Software and Services


Weekly Hours: 40
Role Number:200224125
The GPU compiler team is seeking a strongly motivated engineer to work on high performance GPU compilers. Our team supports many different GPU architectures, devices (including iPhone, iPad, Apple Watch, Apple TV), and billions of customers. We work with many different organizations within Apple – architecture, silicon engineering, drivers, frameworks, tools and Xcode. This kind of collaboration and cross functional reach allows our team to influence architecture and helps us deliver phenomenal performance, functionality and robustness for all shaders and kernels that run on Apple GPU. Our team is focused on improving our user’s experience by maximizing the execution speed of the code generated for Apple’s mobile GPUs, while minimizing energy consumption. We are enabling new GPU architectures, technologies, and applications through innovation in compilers. You will have experience with some of the skills below. Nobody is expected to have experience with all of these, but we are looking for someone with a strong desire to learn what you don’t know.

Key Qualifications

  • Experience with assembly programming, system-level programming or writing OS drivers.
