M3 Engineering is a 501–1,000-person architecture-engineering-construction firm with deep roots in mining and astronomical infrastructure. The tech stack—AutoCAD, Revit, ETAP, RISA 3D, Civil 3D, and industrial control systems (PLC, DCS, SCADA, Modicon, Wonderware)—reflects a heavy focus on capital-intensive, heavily regulated projects where design precision and regulatory compliance drive tooling choices. Active hiring remains concentrated in engineering roles across US and Chilean offices, with a notable senior-heavy seniority mix, suggesting focus on complex project delivery rather than headcount scaling.
M3 is a privately held full-service design firm founded in 1986 and headquartered in Tucson, Arizona. The firm integrates three disciplines—architecture, engineering, and construction management—and delivers services across the entire project lifecycle from conception through testing and integration. They serve mining, astronomical research, industrial, and infrastructure clients internationally, with offices in Arizona, North Carolina, Mexico, Argentina, Peru, and Chile. Project scope ranges from $100,000 to $1.5 billion in construction value. The professional staff combines architects and engineers with construction management expertise to develop designs tailored to complex client requirements and regulatory environments.
M3 uses AutoCAD, Revit, and Civil 3D for design and modeling; ETAP and RISA 3D for structural and electrical analysis; HEC-RAS for hydraulics; Navisworks for coordination; and industrial control platforms including PLC, DCS, SCADA, Modicon, and Wonderware.
M3 maintains offices in Tucson and Chandler, Arizona; Charlotte, North Carolina; Hermosillo, Mexico; Buenos Aires and Salta, Argentina; Arequipa, Peru; and Santiago, Chile. The firm is also incorporated in Guatemala, Colombia, and Canada.
