Senior Signal & Power Integrity Engineer

Job Title

Senior Signal & Power Integrity Engineer

Role Summary

Join the SI/PI engineering team to define and verify signal and power integrity for NVIDIA packages, PCBs and systems. You will collaborate with architecture, ASIC, mixed-signal, package and PCB teams to ensure I/O, clock and PDN performance across board, package and system levels.

Experience Level

Senior — requires experienced engineer with 5+ years of relevant industry experience in SI/PI and hardware design.

Responsibilities

Accountabilities include design, simulation, verification and lab validation of low-speed I/O and PDN across package/board/system domains.

• Design low-speed I/O channels (clock circuits, DDR/memory, sensitive signals) and transmitter/receiver equalization schemes.
• Define PCB stack-ups, materials, layout guidelines and perform layout reviews for packages and PCBs.
• Perform SI/PI simulations (2D/3D EM and time-domain) and co-simulations with circuit and PDN models.
• Run lab measurements using VNA, TDR and oscilloscopes; validate models against measurements.
• Collaborate cross-functionally with architecture, ASIC, mixed-signal, package and PCB teams to meet system-level SI/PI targets.
• Produce guidelines and reviews for switches, adapters and electro-optical modules.

Requirements

Concrete technical skills and experience required; preferred items listed separately.

• Must-have: 5+ years relevant SI/PI experience focused on low-speed I/O and PDN design and analysis.
• Must-have: Expert in low-speed I/O design concepts, clock circuits, DDR/memory interfaces, and equalization techniques.
• Must-have: Proficiency in time-domain analysis and related simulation tools; strong understanding of transmission-line theory and via behavior.
• Must-have: High proficiency with electromagnetic simulation tools (examples: Ansys EM, CST) and 3D/2D EM solvers.
• Must-have: Hands-on lab experience with VNA, TDR and scope-based measurements.
• Must-have: Ability to operate in a fast-paced, multi-discipline engineering environment.
• Nice-to-have: Time-domain co-simulation of I/O circuits with PDN models; familiarity with NRZ/PAM-4 signaling.
• Nice-to-have: Experience with MATLAB, Python and C for analysis and automation.
• Nice-to-have: Advanced academic qualifications (M.Sc. or Ph.D.) in a relevant field.

Education Requirements

Required: B.Sc. in Electrical Engineering or equivalent practical experience. Preferred: M.Sc. or Ph.D. in Electrical Engineering. Related technical fields and equivalent industry experience accepted.
