iOS GPU Compiler Driver Manager

Cupertino, CA
  • Job Code


Posted: Sep 10, 2019

Weekly Hours: 40

Role Number: 200097526

Apple's GPU Software team provides the graphics software foundation for all of Apple's innovative products, including iPhone, iPad, Apple TV, Mac, and Watch. Our responsibilities encompass the frameworks, developer tools, and hardware drivers for the GPU and Display devices for all of Apple's hardware

Metal provides near-direct access to the graphics processing unit (GPU), enabling you to maximize the graphics and compute potential of apps on iOS, macOS, and tvOS. Metal provides a low-overhead architecture with precompiled 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 enhanced developer tools that make it even easier to debug, optimize, and deploy Metal apps. On Mac, Metal 2 also adds support for virtual reality (VR) rendering and external GPUs, and provides new APIs and optimizations to help developers embrace these emerging technologies within their apps. And now Metal 3 provides enhanced support for GPU-driven pipelines, ray tracing, and pro applications. Metal 3 also significantly improves the developer experience with the Metal Memory Debugger and Simulator support

We are looking for an engineering manager to lead the team responsible for building compiler drivers for iOS devices, and collaborating with the other driver and hardware groups to bring Metal to life. The ideal candidate would have previous GPU driver or GPU compiler experience and be willing to learn about the other, as well as previous management experience
