Engineering Services Paris, Île-de-France 201–500 employees Founded 2009 Privately Held

Aventa is an engineering services firm focused on marine energy, offshore transmission, and subsea projects. The stack reflects a heavy CAD/simulation orientation (AutoCAD, BricsCAD, ANSYS, OrcaFlex, ABAQUS) paired with traditional enterprise tooling (Microsoft 365, SQL Server, Java/Spring backends), typical of design-led professional services. Active hiring is 22 roles in the last 30 days across six European countries, with engineering dominating the mix and mid-to-senior splits suggesting both project scaling and experienced hire replacement.
