Signal and Power Integrity Engineer

NVIDIA NVIDIA · Semiconductors · Shenzhen, China

NVIDIA is seeking a Signal & Power Integrity Engineer to drive board/system level SI/PI requirements, lead design activities, and collaborate with cross-functional teams. The role involves PCB stackup/material selection, layout review, post-layout analysis, and supporting SI/PI failure analysis. Responsibilities also include developing novel algorithms for SI/PI modeling, supporting customers, and performing VNA & TDR measurements for model correlation. Requires MS/BS in EE or equivalent, 1+ years of SI/PI experience, deep understanding of electromagnetics, proficiency with simulation tools (HFSS, Sigrity, Hspice), and experience with Cadence Allegro. Familiarity with NRZ/PAM-4, interface timing budgets, high-speed I/O, PDN analyses, and scripting languages like Python is a plus.

What you'd actually do

  1. Drive board/system level signal and power integrity requirements
  2. Lead board/system SI/PI design activities, including PCB stackup/material selection, design guide implementation, layout review, and post-layout analysis
  3. Work closely with Architecture, ASIC, Mixed Signal, Package, and PCB Design teams to design and ensure system SI/PI performance meets expectation before Gerber out, also work closely with Design Validation teams to support SI/PI failure analysis
  4. Develop novel algorithms & new methodologies to improve SI/PI modeling efforts
  5. VNA & TDR measurements to support model correlation efforts and improve confidence in design stage
