The

Unified Feature Store (UFS)

team at eBay, part of the

Golden DataSet

Platform (GDS)

initiative, is building the next generation of eBay's AI and decisioning platform. We are developing a declarative, self-service platform that enables engineers to define, discover, compute, validate, and serve features consistently across both training and real-time inference. Our mission is to eliminate feature duplication, ensure training-serving parity, and provide reliable, scalable, and low-latency feature infrastructure that powers fraud detection, payments, search, personalization, and other mission-critical experiences across eBay. About the Role

We are seeking a

Senior Staff Software Engineer
