Engineer / Staff / Sr. Staff Engineer - CPU Verification (RAS)
SiFiveJob Title
Engineer / Staff / Sr. Staff Engineer - CPU Verification (RAS)
Role Summary
Join the CPU verification team to develop and maintain block- and subsystem-level verification environments for SiFive's CPU IP with emphasis on Reliability, Availability, and Serviceability (RAS). The role spans multiple seniority levels; specific responsibilities and ownership depend on experience.
Experience Level
Multiple levels (Engineer through Sr. Staff). Typical candidates have 1+ years of verification experience; exact leveling will be matched to demonstrated skills and technical ownership.
Responsibilities
Primary responsibilities include building verification environments, deriving requirements from architecture, writing tests, debugging RTL/simulation issues, and maintaining regression infrastructure.
- Develop and maintain block- and subsystem-level testbenches using SystemVerilog and UVM.
- Extract verification requirements from architecture specifications and contribute to test plan reviews.
- Write directed and constrained-random tests to achieve functional and code coverage targets.
- Debug simulation failures and collaborate with RTL designers to resolve complex issues.
- Maintain and optimize automated regression setups and CI workflows.
Requirements
Must-have skills; hiring level determines depth of ownership.
- Strong understanding of advanced computer architecture (pipelines, memory hierarchies, caches).
- Proficiency in SystemVerilog and UVM for functional verification.
- Solid knowledge of verification methodologies including constrained-random stimulus and coverage-driven verification.
- Experience debugging simulations and working closely with RTL designers.
- Scripting skills for automation (Python, Perl, or Bash).
- Experience with automated regression frameworks and CI.
Preferred:
- Experience with RAS verification techniques: ECC testing, parity checks, data poisoning, hardware fault injection.
- Familiarity with the RISC-V ISA and custom extensions.
- Experience operating under export-control and work-authorization constraints.
Education Requirements
Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related technical field as stated in the posting. The role references 1+ years of verification experience in conjunction with these degrees.
