Nathan Millecam

Co-Founder, CEO


Nathan (Nate) Millecam has over 15 years of experience in the aerospace and aviation industries.

As CEO and Co-Founder of Electric Power Systems, Nate oversees and manages corporate strategic, developmental, and innovation efforts. His 15 years of experience combined with his extensive business knowledge make him an exceptional leader in the industry.

Nate began his professional career as a technology consultant for e-commerce businesses. After completing his M.B.A. at the W.P. Carey School of Business at Arizona State University, Honeywell Aerospace admitted him into its prestigious Leadership Development Program, where he served in a variety of capacities.

Nate gained an interest in electric propulsion while serving as the program manager for Honeywell’s 787 Flight Control Electronics Power System, which included lithium-ion battery systems.  Later, he took on the role of product manager for Honeywell’s electric power systems portfolio, which consisted of generation, distribution, and conversion products.

His experience at Honeywell led him to take a position as the director of strategy and business development at International Rectifier. There, he led merger and acquisition efforts for high-reliability applications. After Infineon acquired International Rectifier, Nate served on the post-acquisition integration team. During this time, he integrated key processes such as sales, inventory, and operations planning; technology roadmap development; annual operation planning/budgeting; and long-term strategic business planning. He later became the director of business management for the high-reliability business unit, where he managed a $200 million portfolio. Products under this portfolio consisted of space-grade converters, power semiconductors, and battery management systems. 

In 2016, Nate and Randy were given the opportunity to spin out many of the energy storage assets from Infineon.  By collaborating efficiently and intelligently, they have been able to develop Electric Power Systems into a premier electric propulsion provider in numerous end markets. 

Nate has a Bachelor of Science in business management from Utah Valley University and an M.B.A. from Arizona State University with an emphasis in operations and finance.  He resides in Logan, Utah with his wife and 4 children. In his free time, he enjoys exercising, the outdoors, and spending time with his family.

Randy Dunn

Co-Founder, Chief Science Officer


Randy’s 35 years of engineering experience in the aerospace industry has proven invaluable to Electric Power Systems and its success in the aerospace industry.

He started his career at McDonnell Douglas (now Boeing), working on projects such as the C-17 Integrated Flight Test Program.  After several years, he transitioned to an engineering manager role at Maxys, where he worked on various International Space Station (ISS) systems at the Kennedy Space Center.  He also ran the processing facility and performed final certification testing on the communications and power quality of the ISS solar array power distribution system. Moreover, Randy worked in coordination with Hughes Space and Communications, including a project focused on the advanced Xenon Ion Propulsion System (XIPS).

In addition to his engineering expertise, Randy is an incredible entrepreneur.  Randy founded Phillips Aerospace in 1997, and this company is now a premier supplier of mechanical components, flight test systems, and avionics for aerospace applications.  Randy then co-founded Evaira (which would later become Electric Power Systems) in 2008 after recognizing the need for more robust energy storage systems in high-reliability markets.  Evaira found work using its energy storage systems for military applications and controllers for micro grids. The group further expanded its energy storage work by moving into medical markets, primarily focusing on mobile CT scan applications.  Randy later sold Evaira in 2011 to International Rectifier, which further pursued battery management circuitry technology. 

Randy received his Bachelor of Science in electrical engineering from Cal State Fullerton.  Randy lives in Orange, CA with his wife Shelly and four kids.  In his free time, he enjoys hiking and walking his three huskies and spending quality time with family.
