Millicom (Tigo) Tech Stack
Regional telecom operator across Latin America with mobile, fiber, and digital services
Millicom operates a multi-service telecom network across Latin America under the TIGO and Tigo Business brands, serving over 46 million subscribers with mobile, fixed broadband, and cable infrastructure. The tech stack reveals a hybrid cloud-native transformation in progress: heavy AWS adoption alongside legacy on-premises systems (VMware, OpenStack), containerization (Docker) being rolled out, and aggressive replacement of legacy workflow tools (ProcessMaker). Sales hiring (131 roles) significantly outpaces engineering (32), indicating a company in growth-and-consolidation mode rather than platform-engineering mode — consistent with their stated pain points around customer acquisition, churn reduction, and sales-target execution.
