  • Implement Firmware Components: Design and implement low-level firmware components for CPU initialization, exception handling, MMU setup, coherency, and memory management.
  • CPU Design Collaboration: Collaborate with CPU design and silicon teams on pipeline features, caches, coherency protocols, branch prediction, and power states.
  • Linux Kernel Integration: Lead Linux kernel and RTOS integration for CPU subsystems, focusing on scheduling, memory, and power-aware optimizations.
  • Power Management Strategies: Drive CPU power management strategies: clock gating, DVFS, retention states, idle states, and adaptive scaling.
  • Performance Profiling: Perform CPU and memory subsystem performance profiling using simulators, emulators, JTAG, and hardware trace/debug tools.
  • Tuning and Optimization: Define system-level performance/power KPIs and lead tuning across CPU, firmware, kernel, and device drivers.
  • Mentorship and Architecture Reviews: Mentor engineers and guide architecture reviews, patents, and long-term CPU strategy.

Required Skills & Experience:

  • CPU Architecture: Deep expertise in ARMv8/v9 architecture, exception levels, MMU, caches, coherency protocols, ISA extensions, and PMU.
  • Firmware & Kernel: Strong hands-on experience in firmware, Linux kernel internals, RTOS, and device drivers.
  • Performance & Power: Proven ability in CPU pipeline analysis, memory subsystem tuning, DVFS, cpuidle/cpufreq frameworks, and power-performance tradeoff analysis.
  • Debugging & Bring-up: Experience in CPU bring-up, silicon validation, trace analyzers, emulators, JTAG, and kernel tracing tools.
  • Programming Skills: Proficiency in C/C++ and assembly (ARM), with Python/Shell for automation.
  • I/O & Interconnects: Familiarity with PCIe, Ethernet, I²C, SPI, CAN, USB, and memory buses (DDR, LPDDR).
  • Problem Solving: Strong ability to root-cause complex issues across CPU architecture, firmware, and OS layers.

Preferred Qualifications:

  • Open-source Contributions: Contributions to open-source CPU enablement (Linux kernel, toolchains, firmware frameworks).
  • Automotive or Edge Computing Background: Background in automotive, mobile SoCs, or Edge computing platforms with strict latency and performance KPIs.
  • Technical Leadership: Technical leadership in CPU/SoC co-design projects involving hardware, firmware, and OS integration.

Education:

  • Bachelor's or Master's degree: Bachelor's or Master's degree in Computer Engineering, Electrical/Electronics Engineering, or related field.
