NetCologne operates its own telecommunications infrastructure across the Cologne, Bonn, and surrounding regions, serving voice, data, and internet customers. The tech stack reveals a traditional enterprise footprint (SAP, Oracle, Azure, Active Directory) paired with modern development patterns (React, TypeScript, Next.js, microservices architecture) — signaling an active effort to decompose legacy monolithic systems. Active hiring leans engineering-first, with projects centered on fiber-optic expansion, network reliability, and CRM modernization, while pain points cluster around service-process complexity and subcontractor coordination.
