Device Modeling Engineer

About the role

The Device Modeling Engineer develops, validates, and releases accurate device models and cells for silicon (Si) and wide-bandgap (WBG) power devices, supporting Power Integrations’ product development and technology roadmap. This role bridges device physics, characterization, and circuit-level simulation to enable first-time-right silicon, robust product definition, and predictive design across multiple power platforms.

Responsibilities

• 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.
• 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 process corners, temperature and voltage extremes, and system operating conditions.
• Drive improvements in measurement methodologies and test setups.
• 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 accurate, efficient for simulation, and robust across use cases.
• Support validation for new product introductions (NPI) and technology releases.
• 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.
• Collaborate closely with device engineering, IC design and layout teams, product and test engineering, and applications engineering.
• Ensure models meet internal design needs and external customer requirements; support key customer engagements requiring model validation or customization.
• 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: Ph.D. + 3+ years, OR M.S. + 6+ years, OR B.S. + 8+ years.
• Proven track record in device modeling for Si and/or WBG technologies.

Skills

• Deep understanding of semiconductor device physics (Si and GaN strongly preferred), device operation, parasitics, and switching behavior.
• Strong experience with model extraction and development, high-voltage device characterization and test systems, and CADENCE or equivalent simulation tools (Spectre/SPICE).
• Familiarity with compact modeling methodologies, electro-thermal modeling, and behavioral modeling for system simulation.
