Civil engineering and construction management across the Midwest
Gonzalez Companies operates a mid-sized civil engineering and construction management practice across six states in the Midwest, with roots in water infrastructure, transportation, and treatment facility design. The tech stack is heavily weighted toward specialized engineering tools—AutoCAD Civil 3D, Revit, WaterGEMS, SewerGEMS, HEC-RAS—paired with project and resource management layers (Procore, Oracle Primavera, Viewpoint), suggesting a firm optimizing for complex hydraulic and infrastructure modeling. Active hiring remains concentrated in engineering roles with a seniority split favoring senior and junior talent, while pain points around leadership retention and M&A integration indicate organizational scaling challenges.
Founded in 1999, Gonzalez Companies is a partnership-structure civil engineering and construction management firm headquartered in St. Louis with satellite offices in Chicago, Belleville, Salem, Louisville, Dayton, and Cincinnati. The firm serves public and private sector clients across the Midwest, with deep specialization in water distribution and sewer collection systems, treatment facilities, pump stations, and transportation infrastructure. Project work spans hydraulic modeling, pipeline design, and complex wastewater systems. The 51–200 person organization is actively hiring across engineering and transportation disciplines, with current openings reflecting growth in both technical and leadership capacity.
