R&D Engineer

Vishay Intertechnology, Inc.•San Jose, CA

About The Position

Vishay is seeking an R&D Engineer to lead innovation in advanced MOSFET technologies across its power and/or logic semiconductor portfolio. The role focuses on next-generation device architecture, performance optimization, and technology strategy. It is based in the Greater Phoenix Area, Arizona, with limited travel potentially required to support collaboration with manufacturing facilities, technology centers, suppliers, customers, and other engineering organizations. The engineer develops and optimizes power MOSFET device structures and technologies to meet electrical, reliability, cost, and manufacturability requirements. The role applies semiconductor device physics, modeling, simulation, and device characterization to improve performance and efficiency, and contributes to device concepts, technology roadmaps, benchmarking, and long-term R&D strategy. The engineer leads technical projects and collaborates across engineering, manufacturing, quality, reliability, applications, and operations teams, including global Vishay organizations. Candidates should have a Ph.D. in Electrical Engineering, Materials Science, or Physics focused on semiconductor devices or device modeling. Candidates with a master's degree and at least three years of relevant industry experience may also apply. Vishay describes its benefits as a comprehensive suite of health care coverage, financial support programs, and other resources, alongside career development opportunities and an open, collaborative culture.
