About
Justin Lopas is co-founder and COO of Base Power, leading manufacturing and operations as the company scales home battery deployment across Texas and toward a domestic factory. Before Base, Lopas was one of the first four engineers at SpaceX's Starbase site in South Texas, where he led manufacturing engineering on Falcon thrust structures and worked on Starhopper, the first Starship prototype. He earned a mechanical engineering degree from the University of Michigan before joining SpaceX. Lopas applies the SpaceX manufacturing playbook of vertical integration and rapid iteration to grid hardware, with the goal of pulling battery production back onshore.
