The Metal API and Shader Instrumentation team is directly responsible for augmentation of system-level components to detect and diagnose Metal API and shading language issues and surface them to developers. The team collaborates closely with Metal production frameworks, GPU driver, compiler, ecosystem, tooling, and platform OS teams to deliver the best possible Metal developer experience. The successful candidate is a critical thinker with a passion for developing GPU APIs, capable of envisioning mechanisms to help game, graphics, and compute developers efficiently implement Metal applications. They can apply their software engineering skills to instrument complex applications and deliver undefined behavior and address sanitization across the graphics stack, from API surface down to shader code. They can also deliver validation and testing plans that provide strong confidence in the robustness and quality of the implementation.
