Role summary
NVIDIA is seeking a Senior High-Speed IO (HSIO) Validation Engineer to own the validation of HSIO subsystems (PCIe/NVLink) from start to finish. This role involves developing test plans, automation, resource planning, test execution, and bug resolution. The engineer will coordinate with various internal and external teams across different time zones to ensure product specification compliance and optimal performance. Responsibilities include assisting with hardware bring-up, solving system and board-level issues, reviewing schematics and PCB layouts, ensuring interoperability, and providing manufacturing support. The ideal candidate will have 6+ years of experience in HSIO validation, in-depth knowledge of HSIO protocols like PCIe, and experience with lab equipment and scripting languages like Python.
NVIDIA has continuously reinvented itself over two decades. Our invention of the GPU in 1999 sparked the growth of the PC gaming market, redefined modern computer graphics, and revolutionized parallel computing. More recently, GPU deep learning ignited modern AI — the next era of computing. NVIDIA is a “learning machine” that constantly evolves by adapting to new opportunities that are hard to solve, that only we can tackle, and that matter to the world. This is our life’s work, to amplify human imagination and intelligence. Make the choice to join us today.
We are now looking for a Senior High-Speed IO (HSIO) Validation Engineer!
What you will be doing:
Own HSIO (PCIe/NVLink) validation of products from start to finish including test plan development, automation, design for validation requirements, resource planning, coverage metrics, test execution, bug resolution, and release to production.
Coordinate with internal and external logic design, circuit design, board design, Simulation, diagnostics, firmware, driver, and marketing teams in different time zones, to ensure our products HSIO subsystem is specification compliant and tuned for optimal workload performance, and to drive the system into production.
Assist in the bring-up of new hardware and solving tough system and board level issues with a focus on HSIO at a system level.
Participate in reviewing board schematics, PCB layouts, and making design and component suggestions.
Ensure interoperability with connected devices and system components in sophisticated interconnect topologies.
Solve complex hardware and software HSIO issues at the system level on GPU accelerated computing platforms.
Provide engineering support for manufacturing in both NPI and MP stages of production.
What We Need to See:
Ability to work on site in hardware lab environment 5 days a week in HQ
BSEE or BSCE or equivalent experience
6+ years or more of experience in HSIO validation
In-depth understanding of the HSIO protocol (such as PCI Express, Infiniband, Ethernet), specification, and its operation at a system level.
Experienced in the operation of logic and protocol analyzer, and protocol exercisers.
