Job description

The Device Modeling Engineer is responsible for the development, validation, and release of accurate device models and cells for silicon (Si) and wide-bandgap (WBG) power devices, supporting Power Integrations' product development and technology roadmap.
This role is critical in bridging device physics, characterization, and circuit-level simulation to enable first-time-right silicon, robust product definition, and predictive design across multiple power platforms.
The ideal candidate brings deep expertise in semiconductor device physics, hands-on characterization, and model extraction, with a strong ability to collaborate across device, IC design, product engineering, and applications teams.

Key Responsibilities
Device Modeling & Model Development
Develop, maintain, and release device models and model libraries for Si and WBG (GaN) technologies across multiple voltage and power ranges
Create compact models suitable for circuit simulation (SPICE-level) and system-level design
Ensure models accurately capture static, dynamic, thermal, and transient behavior across operating conditions
Support development of next-generation GaN and high-voltage technologies through predictive modeling
Characterization & Parameter Extraction
Define and execute device characterization plans for model extraction
Perform electrical and thermal measurements, including switching behavior, loss mechanisms, and parasitic effects
Extract model parameters using measurement data and ensure correlation across:
o Process corners
o Temperature and voltage extremes
o System operating conditions
Drive improvements in measurement methodologies and test setups
Simulation & Validation
Perform device-level and circuit-level simulations to validate model accuracy
Correlate simulation vs. measured data and identify discrepancies
Work closely with IC design teams to ensure models are:
o Accurate for design
o Efficient for simulation
o Robust across use cases
Support validation for new product introductions (NPI) and technology releases
Technology & Product Support
Provide modeling support for new device architectures and process technologies
Evaluate electrical and thermal characteristics of GaN and high-voltage power devices
Support failure analysis, reliability studies, and qualification activities from a modeling perspective
Contribute to design reviews and risk assessments for new products
Cross-Functional Collaboration
Collaborate closely with:
o Device engineering
o IC design and layout teams
o Product and test engineering
o Applications engineering
Ensure models meet internal design needs and external customer requirements
Support key customer engagements requiring model validation or customization
Model Infrastructure & Continuous Improvement
Maintain and enhance modeling flows, libraries, and documentation
Improve automation for parameter extraction, validation, and release processes
Drive best practices for model quality, version control, and deployment

Qualifications
Education & Experience
M.S. or Ph.D. in Electrical Engineering (semiconductor devices preferred)
Typical experience:
o Ph.D. + 3+ years, OR
o M.S. + 6+ years, OR
o B.S. + 8+ years
Proven track record in device modeling for Si and/or WBG technologies
