Etched
Power Integrity Engineer
About this role
Etched is seeking a Power Integrity Engineer to design and validate power delivery networks for high-performance AI inference ASICs and systems. You'll own PDN methodology from architecture through production, ensuring robust power delivery across complex multi-rail designs using industry-standard EDA tools.
What you'll do
- Perform pre- and post-layout PDN analysis including target impedance profiling, decoupling capacitor optimization, and plane resonance mitigation
- Execute DC IR-drop and current density simulations to define PCB specifications for copper weight, via stitching, and layer allocation
- Conduct AC impedance analysis across the full power delivery chain from VRM output through package and die with ESR/ESL modeling
- Develop and validate VRM models, analyzing transient response, load-line behavior, and multiphase converter performance
- Support hardware bring-up and debug rail-level issues with root-cause analysis and corrective actions
- Collaborate with power design, layout, and ASIC teams to define power delivery architecture and establish design guidelines
What they're looking for
- Power integrity (PDN) analysis and target impedance methodology
- EDA tools: Ansys SIwave, Cadence Sigrity PowerDC/PowerSI, or Cadence Allegro
- DC IR-drop and AC impedance analysis across multiple frequency ranges
- VRM fundamentals: buck converters, multiphase design, transient response, and load-line control
- Multi-layer PCB stack-up design and power plane optimization
- High-current ASIC/CPU/GPU power delivery systems
- Python or MATLAB scripting for simulation automation
- Thermal-electrical co-simulation and thermal tradeoff analysis
Benefits
- Medical, dental, and vision coverage with $500/month credit for waiving medical
- Housing subsidy of $2,000 per month for those within walking distance of office
- Relocation support for those relocating to San Jose
- Wellness benefits including fitness and mental health programs
- Daily lunch and dinner provided at office
- Unlimited compute budget subject to ROI justification
