About The Role

As a Principal Design Verification Engineer, you will own the verification strategy and execution for complex IPs or full-chip SoC. You will lead a team of verification engineers, define methodologies, drive coverage closure, and ensure high-quality silicon delivery.

What You'll Do

Leadership & Strategy

• Define and drive end-to-end verification strategy (block → subsystem → full-chip)
• Build, mentor, and scale a high-performing DV team
• Establish verification plans, milestones, and coverage goals
• Drive alignment across architecture, RTL, and physical design teams
  
  

Verification Execution

• Lead development of UVM-based verification environments
• Define testbench architecture, stimulus strategy, and reusable components
• Drive functional, code, and assertion coverage closure
• Oversee regression infrastructure, debug, and signoff criteria
  
  

Advanced Verification & Signoff

• Drive GLS (Gate-Level Simulation) with SDF annotation and timing-aware debug
• Manage low-power verification (UPF/CPF) and power-aware simulation
• Oversee formal verification, linting, CDC/RDC analysis
• Ensure robust reset, clocking, and cross-domain verification
  
  

Cross-Functional Collaboration

• Work with RTL teams on design-for-verification (DFV) improvements
• Collaborate with PD teams on timing-related verification issues
• Support post-silicon bring-up and debug
• Interface with customers/partners on verification readiness and quality
  
  

Required Qualifications

• Bachelor’s/Master’s degree in Electrical Engineering or related field
• 12–15 years of experience in ASIC/SoC design verification
• Proven experience leading verification teams and delivering multiple tapeouts
• Strong expertise in:
• SystemVerilog and UVM methodology
• Functional coverage, assertions (SVA), and constrained-random verification
• Debugging complex SoC-level issues
• Hands-on experience with industry-standard tools such as:
• Synopsys VCS / Cadence Xcelium
• Synopsys Verdi
• Strong understanding of:
• Clock/reset domain crossings (CDC/RDC)
• Low-power verification methodologies
• Gate-level simulation and SDF annotation
• Excellent leadership, communication, and problem-solving skills
  

Preferred Qualifications

• Experience in CPU/GPU/AI/Networking SoCs
• Expertise in GLS debug (X-propagation, SDF issues, timing failures)
• Familiarity with emulation platforms (e.g., Synopsys ZeBu)
• Experience with post-silicon validation and bring-up
• Knowledge of performance verification and system-level validation
• Strong scripting skills (Python/TCL) for automation and regression scaling
  
  

Compensation Range: $250,000–$280,000 per year (California). This range represents the anticipated base pay for this role based in California; the final offer may vary based on qualifications, experience, and location.

Benefits

• Medical, Dental, & Vision - 100% covered premiums
• Equity - Stock Options
• 401(k) match
• WFH Hardware
