Job Overview
T-Mobile is in the midst of a multi-year Oracle ERP and Commerce transformation that is central to how we enable our dealer and partner ecosystem. We are seeking a highly experienced Principal Architect to play a critical role in shaping the architecture, integrations, and long-term strategy of our Oracle ERP and Oracle Commerce Cloud platforms. This role is mostly focused on this transformation for the next two-plus years and is designed for an architect who thrives in complex, ambiguous, and high-impact environments.

Why This Role Matters

This role sits at the heart of T-Mobile's effort to modernize how we onboard, support, and transact with our dealer network.
