THE ROLE AND THE TEAM

Our ML Platform team builds the foundational intelligence layer that powers Zalando’s AI-native experiences. We provide the infrastructure to serve low-latency features, embeddings, and real-time updates that enable applied science and product teams to deliver search, recommendations, personalization, forecasting, and emerging GenAI use cases. Today, we operate Zalando’s central Feature Store and are scaling it into a broader discovery hub for customer, product, and content understanding in real time.

As Principal Engineer, you will play a leading role in shaping technical strategy, setting engineering standards, and influencing architecture across ML infrastructure at Zalando. Partnering closely with product leadership, you will co-own the vision and roadmap for the ML Intelligence Platform, ensuring our foundations enable AI-native customer experiences at scale.
