Device Modeling Engineer

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.
