Staff Design Verification Engineer – High Performance CPU Core

SiFive is looking for a Staff Design Verification Engineer to drive verification of high-performance CPU core units. This role spans key core areas such as Frontend, Midcore, Load-Store Unit, and Hardware Prefetch, and is aimed at engineers who can go beyond executing assigned tests to define strategy, identify verification gaps early, solve difficult microarchitectural problems, and raise the quality bar for the broader team.

What You Will Do

Own verification planning and execution for one or more high-performance out-of-order CPU core areas, drive block-level and core-level verification planning, debug, coverage analysis, and closure for complex CPU features and microarchitectural behavior, define verification strategies for challenging behaviors such as instruction fetch, branch prediction, issue and dispatch behavior, pipeline interactions, load/store ordering, hazard handling, memory consistency, and hardware prefetch correctness.

Why It Might Be a Fit

You will work closely with architecture, RTL, performance, and verification teams to ensure design intent is captured correctly, risks are identified early, and signoff quality is achieved with strong technical judgment and scalable methodology.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
• 7+ years of relevant experience in ASIC, CPU/core, or SoC design verification.
• Strong hands-on experience with SystemVerilog and UVM-based verification.
• Direct experience with CPU/core verification and strong understanding of computer architecture and CPU microarchitecture.
• Experience in one or more high-performance CPU areas such as Frontend, Midcore, Load-Store Unit, memory ordering/consistency, or hardware prefetch verification.
• Strong knowledge of verification flow methodology, including test planning, constrained-random or directed stimulus generation, failure analysis, coverage analysis, and coverage closure.
• Strong debug skills and the ability to translate architectural intent into effective verification strategy and execution.

Benefits

• Base pay
• Variable/incentive compensation
• Equity
• Comprehensive, competitive benefits package
• Healthcare and retirement plans
• Paid time off
