Drive supplier corrective and preventive actions (SCAR, 8D, FACA/CAPA) and SPC-based process control at suppliers to reduce defect rates and achieve quality and reliability goals. Work with cross-functional teams to own optics, ASIC, and fabric hardware supply and ensure on-time delivery, cost, quality, and reliability targets are met. Advance supplier and incoming test coverage, including optical power and eye-margin testing, BER and link-level testing, and ASIC functional test, to maximize network fabric reliability. Conduct Source Inspections and supplier process audits, and maintain supplier quality documentation, BOMs, and engineering changes in PLM tools. Establish supplier quality KPIs (incoming DPPM, FAI pass rate, link error and optics failure rates, field failure rate, SCAR closure) and supplier business review cadences, and report performance to leadership.
