Infrastructure construction and maintenance across 50 countries with 64,000 employees
Colas operates one of the world's largest infrastructure construction and maintenance networks, with 2,000+ operating units and nearly 45,000 active projects annually. The tech stack is enterprise-standard (Microsoft 365, Azure, Power BI, Tableau) with heavy use of project-management and visualization tools (Microsoft Project, Bluebeam, AutoCAD), reflecting an operations-first culture managing global, multi-site deployments. Active hiring remains broad across construction, HR, and engineering, though velocity is decelerating—a pattern typical of large incumbents managing mature infrastructure rather than building new product lines.
