This role ensures signal fidelity, robust power delivery, and strong correlation between simulation and hardware for next‑generation AI compute systems.
Key Responsibilities
- Perform pre‑ and post‑layout SI simulations (eye diagrams, crosstalk, insertion/return loss) for UCIe, D2D, SerDes, and Ethernet links.
- Model PDNs for low‑voltage, high‑current rails; run AC/DC, impedance, and IR‑drop simulations; come up with decoupling cap selection.
- Build and validate S‑parameter, IBIS‑AMI, and behavioral models for packages, PCBs, sockets and cables.
- 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.
- Collaborate with IC design, packaging, and board teams to define electrical requirements and debug issues.
- 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.
- Deep understanding of EM theory, transmission lines, and high‑speed signaling.
- Expertise with SI/PI tools (Keysight ADS, Ansys HFSS, Cadence Sigrity/PowerSI).
- Experience with UCIe, D2D, SerDes, or Ethernet interfaces.
- Knowledge of PCB materials, stack‑ups, and constraint‑driven design.
- Hands‑on experience with VNA, TDR, oscilloscopes.
- Python/Matlab scripting for automation is a plus.
