Construction Randolph, Massachusetts 201–500 employees Founded 1914 Privately Held

Cox Engineering designs and installs HVAC systems and sheet metal ductwork for commercial buildings, with growing focus on building automation and controls. The tech stack—Tridium Niagara, BACnet, Modbus, Revit, Procore—reflects a shift toward integrated BAS (building automation systems) alongside traditional fabrication work. Engineering-heavy hiring (11 of 17 active roles) and active projects in BAS design, GUI dashboards, and system turnover suggest the company is scaling technical capabilities to compete on automation and controls, not just mechanical installation.
