Job Title:

CPU Architecture Specialist

Role Overview

We are seeking a highly skilled and experienced CPU architect to join our team. As a key member of our architecture team, you will be responsible for designing and developing cutting-edge CPU architectures that meet the needs of our clients.

This role requires a deep understanding of CPU microarchitecture, cache/memory subsystems, power-performance optimization, and Linux kernel integration. You will work closely with our design and silicon teams to develop innovative solutions that drive business growth and customer satisfaction.

In this role, you will have the opportunity to make a significant impact on the development of our next-generation SoCs used in automotive and edge computing platforms.

Key Responsibilities
  1. CPU Software Interface Design: Define and architect core CPU software interfaces (firmware, BSP, drivers) aligned with ARM CPU microarchitecture features.
  2. Firmware and Kernel Development: Design and implement low-level firmware and kernel components for CPU initialization, exception handling, MMU setup, coherency, and memory management.
  3. Collaboration and Leadership: 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.
  4. Performance Tuning: 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.
  5. Team Management: 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 & 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 Projects: 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
  • Degree: Bachelor's or Master's degree in Computer Engineering, Electrical/Electronics Engineering, or related field.
