About the role

Lead SI/PI Engineer responsible for solving complex high-speed SI/PI challenges across silicon, package, PCB, flex, and advanced packaging in next-generation AI compute systems. Hands-on technical role with deep analysis, cross-team collaboration, and system-level validation.

Responsibilities

  • Solve complex signal integrity and power integrity problems for high-speed AI compute platforms, including chip-to-chip and chip-to-board interfaces.
  • Perform advanced pre-layout and post-layout SI/PI analysis across PCBs, flex circuits, rigid-flex assemblies, connectors, and advanced packages.
  • Lead root-cause analysis of challenging SI/PI issues such as margin shortfalls, impedance discontinuities, coupling, resonances, and simulation-to-hardware mismatches.
  • Analyze and resolve SI/PI challenges associated with flex circuits, high-speed flex connectors, interposers, and advanced packaging technologies.
  • Analyze and troubleshoot power delivery networks using DC and AC simulations and hardware correlation to resolve performance and stability issues.
  • Define and refine PCB, rigid-flex, and flex circuit stack-ups, material selections, and impedance structures as required to meet performance targets.
  • Review schematics, PCB layouts, and flex designs to identify SI/PI risks and recommend targeted design changes.
  • Work closely with silicon and package design teams to resolve SI/PI issues related to bump/ball assignments, package-to-PCB transitions, and interface interactions.
  • Act as a technical escalation point for complex SI/PI issues across multiple programs.

Qualifications

  • Master’s degree in Electrical Engineering.
  • 15+ years of demonstrated depth of expertise in system-level signal integrity and power integrity engineering for high-speed hardware systems.
