ENSIO deploys digital and energy infrastructure networks for utilities and commercial clients across France, operating at scale with 3,500+ employees. The engineering-heavy hiring mix (63% of active roles) and project backlog centered on power distribution, EV charging, and high-speed networks reveal a company managing large-scale capital deployments. Pain-point clustering around supply chain, cost optimization, and network expansion indicates operational constraints typical of infrastructure contractors scaling into new verticals (photovoltaics, EV charging).
