Manager, Fiber Market Development & JV Partnerships you will lead a small, high-impact team responsible for the end-to-end lifecycle of T-Mobile’s fiber market pipeline – from partner origination and data-driven market evaluation to contract negotiation, operational readiness, and commercial launch. T-Mobile’s Broadband business is scaling rapidly across both Fixed Wireless Access and Fiber, and the Fiber portfolio is increasingly defined by the quality of the partnerships we form, the markets we choose to enter, and the rigor of the processes we use to evaluate, approve, and operationalize new fiber builds.
