BT Group operates fixed, mobile and managed network services, and its stack is dominated by enterprise networking gear (Cisco Viptela, Meraki, SD-Access, Juniper, Fortinet, Aruba) alongside a cloud-native layer of Java, Spring Boot, Kubernetes, AWS EKS and Terraform. Hiring is accelerating and skews senior, with security the second-largest function after engineering, which matches recurring pain points around vulnerability management, incident response and SOX compliance.
