Are you ready to be part of the Un-carrier journey at T-Mobile?

We are seeking a Sr. Technical Product Manager to define and design the foundational APIs that sit at the center of TFB Engineering’s long-term technology vision. This work is critical to our 2026 strategy and directly enables seamless, plug-and-play integration with our growing ecosystem of third-party partners. The capabilities you build here unlock faster partner integrations, accelerate net add growth, and protect the velocity of our most strategic in-flight programs.

This role operates at the intersection of customer needs, technical feasibility, and business strategy. You will own the full product lifecycle from concept through delivery for scalable, durable, future-proof API capabilities. You will partner deeply across business and engineering teams to secure alignment, drive execution, and deliver high-impact platforms and services that produce measurable business outcomes.

A successful candidate is a strategic thinker and hands-on leader who blends customer empathy, technical depth, and business acumen. You define product strategy and roadmaps, lead end-to-end delivery, anticipate industry direction, and bring cross-functional teams along for the ride. You will write capabilities and features that translate strategy into actionable engineering work, run agile ceremonies, manage backlog priority, and represent the product to executive leadership and external partners. You will also take accountability for the financials of your initiatives, including time entry, Jira hygiene, and capitalization impact.

Our team operates like a startup inside T-Mobile. Everyone is an owner, everyone has agency, and we break down barriers between business and IT to deliver. The pace is high, the work is meaningful, and no two days look the same. If you're up to the challenge, apply today.
