Responsibilities

• Participate in the design, prototyping, implementation and code review of kernel features related to performance control, power management and scheduling.
• Design and conduct experiments to characterize execution efficiency and the effects of physical constraints such as temperature or power delivery.
• Use excellent empirical methodology to illuminate power–performance tradeoffs.
• Influence a broad cross-functional audience spanning processor architecture, silicon engineering, system integration, OS development and application software performance evaluation.
• Find opportunities to improve the measurement and control capabilities of Apple silicon.

Minimum Qualifications

• BS in Computer Science, Electrical and Computer Engineering or similar engineering degree.
• Experience with operating system design and implementation.
• Kernel software development experience in C or C++.

Preferred Qualifications

• Minimum of 10 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.
• Experience with system-level performance profiling, debugging tools, and tracing frameworks (e.g., DTrace, Instruments, perf).
• Familiarity with data analysis, statistical modeling, or visualization techniques to interpret complex power and performance metrics.
