How do we develop software?

Each team works on their own part of the software. These may be customer-oriented components, but also our warehouse system, or our own HR system. You develop, optimize and implement new features. All systems we are working on are developed by our own teams, so that we can respond to complex and challenging changes in the marketplace. Even though we also use the systems ourselves, we create it as stand-alone software that is of value to other companies. So even though we are also a webshop, we consider ourselves to be a software company. Our scope is a lot broader than you might have expected.

Our stack


... and don't forget Gitlab, Docker, Typescript and Redis. We use various tools, including Jetbrains, Slack, Ubuntu/Windows and vscode. This is always in motion, as the world of technology never stands still either.

What will you do as a Software Engineer?

  • You help us translate our business objectives into well-working software.
  • You help us build leading telecom software.
  • You get responsibility for your part of the code.
  • You think along about the scalability and architecture of the software.
  • You get our trust to make your own technical choices.

What can you expect from us?
