Who we are

We operate the international online marketplaces of Kaufland: Several thousand sellers and millions of products make us one of the fastest growing online marketplaces. Ours is a dynamic corporate culture that merges a start-up mentality with the opportunities offered by a large corporation. We combine knowledge and many years of experience in e-commerce with flat hierarchies and a highly motivated team.

We love flexibility! We offer you the best environment to work in a flexible and focussed way: You get to decide whether you want to work in one of our offices in Cologne // Darmstadt // Düsseldorf, but also have the opportunity to work remotely (within Germany) and choose the best of both. We want to offer you the most attractive workplace in e-commerce and maximum flexibility for your personal work-life balance.

Day by day, our development team of about 400 experts pursues the goal of creating the best possible customer shopping experience for our online marketplace.
