We work together but you plan your own day and choose your own way of working that suits your productivity best. We like to enjoy our time spent at the office, so we value the importance of balancing hard work with time for small breaks, relaxing and socializing with colleagues, and having fun.

We have an office filled with zones, such as fun zones with table football, a pool table, darts, and table tennis, or enjoy some time in one of our many relaxing zones. If you feel like it, why not start or end the day by spending time in our very own gym?
Every day starts with breakfast and lunch is prepared by our very own chef, serving us a nice, delicious lunch.

  • An entrepreneurial and dynamic work environment where you can make a difference.
  • Attractive pension plan, health insurance, dental insurance, massage at the office, and free flu jabs.
