What You'll Do Design and build features across our microservices landscape, working full-stack in C# and TypeScript, from first refinement through deployment and monitoring in production.You don't just build what's asked, you push back when there's a better way. Question assumptions in refinement and architecture discussions, and speak up when you see a stronger solution.Improve our CI/CD pipelines and engineering practices, not just the code that runs through them.Use AI tools like Claude Code and GitHub Copilot in your daily workflow to work faster and sharper.Work closely with engineers across the domain to keep our systems reliable and maintainable. About The Team You join the team behind the Internet and TV services of Budget Thuis, one of the four largest energy providers in the Netherlands.

We work in OKRs and are actively shaping a new way of working, so you help decide both what we build and how we get there.
