Senior Power and Performance Validation Engineer - Austin, Texas, United States
Originally posted 22 June 2026 by the employer. Relisted by the employer on 8 October 2026.
About the role
This role drives power, thermal, and performance validation strategy and execution across pre-silicon and post-silicon environments for AI compute silicon and platforms. You will lead characterization activities across CPU, memory, interconnect, and high-speed I/O subsystems.
What you'll do
- Define validation strategies and comprehensive plans covering functional, stress, workload, and corner-case scenarios for AI compute silicon and platforms. - Lead post-silicon bring-up and characterization activities for power and performance validation. - Drive validation of CPU, memory, interconnect, and high-speed I/O subsystems under complex workload conditions. - Develop scalable automation frameworks, regression infrastructure, and reporting tools using Python. - Design and execute benchmark workloads, parameter sweeps, and performance experiments to identify optimization opportunities and bottlenecks. - Collaborate with architecture, RTL, firmware, software, and systems teams to debug and resolve complex technical issues.
What you'll need
- Strong experience in power and performance validation, silicon characterization, or system performance engineering. - Deep understanding of modern SoC architecture, including CPU, memory, interconnect, and high-speed I/O technologies. - Strong Linux systems knowledge and low-level performance analysis experience. - Strong Python programming skills for automation, orchestration, and data analysis. - Experience with benchmarking and profiling tools such as stress-ng, fio, perf, iperf, or equivalent technologies. - Experience debugging complex hardware and software interactions.
