About The Position

Our 3D Graphics Team is looking for a Senior Performance Engineer with a balanced focus on system and performance to join our team. In this role, you will dive deep into our system architecture and user interface systems, establish performance baselines, solve complex performance issues, and build the mechanisms which prevent regressions before they happen. As a hands-on and collaborative performance engineer on our team, you will be equally focused on identifying, diagnosing, and resolving complex performance issues across our applications, systems, and user-interface layers. A major part of your goals will also involve designing and implementing a comprehensive, automated power and performance regression testing strategy, targeting critical metrics like frame rate, latency, memory, power efficiency, and overall system responsiveness across all platforms. In this role, you will partner with other performance and client engineers, cross-functionally providing the critical data and insights that guide our engineering teams to craft efficient, responsive, and visually appealing experiences.
