  • 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:
