Expanse Electrical operates a capital-intensive infrastructure business serving transmission and distribution systems across the U.S., combining design, installation, and lifecycle maintenance with 24/7 emergency response. The tech stack—CAD, AutoCAD, Revit, ETAP, Siemens, Schneider Electric, and industrial controls (Allen-Bradley, PLC, HMI)—reflects a heavy engineering-and-design organization; the current hiring surge (22 roles in 30 days, 68% engineering) is concentrated in mid-level design and field positions, suggesting capacity expansion for substation and control-building projects rather than platform modernization.
