About the Team

The eBay Auctions engineering team is on a multi-year journey to modernize one of eBay’s most iconic commerce experiences: auctions. Our mission is to bring the thrill of the game back to auction by building a real-time, trusted, and scalable platform that powers curated discovery, vibrant community, and fair bid play - where each item’s true market value can win out.

This role sits at the heart of that transformation.

You will help build and evolve eBay’s next-generation auctions platform, a real-time, highly available backend system that powers both eBay Live Auctions and traditional auction experiences. This is a latency-sensitive, large-scale commerce platform where correctness, resiliency, scalability, and customer trust are critical.

We are looking for a Senior Software Engineer who brings strong ownership, solid distributed-systems knowledge, customer empathy, and a passion for improving how teams deliver. You will independently drive meaningful projects end to end, collaborate across teams, challenge assumptions respectfully, and help the team increase engineering velocity through better design, testing, automation, observability, and thoughtful AI adoption.

What You’ll Do

• Build and operate scalable, low-latency backend systems that power eBay’s next-generation auctions platform.

• Own features and services end to end, from design through launch, observability, and production support.
