Principal Engineer, Electrical Design

Job Title

Principal Engineer, Electrical Design

Role Summary

Design and develop switching power MOSFETs for 12V–80V applications across the full product cycle: architecture, device-structure development, TCAD simulation, test and characterization, and collaboration with process integration and IC design teams.

Position sits within device engineering/manufacturing and focuses on delivering manufacturable, high-performance power devices and supporting product yield and reliability.

Experience Level

Senior — requires 7+ years of experience in power semiconductor device engineering.

Responsibilities

Primary responsibilities include:

• Develop high-performance switching MOSFETs leveraging device physics and available manufacturing capabilities.
• Define and optimize device structures and proprietary process flows for performance, ruggedness, reliability, and manufacturability.
• Design and run TCAD simulation experiments to identify critical process and design parameters.
• Collaborate with fab/process engineers to develop new process recipes and design rules.
• Plan and execute process and layout experiments for engineering lots to reduce development cycle time.
• Execute test-mask and product-mask layouts with CAE support and define testing/characterization methods.
• Analyze measured device and test-structure data to optimize design and process; provide engineering support to maintain yield and performance.

Requirements

Must-have technical skills and experience:

• Expertise in power semiconductor devices, device physics, and device reliability.
• Experience with TCAD modeling and simulation.
• Device layout experience and familiarity with mask execution and CAE workflows.
• Experience developing process flows, identifying critical design parameters, and working with fab/process engineers.
• Ability to develop test and characterization techniques and analyze measured device data.
• Understanding of switched-mode power applications, packaging and PCB parasitics impacts on switching, and thermal implications of package/PCB materials; knowledge of MOSFET driver requirements.

Nice-to-have:

• Demonstrated track record of commercially successful power MOSFET developments.
• Direct experience with advanced switching MOSFET structures.

Education Requirements

M.S. or Ph.D. in a relevant technical field (examples: Electrical Engineering, Physics, Materials Science or similar). The posting specifies 7+ years of experience in power semiconductor device engineering in addition to the graduate degree requirement.
