We are day-to-day working on a number of interesting engineering problems, including ingestion of large data sets, high-volume traffic sites, big data and machine learning to name a few – with many more to come.

In this role with us you will support our team in developing and improving our Ruby on Rails-based platforms, and, all of which are household names in the German Car industry, used by millions of users monthly to find the information and cars they need.
