Telecommunications infrastructure and enterprise services provider

Telecommunications Dallas, TX 10,001+ employees Public Company
att.com LinkedIn

AT&T operates a large-scale telecom and enterprise services business spanning wireless, broadband, and managed hosting. The tech stack reveals heavy reliance on cloud platforms (AWS, Azure) and data services (Glue, Athena, SageMaker, QuickSight), paired with enterprise middleware (MuleSoft, Salesforce, SAP, Oracle) — a pattern consistent with a sprawling legacy business modernizing through cloud migration and analytics. Active hiring is heavily sales-driven (256 roles), with 297 positions posted in the last 30 days, while engineering remains lean (27 roles), pointing toward a business-execution and revenue-retention focus rather than product innovation.
