GPU Performance Engineer

Santa Clara Valley (Cupertino), California, United States
Software and Services


Posted: Jan 7, 2019
Weekly Hours: 40
Role Number: 200023030
Our responsibilities encompass the frameworks, developer tools, and device drivers for the GPU and Display on all Apple hardware. This team announced Metal 2 which provides near-direct access to the graphics processing unit (GPU), enabling you to improve the graphics and compute potential of apps on iOS, macOS, watchOS, and tvOS. Building upon an efficient low-overhead architecture with pre compiled shaders, fine-grained resource control, and multithreading support, Metal 2 further boosts performance by enabling the GPU to take more control of the rendering pipeline. Moving beyond just graphics, Metal 2 provides deep support for GPU-accelerated machine learning and offers improved developer tools that make it even easier to debug, optimize, and deploy Metal apps. On Mac, Metal 2 adds support for virtual reality (VR) rendering and external GPUs, and provides new APIs and optimizations to help developers adopt these new technologies within their apps.

Key Qualifications

  • Excellent programming skills and knowledge of C/C++
  • Development experience on Unix, Linux or macOS
  • Extraordinary software design, problem solving and debugging skills
  • Experience with GPU hardware and software architecture analysis, design, and implementation
