Senior Performance Engineer - Apple Frameworks

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.Analyze, identify, and resolve intricate performance challenges Collaborate with other 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 confidence within the team. Conduct and share research on the latest trends and best practices to achieve performance objectives across various dimensions, including memory, CPU, GPU, power consumption, and launch times. BS in Computer Science or equivalent. 5+ years of experience developing performance-critical software, with a solid understanding of systems architecture, modern frameworks and their performance characteristics for mobile applications. UI development for iOS, macOS, watchOS or other Native Platforms. Experience using various profiling tools, (e.g. Xcode Instruments, Android Studio Profiler, VTune, or other proprietary tools) to identify and resolve performance bottlenecks affecting the UI, CPU, GPU, memory, and system power. Proficiency in performance analysis, debugging, and code optimization techniques to enhance application and user interface performance. Proven ability to collaborate effectively with a diverse team and thrive in fast-paced, deadline-driven environments. Effective communication of intricate performance analysis to diverse stakeholders, including actionable recommendations.Experience optimizing performance across various domains on multiple platforms (e.g. iOS, Android, or Desktop). Knowledge of power management and battery-life analysis techniques. Experience with Mac or iOS application development using Swift/Swift-UI or Objective-C. Experience with Metal or modern graphics APIs (DirectX, Vulkan).
