Job Overview
This is not a traditional support engineering role. This is a strategic, cross-functional position for someone who wants to solve hard problems, design systems that scale, and help people work smarter not just fix what is broken.

We are looking for someone who sees the big picture, thrives in operational complexity, and enjoys enabling others through creative, structured solutions.

Supports end-to-end production network and solutions design review, validation, testing, and operations acceptance for all new or expansion nodes, platforms, or services introduced into T-Mobile’s Voice, Data, Messaging, and Mobile Internet wireless networks. Performs diagnostic investigation into complex customer-impacting network issues to resolve and identify root causes. Provides technical leadership, guidance, and advice to other engineers who are diagnosing, troubleshooting, testing, and operating the network. Evaluates and reports on design, reliability, and maintenance problems to the relevant T-Mobile design or vendor organizations and provides design recommendations to improve the overall customer experience and to drive long-term service improvements. Position serves as primary interface between T-Mobile and its Vendors for technical escalation and problem management of production network issues, and to provide technical solutions for the system and end-users.

In addition to strong technical expertise, we are looking for someone who can think holistically, anticipate operational needs, and guide change across a decentralized environment. The right candidate will enjoy solving complex, unstructured problems and turning them into repeatable systems and tools. You should be confident engaging with stakeholders, building shared understanding, and developing frameworks or solutions that can scale nationally. Success in this role depends on your ability to blend technical depth with creativity, structure, and clear communication.
