Jan De Nul Group Tech Stack

Marine construction and dredging for offshore energy, ports, and land reclamation

Construction Capellen 5,001–10,000 employees Privately Held

Jan De Nul Group operates large-scale dredging, marine construction, and offshore energy infrastructure projects across Europe and Asia. The tech stack reveals a heavy reliance on desktop CAD/PLM tools (AutoCAD, Siemens NX, PTC Windchill) and enterprise project management (Oracle Primavera, SAP PM, IBM Maximo) — typical of asset-intensive construction firms — paired with recent investment in custom development (C#, ASP.NET, Angular, Azure DevOps). Hiring is slowing but concentrated in engineering (60 roles), suggesting a shift toward digital tooling and process optimization rather than headcount expansion.
