Principal Design Verification Engineer (SerDes/PHY)

Location: San Jose, California, United States

Salary: $207,000–$230,000 per year, depending on experience, level, and business need; discretionary bonus, incentives, and benefits may apply.

Company

hirify.global provides rack-scale AI infrastructure through semiconductor-based connectivity solutions and its COSMOS software suite, integrating technologies such as CXL, Ethernet, NVLink, PCIe, and UALink.

What you will do

• Architect UVM-based verification environments for SerDes/PHY IP, including PMA, PCS, and PHY-MAC interface layers.
• Define verification plans, coverage models, and sign-off criteria for high-speed serial link blocks.
• Develop SystemVerilog/UVM testbenches, sequences, scoreboards, and reference models for multi-Gbps SerDes lanes.
• Verify equalization, CDR, training, link bring-up, channel behavior, and PHY protocol compliance.
• Drive coverage closure, debug failures with designers, and manage regressions through tape-out.
• Mentor junior engineers and collaborate with analog/mixed-signal design, SoC integration, firmware, post-silicon validation, and customer engineering teams.

Requirements

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 8+ years of design verification experience with high-speed SerDes, PHY, or mixed-signal IP.
• Strong knowledge of equalization, including CTLE, DFE, and FFE, as well as CDR, training sequences, and link bring-up.
• Expert-level proficiency in SystemVerilog and UVM.
• Hands-on experience with analog/mixed-signal co-simulation and Real Number Modeling.
• Working knowledge of at least one high-speed serial protocol: PCIe, UALink, UCIe, Ethernet, or CXL.

Nice to have

• MS or PhD in Electrical Engineering or Computer Engineering.
• Experience with PCIe Gen 6/Gen 7, UALink, or UCIe SerDes/PHY IP verification.
• Familiarity with Palladium, Veloce, or ZeBu emulation platforms and gate-level simulation.
• Python or Perl scripting for verification automation and regression management.
• Experience with post-silicon bring-up and correlating pre-silicon coverage with silicon results.

Culture & Benefits

• Work on connectivity engines for advanced AI infrastructure and high-speed semiconductor products.
• Collaborate across analog, digital, SoC, firmware, validation, and customer engineering disciplines.
• Potential eligibility for discretionary bonuses, incentives, and benefits.
• Inclusive workplace that encourages applications from people with diverse backgrounds and experiences.
