TL;DR · High-speed Electrical/Optical Post-Silicon Engineer

The Senior Lead High-speed Electrical/Optical Post-Silicon Engineer joins the Central Hardware Systems team to drive measurements, validation, and debug for next-generation 224G/448G electrical and optical interconnects. This role involves performing channel characterization across packages, PCBs, and cables while correlating bench data with simulations. The engineer will lead post-silicon bring-up, perform SerDes validation, and conduct PDN failure isolation involving rail noise and power delivery issues. Key responsibilities include developing automation scripts, data reduction tools, and stress content to identify electrical or optical failures. Required expertise includes high-speed digital design, SI/PI fundamentals, and proficiency with VNAs, oscilloscopes, BERTs, and TDR equipment. The role addresses complex technical challenges in link training, equalization, and signal integrity for standards like PCIe, CXL, and Ethernet while ensuring system readiness across various hardware platforms and software environments.

What you'll do

  • Perform high-speed electrical and optical measurements for 224G/448G interconnects across packages, PCBs, and cables.
  • Correlate bench measurement data with simulations to analyze S-parameters, jitter, noise, and link robustness.
  • Lead post-silicon bring-up, characterization, and system validation for SerDes, optical modules, and retimers.
  • Conduct PDN measurements to identify and isolate failures related to rail droop, ripple, and power delivery.
  • Develop automation scripts, data reduction tools, and regression flows to isolate electrical and optical failures.
  • Translate complex lab signatures into root cause analysis hypotheses and actionable debug plans.
  • Produce technical reports regarding measurement findings, risk assessments, and recommended actions for stakeholders.

What we're looking for

  • Bachelor's degree with 8+ years of experience, Master's with 7+ years, or PhD with 6+ years in a related engineering field.
  • 8+ years of relevant experience in post-silicon, SI/PI, SerDes/DDR, optical, package/PCB, or system validation.
  • Strong fundamentals in high-speed digital design, SerDes/DDR PHYs, transmission lines, and measurement correlation.
  • Hands-on experience with VNAs, oscilloscopes, BERTs, TDR/TDT, spectrum analyzers, and precision probing tools.
  • Experience validating and debugging high-speed links such as DDR, PCIe/CXL, Ethernet, or UCIe.
  • Strong PDN and system debug experience including rail noise, droop, and workload-driven power stress.
  • 4+ years of experience with programming languages like C, C++, Java, or Python.
  • 4+ years of experience with debugging techniques.
