Tenant Onboarding Specialist

Job Description

Why this job matters

Network Cloud is BT’s private, OpenStack‑based cloud platform, providing the secure and resilient foundation on which critical BT and third‑party network functions are deployed. As the platform continues to grow, the way new tenants are onboarded has a direct impact on the security, resilience, and compliance of the entire environment.
The Network Cloud Onboarding team is responsible for ensuring that tenants are integrated into Network Cloud in a consistent, secure, and supportable way from day one. This role sits at the heart of that onboarding process, owning the delivery of network connectivity and ensuring that designs, interconnects, and security controls are correctly implemented before services go live.
A key driver for this role is Interstellar, BT’s strategic programme to achieve and sustain compliance with the Telecom Security Act (TSA). New tenant onboarding is a critical control point for TSA, and this role ensures that secure‑by‑design networking principles are embedded upfront. By enforcing approved architectures, segmentation, firewalling, and controlled connectivity, the role reduces risk across shared infrastructure and prevents legacy or non‑compliant designs from entering the platform.
Working closely with tenants, platform engineering teams, and network service providers such as Omninet and 21C, the Cloud Network Engineer enables tenants to consume Network Cloud services quickly and safely without compromising existing workloads. This includes ensuring that all new connectivity aligns with governance standards, operational models, and long‑term support requirements.
