Job Level
SeniorLead
About the role
- Silicon bringup, validation, and debug NVIDIA’s multiple HSIOs, including NVLink and NVLink-C2C
- Own the post-silicon electrical validation of Chip-to-Chip (C2C) and NVLink high-speed interfaces across multiple product lines (GPU, CPU, DPU, SoC)
- Develop validation plans, test methodologies, and automation frameworks for link bring-up, margining, and compliance
- Execute validation of signal integrity (SI), power integrity (PI), timing margins, equalization tuning, and error metrics across PCIe Gen5/Gen6, C2C, and NVLink interconnects
- Debug link-level and system-level electrical issues including jitter, crosstalk, transient noise, BER, and channel loss problems
- Collaborate closely with design, architecture, system, and SI/PI teams to ensure robust interface design and production-level performance
- Characterize link health under PVT (process, voltage, temperature) corners and stress conditions to ensure product reliability
- Deliver data analysis, reports, and recommendations to influence design decisions and drive issue resolution
- Investigate HSIO power features, datapath analysis, and electrical for the next generation of products
- Power feature characterization and tuning for key use cases, balancing performance and power
Requirements
- BS or MS degree in EE/CE or equivalent experience
- 8+ years working on bringup, validation, or design of HSIOs (eg: PCIE/CXL, DDR, USB, UCIE)
- Experience with HSIOs like PCIE or chip-to-chip interconnects including understanding of process/temp/voltage sensitivity
- Understanding of HSIO power management
- Understanding of firmware/driver structures and their interaction with Hardware
- Strong EE fundamentals; knowledgeable in computer architecture, high speed interfaces, timing analysis, process variations, statistical error rates and power analysis
- Enjoy working in a collaborative environment
