Performance Control Architect - Platform Architecture

Platform Architecture is looking for a Performance Control Software Engineer to measure, analyze and control the relationship between power and performance in Apple’s most advanced systems. In this position, you will study the execution of workloads on Apple silicon across all Apple platforms and leverage that understanding to invent new operating system performance control features. You will design and conduct performance experiments, create instrumentation and data visualizations, prototype innovative in-kernel performance control algorithms, collaborate with teams ranging from the core operating system through user-facing applications, and productize the software that controls the performance of every workload executed on hundreds of millions of Apple products around the world. Design and conduct experiments to characterize execution efficiency and the effects of physical constraints such as temperature or current limits. Use excellent empirical methodology to illuminate power–performance tradeoffs. Collaborate with and influence a broad cross-functional audience spanning processor architecture, silicon engineering, system integration, OS development and application software performance evaluation. Identify opportunities to improve the measurement and control capabilities of Apple SoCs. Invent new performance control concepts and carry them through prototyping, production implementation and tuning. BS in Computer Science, Electrical and Computer Engineering or similar engineering degree. Experience with operating system design and implementation. System level or low level software development experience in C or C++. Minimum of 20 years relevant industry experience. MS in Computer Science or Electrical and Computer Engineering or similar engineering degree. Knowledge of computer architecture and hardware performance monitoring instrumentation. Userland software development experience in environments such as C, C++, Swift or Python.
