Principal Analog Engineer for Sustaining Product Engineer

Principal Analog Engineer for Sustaining Product Engineer is responsible for sustaining and continuously improving discrete power MOSFET products throughout their production lifecycle. This role drives manufacturing yield improvement, customer quality support, cost optimization, process transfers, and long-term product reliability for automotive and industrial power semiconductor applications. 

The ideal candidate brings more than 15 years of semiconductor industry experience, including extensive expertise in discrete MOSFET technologies, wafer fabrication, assembly, test, reliability, and high-volume manufacturing environments. This individual will serve as a technical leader, working closely with Product Engineering, Manufacturing, Quality, Reliability, Operations, and major customers to ensure sustained product competitiveness and operational excellence. 

Renesas Electronics is expanding its power semiconductor portfolio to support high-growth markets including automotive electrification, industrial power management, AI infrastructure, and energy-efficient computing. The discrete MOSFET portfolio includes low-voltage and medium-voltage MOSFETs, trench MOS technologies, and advanced power packaging solutions. 

Key Responsibilities 

• Own sustaining engineering activities for released Discrete MOSFET products in mass production. 

• Drive yield improvement through detailed electrical data analysis, defect signature identification, root-cause investigation, and corrective action implementation. 

• Lead customer return investigations and failure analysis activities, coordinating corrective and preventive actions across global teams. 

• Identify and execute cost reduction initiatives including test optimization, assembly yield improvement, wafer cost reduction, and scrap reduction. 

• Support product qualifications, PCNs, process changes, technology migrations, and manufacturing transfers. 

• Monitor key manufacturing indicators, parametric trends, reliability data, and outgoing quality metrics. 

• Drive resolution of cross-functional issues spanning wafer fabrication, assembly, test, reliability, and customer applications. 

• Support product EOL activities, last-time-buy planning, and risk mitigation strategies. 

• Provide technical leadership to global manufacturing sites and serve as escalation point for sustaining issues. 

• Maintain product history, lessons learned, and sustaining engineering best practices.
