You will keep a good connection to other people around the agile development team, like Product Manager, Designers and Data Analyst to influence possible future features.

With your expertise, you will exert a strong influence on decisions, methods of approach and results in the team.

  • Lay the technological foundation for the global success of our products
  • Collaborate with the product owner, designers, UX researcher and localization engineers to find the best technical solutions and give feedback about the technical feasibility of new feature requests
  • Develop high-quality and highly-secure Windows desktop applications using modern methods in C#, while working in an agile scrum team to leverage the power of a self-responsible and multi-skilled team
