Job Overview

We are seeking an experienced CPU Architect to drive innovation in core CPU, firmware/OS enablement, and performance tuning for next-generation SoCs used in automotive and edge computing platforms.

The ideal candidate will work at the intersection of CPU design and system software, defining and architecting core CPU software interfaces, designing and implementing low-level firmware, and collaborating on CPU design and silicon teams.

Key Responsibilities:

  • Define Core CPU Software Interfaces: Align firmware, BSP, drivers with ARM CPU microarchitecture features.
  • Design Low-Level Firmware: Kernel components for CPU initialization, exception handling, MMU setup, coherency, and memory management.
  • Collaborate on CPU Design and Silicon Teams: Pipeline features, caches, coherency protocols, branch prediction, and power states.
  • Lead Linux Kernel Integration: 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: Simulators, emulators, JTAG, and hardware trace/debug tools.
  • Define System-Level Performance/Power KPIs: Lead tuning across CPU, firmware, kernel, and device drivers.
  • Mentor Engineers and Guide Architecture Reviews: Patents, long-term CPU strategy, and cross-functional team collaboration.

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, 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: Strict latency and performance KPIs.
  • Technical Leadership in CPU/SoC Co-design Projects: Hardware, firmware, and OS integration.

Education:

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