Senior Signal Integrity and PCB Quality Engineer

We are looking for a Senior Signal Integrity & PCB Quality Engineer! NVIDIA is powering the next wave of AI and accelerated computing, and our PCB technology is a critical enabler of the world's highest-performance systems. Join our SI team to ensure that every board we ship meets the most demanding signal integrity requirements — from early material research through high-volume manufacturing. You'll work at the intersection of electrical design, PCB fabrication science, and supplier quality, directly impacting products like DGX, MGX, and next-generation GPU/networking platforms. If you love solving complex signal integrity challenges and thrive on bridging the gap between design intent and manufacturing reality, we want to hear from you. What You'll Be Doing: Define board and system level SI requirements with emphasis on PCB impedance control, insertion loss budgets, and high-speed channel performance Lead SI/PI design activities including PCB stackup definition, laminate/prepreg material selection, via impedance optimization, and design review Evaluate and qualify new PCB materials through characterization test vehicles, analyzing Dk, Df, surface roughness, and copper foil properties across frequency Collaborate with PCB fabrication suppliers to establish and monitor SI quality metrics — including trace geometry (H1/H2/W/T), impedance, and insertion loss — for both NPI and mass production builds Develop and maintain statistical process control frameworks for PCB fab impedance and IL data; identify trends, excursions, and root causes Conduct PCB supplier audits to verify…
