Vertically integrated local energy infrastructure operator across heating, cooling, and power

Renewable Energy Power Generation Boulogne-Billancourt, Île-de-France 5,001–10,000 employees Partnership

IDEX operates France's only end-to-end local energy system—from renewable production (waste, biomass, geothermal, solar) through district heating/cooling networks to building-level optimization. The tech stack reflects dual operational modes: industrial control systems (Wonderware, Rockwell Automation, OPC UA, Modbus TCP/IP) for plant operations, plus modern cloud infrastructure (Kubernetes on Azure, Python/Django, PostgreSQL) for customer-facing optimization and data layers. Engineering dominates the 688-person hiring pipeline, signaling heavy investment in maintenance automation and HVAC system optimization—the core pain point across active projects.
