Engineer, CPU Performance Verification
$100,000 - $500,000 USD yearly
Focus on performance verification and RTL-to-model correlation for a CPU based on the RISC-V ISA.
Originally posted 8 November 2026 by the employer.
About the role
You will drive performance verification and correlation between RTL and the performance model within the CPU design team. The position focuses on a CPU based on the RISC-V ISA, collaborating directly with core architects and RTL engineers.
What you'll do
- Verify performance and correlate RTL against the performance model to drive improvements in CPU microarchitecture.
- Collaborate closely with RTL engineers and core architects to meet performance goals, debug miscorrelation, and verify performance features.
- Draft performance testplans and develop targeted microbenchmarks to exercise performance features and expose bottlenecks.
- Enhance tools and methodologies for performance analysis and correlation to improve development efficiency.
- Optimize power, performance, and area while driving performance experiments and evaluating results.
What you'll need
- Experience analyzing modern CPU performance data, identifying bottlenecks, and building analysis tools.
- Proficiency in C++ and Python, with an understanding of industry-standard tools for compilation, simulation, and emulation.
- Knowledge of the architecture and microarchitecture of high-performance CPU cores.
- Experience debugging RTL and logic across multiple design hierarchies and pre-silicon environments.
- Exposure to performance modeling and RTL-to-model correlation.
Skills: RISC-V, CPU microarchitecture, RTL, performance modeling, C++, Python
