About the position
Do you love creating elegant solutions to highly complex challenges? Do you intrinsically see the importance in every detail? As part of our Silicon Technologies group, you'll help design and manufacture our next-generation, high-performance, power-efficient processor, system-on-chip (SoC). You'll ensure Apple products and services can seamlessly and efficiently handle the tasks that make them beloved by millions. Joining this group means you'll be responsible for crafting and building the technology that fuels Apple's devices. Together, you and your team will enable our customers to do all the things they love with their devices! Join a team of expert software engineers with diverse backgrounds (graphics, video encoding, video processing, file systems, CPUs and caching, kernel programming, embedded systems) to develop graphics validation software and integrate it into system level test environment.
Responsibilities
- Write shaders that stress the GPU and cause high bandwidth traffic to and from the memory subsystem.
- Apply deep understanding of GPU architecture to write tests that stress the pipeline and exercise the interaction between the GPU and different IP blocks on the SoC.
- Use necessary driver and firmware APIs to compile shaders and prime operations to move data around in the SoC using the GPU threads/SIMD groups.
- Understand different levels of GPU memory hierarchy (Shared, Global, etc.).
- Debug SoC software and hardware issues, and perform system level validation.
Requirements
- Experienced with Graphics, OpenGL, and CUDA.
- Understanding of the GPU pipeline and graphics theory.
- Understanding of system and SoC architectures.
- Experienced with image processing, memory hierarchies, and compilers.
- Strong C/C++ programming skills.
- Proficient in Python and GNU Make.
- Deep understanding of compute systems, operating systems, and computer architecture.
- Passionate about writing code close to the hardware, and debugging.
- In-depth knowledge and experience in SoC system level validation and debugging of SoC software and hardware issues.
Nice-to-haves
- Enjoy the validation mentality: meticulous, curious, and persistent.
