The Role & The Team

Lounge by Zalando is the fastest-growing segment of Zalando, boasting billions of euros in annual turnover. Despite this success, there remains significant untapped potential in personalization and recommendation.

As a Senior Data Engineer, you will lead the effort to build a large-scale recommender system. As Europe's largest online fashion retailer, we require an exceptional engineer capable of creating Machine Learning pipelines in Spark on a global scale. Your responsibilities will encompass everything from batch/stream preprocessing, model training, and model/feature distribution to the real-time recommender system.

You will have full autonomy in making architectural decisions and implementing state-of-the-art ML recommender algorithms. Few roles offer such a unique combination of scale and ML complexity.
