Device Modeling Engineer - San Jose, California, United States
Originally posted 26 February 2026 by the employer.
About the role
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. The role bridges semiconductor device physics, characterization, and circuit-level simulation across power platforms.
What you'll do
- Develop, maintain, and release SPICE-level compact device models and libraries for Si and WBG (GaN) technologies across multiple voltage and power ranges. - Define and execute device characterization plans, performing electrical and thermal measurements to capture switching behavior, loss mechanisms, and parasitic effects. - Extract model parameters from measurement data and validate correlation across process corners, temperature extremes, and voltage conditions. - Perform device-level and circuit-level simulations to validate model accuracy against measured silicon data in collaboration with IC design teams. - Support technology development and new product introduction (NPI) by evaluating GaN and high-voltage power devices, failure analysis, and qualification activities. - Enhance modeling infrastructure, parameter extraction automation, version control, and documentation flows.
What you'll need
- Degree in Electrical Engineering (Ph.D. + 3+ years, M.S. + 6+ years, or B.S. + 8+ years) with a focus on semiconductor devices. - Direct experience in device modeling and model extraction for silicon and/or wide-bandgap (WBG) power technologies. - Working knowledge of semiconductor device physics, including device operation, parasitics, and switching behavior in Si and GaN. - Hands-on experience with high-voltage device characterization and electrical/thermal test systems. - Demonstrated proficiency with Cadence or equivalent simulation environments, including Spectre and SPICE. - Familiarity with compact modeling methodologies, electro-thermal modeling, and behavioral modeling for system simulation.
