El Segundo, CA




This is an opportunity to work at the leading edge of power electronics. Efficient Power Conversion Corp. was the first to introduce and commercialize enhancement-mode gallium-nitride-on-silicon FETs, also known as eGaN® FETs, and remains the leader in gallium nitride-based power management devices. With the recent addition of monolithically integrated GaN power stages, EPC increases GaN performance and widens the advantage over silicon-based power devices. GaN is increasingly adopted in high-performance power conversion applications and enables new applications such as wireless power transfer and LiDAR used in autonomous vehicles and robots.

We are looking for highly motivated people with the ability to identify and develop technological advantages of GaN-based semiconductors in various existing and new applications. Join our team and help develop the power semiconductor technology of the future.

Job Description:

As senior applications engineer you will be part of a world class team designing, programming, and evaluating leading edge GaN-device based digitally controlled converters. You will have the opportunity to publish your work at several internationally recognized peer reviewed conferences, journals, and trade magazines. You will also have an opportunity to work with the top customers in the industry on their leading-edge designs.

This position requires an independent self-starter who pays attention to detail, has excellent organizational skills, a proven track record of success, can generate new ideas, and can work as part of a team. You will enjoy the support of a highly talented team who will assist your career growth and knowledge of GaN FETs and IC’s. The main responsibilities for this position are:

  • Design, simulate, program, evaluate and support various leading-edge high performance, cost-effective digitally controlled reference DC-to-DC converters that exemplify the superior characteristics of eGaN FETs including instructional collateral generation and design for manufacturing (DFM) reviews,
