That is why we need your help; we want to expand our team by introducing even more expert knowledge. You will work in product driven innovation teams in which front-end developers, back-end developers, a designer, a data analyst, and a product owner all work closely together. We are driven by A/B-testing and automated testing, which allows us to do multiple releases per day on our high-traffic website.

What we offer

Additionally, you can expect:
