CPU Verification Fellow, RISC-V High-Performance Processor

Job Title

CPU Verification Fellow, RISC-V High-Performance Processor

Role Summary

Lead verification strategy and execution for next-generation RISC-V high-performance superscalar CPUs. Own verification planning and delivery across simulation, formal verification, emulation, FPGA prototyping, and silicon bring-up, and coordinate across architecture, RTL, firmware, compiler, SoC, and validation teams.

This is a hybrid role based in Santa Clara, CA or Austin, TX.

Experience Level

Senior-level (Fellow). The team seeks a senior technical leader with deep CPU verification experience; specific years of experience are not listed.

Responsibilities

Drive verification strategy, implement scalable methodology, and lead cross-functional execution from early design to tapeout and post-silicon validation.

• Define and own verification strategy for out-of-order, speculative, superscalar CPU cores and CPU subsystems.
• Build and scale verification plans, constrained-random environments, checkers, assertions, scoreboards, and coverage-driven tests.
• Lead development of CPU reference models, instruction generators, ISS-based checking, and differential testing frameworks.
• Direct use of formal verification, emulation, FPGA prototyping, and silicon bring-up to achieve verification closure.
• Drive bug triage, root-cause analysis, coverage closure, and tapeout readiness.
• Collaborate with architecture, RTL, firmware, compiler, SoC, and validation teams and mentor senior engineers to establish best practices.

Requirements

Concise list of required skills and desirable experience.

• Must-have: Deep experience verifying high-performance superscalar CPUs, ideally including out-of-order and speculative microarchitectures.
• Must-have: Strong RISC-V knowledge: ISA compliance, privileged architecture, virtual memory, atomics, vector extensions, and memory model behavior.
• Must-have: Proficiency in SystemVerilog, UVM, constrained-random verification, assertions, functional coverage, and advanced debug methodologies.
• Must-have: Hands-on experience with CPU reference models, instruction generators, ISS-based checking, differential testing, and large-scale CPU verification environments.
• Must-have: Practical experience with formal verification and integrating formal methods into CPU verification flows.
• Must-have: Proven ability to lead verification strategy, scale teams, and work cross-functionally.
• Nice-to-have: Experience with emulation, FPGA prototyping, silicon bring-up, tapeout readiness, performance modeling, compilers, or SoC-level verification.
• Requirement: Employment contingent on eligibility to access U.S. export-controlled technology; may require U.S. citizenship, permanent residency, or an applicable federal license.

Education Requirements

Not specified.
