About the role

  • Headquartered in Silicon Valley, we operate across a mix of remote and on‑site locations in the U.S. and Canada.
  • This role ensures signal fidelity, robust power delivery, and strong correlation between simulation and hardware for next‑generation AI compute systems.
  • Our salary ranges are determined by role, level, experience, and location.

Responsibilities

  • Perform pre‑ and post‑layout SI simulations (eye diagrams, crosstalk, insertion/return loss) for UCIe, D2D, SerDes, and Ethernet links.
  • Build and validate S‑parameter, IBIS‑AMI, and behavioral models for packages, PCBs, sockets and cables.
  • Collaborate with IC design, packaging, and board teams to define electrical requirements and debug issues.
  • Knowledge of PCB materials, stack‑ups, and constraint‑driven design.

Requirements

  • Required Skills & Qualifications
  • Experience with UCIe, D2D, SerDes, or Ethernet interfaces.
  • Hands‑on experience with VNA, TDR, oscilloscopes.

Nice to have

  • Model PDNs for low‑voltage, high‑current rails
  • run AC/DC, impedance, and IR‑drop simulations
  • come up with decoupling cap selection.
  • Guide PCB/package layout teams on stack‑ups, routing constraints, return‑path continuity, and decoupling strategy.
  • Conduct bring‑up, VNA/TDR measurements, oscilloscope validation, and correlate hardware results with simulations.
  • Evaluate new SI/PI methodologies, materials, and tools for next‑generation architectures.
  • Evaluate emerging interconnect technologies such as CPC, CPO, and establish electrical-optical-electrical end-to-end simulation and validation methodologies.
  • B.S./M.S. in Electrical Engineering or related field.

Compensation

  • Target base salary for this role is $180,000-$240,000 per year + meaningful equity + benefits + 401k. Our salary ranges are determined by role, level, experience, and location.
