Are you in?

Your role Key responsibilities in your new role

Define product concepts and design targets: Translate application and customer requirements into MOSFET specifications and design guidance, balancing efficiency, switching performance, ruggedness, die area, and manufacturability for integrated power products

Perform chip- and system-level simulations: Evaluate MOSFET design features and device–circuit–package interactions using analytical tools, efficiency calculators, and SPICE/Cadence simulations to guide product architecture and design trade-offs

Develop and calibrate SPICE models : Create, maintain, and validate technology and product models, including power MOSFETs and sense FETs, against characterization data to accurately predict device and application behavior

Support cross-functional product development : Collaborate with technology, design, packaging, characterization, and application teams to define experiments, investigate performance gaps, and verify product concepts from feasibility through product qualification.

Advance simulation and development workflows: Develop and maintain custom engineering applications, automation, and data-analysis tools; apply AI-assisted and agentic coding with appropriate verification to improve modeling accuracy, design exploration, and engineering productivity

Your profile Qualifications and skills to help you succeed

5+ years of relevant professional experience in power semiconductor product development, device modeling, or power electronics

A degree in Electrical Engineering, Physics, or a related field , a master’s degree or PhD is preferred

Strong understanding of silicon power MOSFET device physics, electrical characteristics, and design trade-offs, including conduction and switching losses, parasitic, ruggedness, and their impact on voltage-regulator and integrated power-stage performance

Hands-on proficiency in SPICE model development, parameter extraction, calibration, and circuit simulation using tools such as Cadence Spectre, SIMetrix, or LTspice; TCAD simulation experience is a plus

Proficiency in Python, JMP, or comparable programming and statistical data-analysis tools, with experience developing engineering scripts or applications and the ability to use and critically validate AI-assisted or agentic coding workflows.

Strong analytical, problem-solving , and communication skills, with the ability to work independently, document technical conclusions, and collaborate effectively across global, cross-functional engineering teams
