Eos Energy Enterprises, Inc. Tech Stack

Long-duration zinc battery systems for grid and industrial energy storage

Energy Technology Edison, NJ 501–1,000 employees Founded 2008 Public Company

Eos Energy manufactures aqueous zinc batteries and grid-scale energy storage systems for utility, industrial, and commercial customers. The tech stack is deeply hardware-focused—Allen-Bradley, Siemens, PLC controllers, CAD/CAM tools (SolidWorks, AutoCAD), and power systems modeling (PSCAD, MATLAB)—reflecting a capital-equipment manufacturer rather than a software company. Hiring velocity is accelerating with engineering and manufacturing roles leading; the pain-point list centers on manufacturing efficiency (waste reduction, throughput, downtime, process variation), signaling a company scaling production operations post-commercialization.
