Eos Energy Enterprises builds zinc-powered battery systems - specifically the Z3 line - that compete with lithium-ion on safety and sustainability for utility, industrial, and commercial deployments. The company designs and manufactures domestically, with its headquarters in Edison, New Jersey and production at a facility in Turtle Creek, Pennsylvania. Founded in 2008, Eos has been working the zinc chemistry problem long enough to ship product at scale.
For security practitioners, the attack surface here is physical-cyber converged: energy storage systems that connect to grid infrastructure and industrial control networks across the U.S. The threat model spans operational technology (OT), manufacturing floor systems, and the software layers managing battery performance and fleet telemetry. This isn't a SaaS shop - it's a hardware company where code meets high-voltage DC, and the consequences of a breach extend to grid reliability and worker safety.
The technical culture leans hands-on and data-driven, with an emphasis on continuous improvement and practical problem-solving. If you're interested in defending critical infrastructure that's actively being deployed rather than theorized about, the work at Eos sits at that intersection.
