Description

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. DESCRIPTION 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. MINIMUM QUALIFICATIONS BS in Computer Science or equivalent. 5+ years of experience developing performance-critical software, with a solid understanding of systems architecture, modern UI frameworks and their performance characteristics. 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. PREFERRED QUALIFICATIONS 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).

Responsibilities

This role involves diving deep into system architecture and UI systems to establish performance baselines, resolve complex performance issues, and build mechanisms to prevent future regressions. A major focus will be designing and implementing comprehensive, automated power and performance regression testing strategies targeting critical metrics across all platforms.
