CSU is a large, privately held facilities-services operator in the Netherlands running 11 regional offices and managing cleaning, food, and event services across healthcare, education, corporate, and hospitality segments. Their tech stack is almost entirely Microsoft-centric (.NET, Azure, Microsoft 365, AFAS ERP), with MuleSoft integration and emerging investments in process automation (Power Automate Desktop, Bicep infrastructure-as-code) — typical of a maturing operations business modernizing legacy systems. Hiring velocity is accelerating, with HR roles outnumbering engineering 4:1, and projects focused on reducing absenteeism, automating cleaning tasks via robotics, and scaling a people-centered culture across a 17,000-person workforce.
CSU Cleaning Services operates across the Netherlands from its base in Uden, serving hospitals, schools, offices, airports, hotels, and event venues with specialized cleaning and facilities management. Founded in 1968 and still family-controlled (management holds ~33% of ownership), the company employs 17,000 staff across cleaning, food, leisure, hotel, airport, and event service lines. The business model combines high-touch labor-intensive operations with recent technology investments aimed at scheduling efficiency, compliance automation, and robotization of repetitive cleaning tasks. Core operational challenges center on staff retention, absence management, regulatory compliance, and customer acquisition in a competitive market.
CSU's core stack is Microsoft-based: Microsoft 365, Azure, .NET, C#, SQL, plus AFAS (Dutch ERP), MuleSoft for integration, Power Automate for workflow automation, and Bicep for infrastructure. Development uses Git, xUnit.net, and Moq for testing.
