CSG Tech Stack

Cloud billing, revenue management, and customer engagement platform for telecom and enterprise

Software Development Englewood, Colorado 5,001–10,000 employees Founded 1994 Public Company

CSG is a 5,000+ person public company built around billing, revenue management, and customer engagement across telecom, retail, financial services, and healthcare. The tech stack is heavily polycloud (AWS, Azure, GCP all in active use) with Java, Kafka, and SQL-family databases at the core, but hiring is overwhelmingly engineering-focused (107 of 192 open roles), with notably light investment in data (8 roles) and product (6 roles) — suggesting a mature platform in optimization and operational scaling mode rather than feature expansion. Active projects cluster around quote-to-billing automation and custom data model extensions, while pain points center on production stability and incident resolution.
