Hospitals and Health Care Donaueschingen, Baden-Württemberg 1,001–5,000 employees Founded 1989 Public Company

Nexus AG is a decades-old European healthcare software vendor built around hospital information systems (HIS) and specialty diagnostic modules (radiology, cardiology, endoscopy). The tech stack—Oracle, Java, C++, SQL Server, HL7/FHIR—reflects a mature, enterprise-grade codebase. Current project velocity reveals an engineering-heavy org in mid-cycle modernization: the team is refactoring the core HIS platform, building new diagnostic modules, and integrating AI (generative AI chatbot project), while simultaneously wrestling with legacy database structure and internal developer experience tooling.
