Job Description

Summary

As a member of the Apple Silicon GPU Compiler Backend Performance Team, you’ll implement improvements to the open-source LLVM mid-level optimizer as well as our LLVM-based machine-dependent code generator for the Apple GPU architecture.

Description

The Apple GPU architecture is part of the silicon that powers macOS, iOS, iPadOS, tvOS, and watchOS devices. The work we do has direct impact on the billions of Apple devices shipped to date. We work with many different organizations within Apple – hardware architecture, silicon engineering, device drivers, application frameworks, and the Xcode developer tools. This kind of collaboration and cross-functional reach allows our team to influence the hardware architecture and software stack.

We're part of delivering phenomenal performance, functionality, and robustness for all graphics shaders and compute kernels that run on Apple GPUs.

Our team is focused on improving the end-user experience by maximizing the execution speed of the code generated for Apple GPUs while minimizing energy consumption. We are enabling new GPU architectures, technologies, and applications through innovation in compilers.
