BT Group Tech Stack

National telecom operator scaling cloud infrastructure and security operations

Telecommunications London 10,001+ employees Public Company

BT Group operates Britain's primary telecommunications backbone, serving millions across fixed, mobile, and managed services. The tech stack reveals infrastructure modernization underway: heavy adoption of containerization (Docker, Kubernetes) and infrastructure-as-code (Pulumi, Terraform, CloudFormation) alongside SAP S/4HANA migration, while engineering hiring (59 roles) outpaces sales (11) by 5:1—a pattern typical of companies shifting from service-delivery cultures toward platform and automation engineering. Active pain points around legacy migrations, SLA compliance, and security gaps align with the hiring velocity in security (19 roles) and engineering.
