Telecom infrastructure and managed services for wireless, fiber, and enterprise

Telecommunications Dallas, TX 10,001+ employees Public Company

AT&T operates a global telecom infrastructure business serving consumer and enterprise customers across wireless, fiber-optic, and cloud-managed services. The tech stack reveals a hybrid multi-cloud architecture (Azure, AWS, GCP) paired with enterprise service-management tools (Remedy, ServiceNow adoption, MuleSoft integration), while the hiring composition—heavily skewed toward sales (1469 roles) with smaller engineering and ops teams—reflects a mature, revenue-focused operating model navigating incremental modernization rather than platform transformation.
