About The Position

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.

Requirements

• 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

Nice To Haves

• 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
