Underground natural gas storage operator transforming infrastructure for renewable gases

Oil and Gas La Garenne-Colombes, Île-de-France 1,001–5,000 employees Privately Held

Storengy operates 21 underground gas storage sites across France, Germany, and the UK, with a 70-year track record in subsurface exploration and exploitation. The tech stack is Microsoft-centric (365, Teams, Power Automate, Azure, Copilot) paired with Python and Power BI, reflecting an organization in the early stages of digitizing legacy industrial operations. Hiring is heavily weighted toward interns and operational roles—78% of open positions are entry-level or ops-focused—signaling either a major onboarding initiative or structural gaps in mid-level talent; this pattern aligns with active projects around integrated management systems, CSRD compliance, and maintenance optimization rather than deep technical infrastructure builds.
