Senior Backend Software Engineer (SCALA / Java) - Interactions Domain

Marktplaats in the Netherlands, and 2dehands and 2ememain in Belgium are part of the Adevinta* Group. The 3 brands are hosted on a multi-tenant platform, operated from our Amsterdam location and are the top players in the classifieds space throughout the Benelux region - with over 11 million monthly unique users.
