Principal Medium Voltage Power MOSFET Design Engineer
Role Summary
Lead design and development of next-generation medium-voltage (MV) shielded-gate trench MOSFET technologies. Work with process integration, applications, marketing, and external foundry partners to convert TCAD-driven device concepts into manufacturable products and support transfer to mass production.
Experience Level
Senior — Principal level. Up to 15 years of experience in power semiconductor device or process development is preferred.
Responsibilities
Primary duties focus on device design, simulation, data analysis, yield improvement, and production transfer.
- Define and establish key process modules for MV shielded-gate trench MOSFET technology.
- Develop and maintain TCAD simulation decks; propose advanced device design concepts.
- Analyze wafer-level electrical test results and package-level performance data for each development iteration.
- Lead yield improvement activities and support technology transfer to mass production.
- Contribute to development of derivative products based on mature technology platforms.
Requirements
Must-have technical skills and experience. Educational qualifications are listed separately.
- Senior-level experience in power semiconductor device or process development, preferably focused on Si-based MV shielded-gate trench MOSFETs.
- Solid understanding of power device physics and semiconductor fabrication processes.
- Hands-on experience with TCAD tools and simulation-based device analysis.
- Experience analyzing wafer-level electrical and package-level performance data.
- Proven track record in yield improvement and supporting industrialization to mass production.
- Ability to work cross-functionally with process integration, application, marketing, and foundry partners.
- Intermediate written and spoken English.
Education Requirements
Ph.D. preferred; M.S. in Electrical Engineering, Physics, or a related technical field acceptable. Related technical degrees or equivalent practical experience in power semiconductor device/process development are considered.
