Job Title: CPU Firmware Architect\

Role Overview:

\

We are seeking a highly skilled Core CPU Architect with 12–15 years of experience in ARM-based CPU architecture, embedded firmware, and low-level system software.

\

This role requires a hands-on technical leader with deep expertise in CPU microarchitecture, cache/memory subsystems, power-performance optimization, and Linux kernel integration.

\

The ideal candidate will work at the intersection of CPU design and system software, driving innovations in core CPU, firmware/OS enablement, and performance tuning for next-generation SoCs used in automotive and edge computing platforms.

\Key Responsibilities:\
  • \
  • Define and architect core CPU software interfaces (firmware, BSP, drivers) aligned with ARM CPU microarchitecture features.\
  • Design and implement low-level firmware and kernel components for CPU initialization, exception handling, MMU setup, coherency, and memory management.\
  • Collaborate with CPU design and silicon teams on pipeline features, caches, coherency protocols, branch prediction, and power states.\
  • Lead Linux kernel and RTOS integration for CPU subsystems, focusing on scheduling, memory, and power-aware optimizations.\
  • Drive CPU power management strategies: clock gating, DVFS, retention states, idle states, and adaptive scaling.\
  • Perform CPU and memory subsystem performance profiling using simulators, emulators, JTAG, and hardware trace/debug tools.\
  • Define system-level performance/power KPIs and lead tuning across CPU, firmware, kernel, and device drivers.\
  • Mentor engineers and guide architecture reviews, patents, and long-term CPU strategy.\
  • Partner with cross-functional teams to deliver high-performance CPU platforms.\
    • \Required Skills & Qualifications:\
      • \
      • 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.\
      • Debug & Bring-up: Experience in CPU bring-up, silicon validation, trace analyzers, emulators, JTAG, and kernel tracing tools.\
      • Programming: 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:\
          • \
          • Contributions to open-source CPU enablement (Linux kernel, toolchains, firmware frameworks).\
          • Background in automotive, mobile SoCs, or Edge computing platforms with strict latency and performance KPIs.\
          • Technical leadership in CPU/SoC co-design projects involving hardware, firmware, and OS integration.\
            • \Education:\
              • \
              • Bachelor's or Master's degree in Computer Engineering, Electrical/Electronics Engineering, or related field.\
                • ],
