About The Position

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. This role is the functional leader responsible for all three. As the Sr. 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. You will manage a team of analysts, GIS specialists, and operations coordinators, and you will be the primary point of accountability for ensuring that T-Mobile’s fiber footprint grows in the right markets, with the right partners, on the right terms. You will be the source of truth across our partner relationships and be directly accountable for the pace and quality of T-Mobile’s fiber market expansion.
