  • The freedom to embrace small-scale failures as a path to large-scale success.
  • The belief that factual proof, not seniority, determines which path to take.

  • Being supported in all your needs, including relocation assistance and language classes for international arrivals.
  • The opportunity to develop personally and professionally with regular free code workshops and Hackathons, as well as the chance to contribute to our tech blog.
  • Living in Düsseldorf, a city boasting the 6th highest quality of life in the world for expats.
