Job Overview

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

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.

This role is responsible for defining and architecting core CPU software interfaces (firmware, BSP, drivers) aligned with ARM CPU microarchitecture features.

  • CPU Software Interfaces:
  • Firmware and Kernel Components: Design and implement low-level firmware and kernel components for CPU initialization, exception handling, MMU setup, coherency, and memory management.
  • 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 integration for CPU subsystems, focusing on scheduling, memory, and power-aware optimizations.
  • CPU Power Management: 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: Mentor engineers and guide architecture reviews, patents, and long-term CPU strategy.
  • Cross-Functional Collaboration: Partner with cross-functional teams to deliver high-performance CPU platforms.
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: Contributions to open-source CPU enablement (Linux kernel, toolchains, firmware frameworks).
  • Background in Automotive or Edge Computing: 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.
