CPU Architect Job Opportunity

We are seeking a skilled Core CPU Architect to join our team. As a highly experienced professional, you will have extensive knowledge in ARM-based CPU architecture, embedded firmware, and low-level system software.

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.
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.
  • 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, IC, SPI, CAN, USB, and memory buses (DDR, LPDDR).
  • Problem Solving: Strong ability to root-cause complex issues across CPU architecture, firmware, and OS layers.

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

This role requires a strong technical leader who can collaborate with cross-functional teams to drive innovative solutions.
