eBay is a global commerce leader that connects millions of buyers and sellers around the world. We empower people and create economic opportunities for individuals, businesses, and communities. We're driven by a vision to create a more sustainable form of commerce that benefits the environment and society as a whole.

The Cloud Data Technologies (CDT) team at eBay is responsible for all the data infrastructure and management of end-to-end data lifecycle for all eBay data from onsite to analytics use cases. We are looking for strong backend infrastructure engineers who are passionate about building data systems that support our real‑time, batch and AI systems.

We are seeking a Senior MTS Software Engineer to lead the architectural vision and technical strategy for eBay’s Core Data platform organization.

We are seeking Data Platform Software Engineers, not Data Engineers. While familiarity with Spark, Flink, and other tools in the Hadoop ecosystem is an advantage, your focus will be on building the data platform rather than just creating data pipelines.
