About the role

Senior HSIO Validation Engineer to own end-to-end HSIO validation for NVIDIA products, bringing up hardware platforms from bring-up to production with cross-functional collaboration across multiple time zones.

Responsibilities

  • Own HSIO validation of NVIDIA products end-to-end, including test plan development, automation, design-for-validation requirements, resource planning, coverage metrics, test execution, bug resolution, and release to production.
  • Validate high-speed interfaces including PCIe, NVLink, C2C (Chip-to-Chip), Ethernet, USB, DP, HDMI, CXL etc. across the protocol, link, and physical layers.
  • Bring up new hardware platforms and debug sophisticated board- and system-level issues, working closely with logic/circuit design, board design, simulation, diagnostics, firmware, and software teams across multiple time zones.
  • Review board schematics, PCB layouts and BOM, provide development and component feedback, and ensure interoperability with connected devices in complex interconnect topologies.
  • Drive signal integrity characterization, link tuning, and margin analysis to ensure specification compliance, and efficient workload performance.
  • Define and drive HSIO functionality test coverage from link bring-up through stress and corner-case scenarios, including link training, error handling, power management, and interoperability across silicon and platform configurations.
  • Develop test automation to scale validation coverage and improve efficiency.
  • Provide engineering support to manufacturing during NPI and MP stage.

Qualifications

  • BS+ in EE/CE or equivalent experience.
  • 3+ years of post-silicon HSIO validation or system bring-up experience.
  • Ability to work on site in a hardware lab environment 5 days a week at NVIDIA HQ.
  • Solid understanding of at least one high-speed interface protocol — PCIe, NVLink, C2C, Ethernet, USB, CXL, Display and/or SerDes/signal integrity at the PHY level, including link training and system-level operation.
  • Hands-on experience with lab equipment such as high-bandwidth DSOs, BERTs, protocol/logic analyzers, protocol exercisers, and TDR.
  • Proven system-level debug skills on complex hardware platforms.
  • Strong verbal and written communication skills, with the ability to collaborate across teams and suppliers to deliver quality products on tight schedules.
