Production Engineers are software engineers who embed with product, platform, and infrastructure teams to find and fix what breaks at scale. We think of them as hunters: engineers who go looking for the anomaly, the bottleneck, the slow degradation nobody has noticed yet, and then own it through to a fix, working with whoever owns the system to make sure it stays fixed. Live video and real-time commerce run on the same critical path here. Every auction is live and money moves during the show, so system behavior and business outcomes are tightly coupled in a way few platforms experience. Milliseconds are visible to buyers and sellers, and the signals that matter most are often small, concentrated in a specific cohort, and invisible in aggregate. Surfacing them early, and knowing which ones are worth acting on, is the core of this work. Production Engineers embed with a team and go deep on its systems, while staying accountable for what falls between teams. Some of the most consequential problems at our scale live in the seams, in the interaction between two services that each look healthy on their own, so we expect hunting both inside your area and across it. You'll be joining early, which means broader discovery across the platform before the embedding settles, and real influence over how Production Engineering takes shape here.

Go deep with the team you embed with, raising the reliability, performance, and scalability of their systems alongside them and writing the code that gets it there. Hunt anomalies across traffic, latency, error, and cost signals, both inside your area and in the seams between teams, and trace them to root cause across services, storage, and clients.
