Our team is responsible for turning data into services and products for XING. 5 Data Scientists/Engineers, backed by a Frontend engineer, work together to create highly scalable solutions which serve millions of users.

We are an international team with people working from Porto, Hamburg and remote.

At the moment, we are working intensively on projects related to reusable recommender systems components, building pipelines for automated machine learning and developing products which help XING users to grow their network. For example, we are currently designing and implementing new ranking models for our contact recommender which is the main service that people use to connect with each other on XING.
