About The Position

Imagine what you can do here. Apple is a place where extraordinary people gather to do their lives best work. Together we create products and experiences people once couldn’t have imagined, and now, can’t imagine living without. It’s the diversity of those people and their ideas that inspires the innovation that runs through everything we do. Design and develop software for graphics processing unit (GPU) drivers for Apple silicon GPUs. Ensure high performance work scheduling occurs on the GPU across Apple products. Schedule low latency commands on GPU designs. Implement and evaluate workload scheduling and quality of service policies for the GPU performance analysis and optimization of the driver and firmware for optimum scheduling performance. Validate GPU and firmware features for new System-on-Chips (SoCs) post-silicon bring-up. Design and evaluate possible future GPU and firmware architectures. Create and maintain the kernel mode driver and firmware running on GPUs for Apple's embedded devices including iPhones, iPads, iPods, and AppleTV. Integrate GPU drivers into iOS/macOS software. Provide data for performance and debugging tools and complete performance analysis and tuning of software/hardware. Perform specification reviews and contribute to new ideas for next generation GPU and iOS/macOS.
