In cooperation with the UX team, you will also discuss design concepts for technical implementation and help to create optimal solutions for new features, interaction elements and technical components. You will work closely with backend developers, designers and editors to find the best technical and most user-friendly solution.

In the midst of the COVID-19 pandemic your health is our top priority. As such, we developed a hygiene concept for the office, which enables us to partly work together in small groups. This safe and socially distant way of working allows us to create a low-risk work environment that complies with social distancing regulations.
