Our ML Platform team builds the foundational intelligence layer that powers Zalando’s AI-native experiences. We provide 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 a Senior Software Engineer (ML Platform), you will play a key role in designing, building, and scaling these core ML infrastructure services. You’ll work hands-on with distributed systems, streaming pipelines, and feature platforms, while also mentoring peers and contributing to engineering best practices across the team.
