Please Note - Preferred location

Irvine, California. Remote candidates may be considered, provided they are able and willing to travel frequently to Orange County, CA for onsite collaboration, engineering reviews, manufacturing oversight, and key stakeholder engagements.

TAE Power Solutions (TPS) is the electrification spin-off from TAE Technologies, a leader in nuclear fusion technology. The company is leveraging unique power management technology originally developed for nuclear fusion and applying it in adjacent industries including Battery Energy Storage Systems (BESS) and DC Fast Charging for electric vehicles.
