About this role

Senior Software Engineer - UI and Performance Cupertino, United States of America Our 3D Graphics Team is looking for a Senior UI Engineer with a balanced focus on system and UI 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. Analyze, identify, and resolve intricate performance challenges within the Maps client, particularly focusing on UI-specific issues. Collaborate with UI engineering teams to explore product architecture, pinpoint bottlenecks, and propose practical performance improvements. Address performance regressions arising from cross-domain interactions between UI, Rendering, and System components (e.g., UIKit, CoreAnimation, Metal, etc.). Lead efforts to establish a reliable performance test automation infrastructure, thereby fostering confidence in the accuracy and reliability of test outcomes. Develop tools that provide clear, actionable insights across performance domains, fostering
