tongue is Dutch or French, and you can easily read and understand the other national language.
• A relevant degree in IT or equivalent experience is expected.
