Senior Signal Integrity and PCB Quality Engineer

Responsibilities

• 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 process capability, compliance with NVIDIA specifications, and continuous improvement initiatives
• Partner with cross-functional teams (layout, mechanical, reliability, procurement) to balance SI performance with manufacturing feasibility, cost, and reliability
• Contribute to PCB technology roadmap development, evaluating emerging materials and fabrication processes for next-generation products
• What We Need to See
• BS or MS in Electrical Engineering, Materials Science, Chemical Engineering, or a related field, with 5+ years of relevant experience in PCB SI or PCB fabrication
