Join a fast-growing energy technology company as it brings a flagship battery energy storage system (BESS) from development into high-volume production. In this highly visible role, you’ll sit at the intersection of mechanical, electrical, manufacturing, and supply chain—owning the mechanical design, routing, packaging, and integration of complex wire harness systems. Your work will directly shape reliability, manufacturability, and deployment readiness at grid scale.
