The Sr Supply Chain Planning Manager
- Network Engineering at T-Mobile is crucial in synchronizing network procurement and deployment plans with prevailing demand and build forecasts, ensuring that inventory levels (including critical spares) across all locations are optimized to meet corporate objectives and network performance targets. This role oversees a significant annual spend within Network Engineering, spearheading requisition processes and securing executive approvals to support ongoing network expansion, modernization, and sustainment programs.

By leading weekly cross-functional meetings with Network Engineering, Operations, Logistics, Finance, and OEM/supplier partners, the manager proactively addresses exceptions, mitigates supply disruptions, and promotes alignment across multiple network portfolios (e.g., RAN, transport, core, IP).
