Apple AR/VR Job | Performance Engineer

Job(岗位): Performance Engineer

Citys(岗位城市): Santa Clara Valley (Cupertino), California, United States

Date(发布日期): 2021-12-22


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

This team recently 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.
