This role is a highly strategic, executive-facing leadership position within T-Mobile for Business, purpose-built to own and drive the exceptionally complex, high-visibility commercial and operational ecosystem of a single, highly strategic enterprise customer. The Senior Enterprise Customer Success Manager holds end‑to‑end accountability for customer success strategy, serving as the primary executive liaison, commercial intake authority, and orchestration lead across all customer‑facing initiatives.
