Senior High-Speed IO Validation Engineer
$136,000 - $258,750 USD yearly
About the role
This role involves end-to-end validation of High-Speed IO (HSIO) for NVIDIA products, driving system-level debug from bring-up to full-scale production. This position focuses on validating PCIe, NVLink, C2C, Ethernet, USB, DP, HDMI, and CXL interfaces across protocol, link, and physical layers.
What you'll do
- Own HSIO validation, including test plan development, automation, and bug resolution.
- Validate high-speed interfaces like PCIe, NVLink, C2C, Ethernet, USB, DP, HDMI, CXL across protocol, link, and physical layers.
- Bring up new hardware platforms and debug complex board- and system-level issues.
- Review board schematics, PCB layouts, and BOM, providing development and component feedback.
- Drive signal integrity characterization, link tuning, and margin analysis.
- Define HSIO functionality test coverage from link bring-up through stress and corner-case scenarios.
What you'll need
- 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.
- Solid understanding of at least one high-speed interface protocol: PCIe, NVLink, C2C, Ethernet, USB, CXL, Display, or SerDes/signal integrity at the PHY level.
- 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.
