Senior High-Speed IO Validation Engineer

We are now looking for a Senior High-Speed IO (HSIO) Validation Engineer to join our hardware product team! This is an outstanding opportunity to work with next-generation GPU, CPU and high-performance computing platforms, driving system-level debug from bring-up all the way to full-scale production. Join a team that pushes technical boundaries, fosters close collaboration, and holds a high bar for quality!

What you'll be doing

• 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.

What we need to see:

• 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.

Ways to stand out from the crowd:

• Proven experience debugging PCIe physical and link layer behavior, including link training, equalization, and lane margining; solid understanding of the data link and transaction layers.

• Experience with NVLink, C2C, or other proprietary chip-to-chip interconnects.

• Strong signal integrity background — SerDes equalization, eye/margin analysis, jitter decomposition, and channel modeling.

• Experience with Ethernet (multi-Gbps to 400G+/800G) or Display Port/HDMI validation.

• Experience with CXL — the CXL.io/.cache/.mem protocols and memory-coherency validation over the shared PCIe Gen5/6 PHY
