Power Integrity Engineer

The role

You will own the power integrity methodology for high-power PCB and system designs. This includes ensuring robust power delivery to high-performance ASICs and supporting components from early architecture through final release.

What you will do

• Perform pre- and post-layout PDN analysis for high-current ASIC power rails
• Execute DC IR-drop and current density simulations
• Conduct AC impedance analysis from VRM output through package and die
• Develop and validate VRM models
• Perform power-plane thermal co-simulation
• Drive design rule checks for PI compliance
• Collaborate with power design, PCB layout, and ASIC/package teams
• Support bring-up and debug rail-level issues
• Develop and maintain simulation-to-hardware correlation databases

Required qualifications

• B.S. or M.S. in Electrical Engineering or a closely related discipline
• 5+ years of hands-on PI experience on high-current, high-performance designs
• Proficiency with industry PI EDA tools (Ansys SIwave, Cadence Sigrity PowerDC/PowerSI/OptimizePI, or equivalent)
• Strong understanding of target impedance methodology, decoupling network design, plane resonances, and anti-resonance mitigation
• Experience with DC IR-drop analysis, current density limits, and via/plane current-carrying capacity
• Working knowledge of VRM fundamentals: buck converter operation, multiphase design, transient response, and load-line/AVP concepts
• Working knowledge of multi-layer PCB stack-up design and power plane allocation strategies

Nice to have

• Prior work in data center, AI/ML accelerator, networking, or high-performance computing (HPC) hardware environments
• Experience with vertical power delivery, high-current lateral delivery tradeoffs, or 48V-to-point-of-load architectures
• Package-level PDN co-analysis and experience working with die/package power models from ASIC teams
• Experience scripting automated PI simulation flows using Python or MATLAB

Benefits

• Medical, dental, and vision packages with generous premium coverage
• $500 per month credit for waiving medical benefits
• Housing subsidy of $2,500 per month for those living within walking distance of the office
• Relocation support for those moving to San Jose (Santana Row)
• Various wellness benefits covering fitness, mental health, and more
• Daily lunch and dinner in our office
• Unlimited compute budget subject to ROI justification
