System Performance Engineer, Consumer Devices

Responsibilities

• Develop system performance benchmarks, methodologies, and policies to evaluate end-to-end product behavior.
• Profile and analyze performance across key product use cases and workloads using custom and industry-standard profiling tools.
• Partner closely with engineering teams to identify bottlenecks and drive performance optimizations across the software stack.
• Define high-level product KPIs and establish measurement frameworks to measure launch readiness and monitor performance throughout the product lifecycle.
• Measure, report, and track metrics including system responsiveness, memory utilization, cold boot performance, long-term stability, and behavior under constrained conditions such as thermal limits and low battery states.
• Investigate field performance regressions and drive issues to resolution using data-driven analysis.

Requirements

• Deep experience shipping embedded or high-performance systems on Linux, Android, or iOS devices.
• Strong proficiency in C/C++, Python, or Rust, with exceptional operating systems fundamentals, including process management, IPC, drivers, interrupts, power management, media frameworks, graphics, filesystems, and networking.
• A proven track record shipping real-time systems operating under tight latency, power, and memory constraints.
• Expertise with profiling and debugging tools such as Perfetto, GDB, LLDB, perf, ftrace, or Instruments.
• Experience building instrumentation, analytics, and performance tuning frameworks.

Nice-to-Haves

• Familiarity with statistics, experimentation methodologies, or data science concepts.
• Experience collaborating cross-functionally with embedded software, systems, camera and vision, audio, graphics, applications, and hardware teams.
• Experience defining product KPIs, benchmarking methodologies, and launch readiness metrics for hardware products.
• Experience investigating field performance regressions and driving fixes through cross-functional collaboration.
