Major French general contractor for infrastructure and heritage renovation
Léon Grosse is a top-tier French construction group with €720M revenue, operating across metropolitan France and overseas territories. The tech stack—AutoCAD, Revit, SAP, Google Workspace, AWS—is typical for large builders, but adoption of Gemini and Terraform signals early moves toward AI-assisted design and infrastructure-as-code workflows. Hiring velocity is accelerating with 204 open roles (98 in the last 30 days), heavily weighted toward construction and engineering staff, indicating major active project load and likely workforce scaling across occupied-site rehabilitation and energy transition work.
