Senior Digital Design Engineer - High-Speed I/O and Photonics

About the role

The mixed-signal high-speed I/O group at NVIDIA delivers innovative PHY designs that power the most powerful AI systems in the world. Our portfolio includes PHY IPs and Chips for both copper and fiber channels, supporting NVIDIA's high-performance interconnect protocols: NVLINK, Ethernet, and InfiniBand.

Responsibilities

• Work on a wide range of high-speed, powerful DSPs, silicon photonics IPs, and chips.
• Participate in chip-level features, programming model, and application interface definitions.
• Collaborate closely with analog designers and system architects to develop micro-architecture specifications, calibration, and adaptation algorithms.
• Translate these specifications into RTL and firmware designs.
• Define, build synthesis constraints, and drive timing closure.
• Evaluate PPA trade-offs based on synthesis and P&R feedbacks.
• Participate in silicon bring-up, build testing scripts for debugging, characterization, performance tuning, and production.
• Work with cross-functional teams to ensure successful production.

Requirements

• B.S. or M.S. degree in Electrical Engineering or equivalent experience.
• 5+ years of experience in high-speed digital design.
• Proficient with front-end design flow and tools.
• Good understanding of Verilog or System Verilog, logic design concepts, and typical structures.
• Experience with design for test, timing constraints, and static timing analysis.
• Experience with industry verification methodologies, such as UVM.

Qualifications

• Knowledge of optical transceiver devices and integrated components such as modulators, detectors, and TIAs.
• Experience with SerDes architecture and building blocks such as CDR, DFE, CTLE, TXFIR.
• Experience with digital assist analog designs, such as calibrations.
• Familiarity with mixed-signal circuit design concepts and experience in behavior modeling of mixed-signal circuits.
• Understanding of physical layer and communication protocols, such as Ethernet, InfiniBand, PCIe, and USB.
• Exposure to hardware and firmware co-design.
