Open positions


EPC is increasing its engineering staff at its Poway, CA offices just north of San Diego.  We develop and manufacture high-power, ultra-compact grid connected conversion systems for a variety of emerging sectors including renewables, energy storage, heavy automotive, and microgrid applications.

We have a passion for high-tech, elegant solutions that deliver outstanding performance and value to our customers.  We love what we do, and we try to foster a creative environment where collaboration is key, experience is valued, and a passion to succeed shows through in everything we do.

Expect a hands-on, highly collaborative environment with a breadth of development tasks in the queue and constant learning around every corner.  Our core engineering team comes from multi-megawatt, medium voltage industries and brings high-power experience to EPC’s lower power applications (40kW to 5MW).

Experience in the industry is strongly desired, but talent and determination are even more desired.  All applicants must have the ability to operate across multiple disciplines in a hands-on, lab-friendly environment, taking designs from concept through testing and then all the way to successful delivery.
