What are the responsibilities and job description for the Senior Product Manager, Growth position at US Mobile?
US Mobile is building the future of wireless communication. The goal: one unified network open to any person and any device, worldwide. Connection without walls.
We’re getting there by empowering customers. All three major networks on one phone and one plan, plus home internet from Starlink. No lock-in. No commitments. Custom fit plans at every price point. 24/7 customer support with real people, empowered to help. We get real-time feedback from Reddit, surveys, and customer support informing product roadmaps and everything we do. It’s working — Consumer Reports named us the top-rated mobile carrier two years in a row.*
And we’re building innovative systems that scale. A network agnostic tech stack. Agile, cross-functional teams built on trust and mutual respect. This work isn’t for everyone. If you work fast, flexibly, and collaboratively — without compromising standards — we want to hear from you.
ABOUT THE ROLE
We’re hiring a Senior Product Manager, Growth to own how people discover US Mobile, sign up, and become long-term customers. You’ll drive measurable improvement across our growth loops by building and optimizing experiments and product changes across our marketing, web and app experiences.
This is a hands-on, high-ownership role. You’ll work directly with engineering, design, data, and growth to find the biggest growth opportunities, ship changes quickly, and build the experiments, channels, and lifecycle systems that compound over time. You’ll be deep in the product, deciding what to build and shipping it.
You’ve built and scaled growth systems before and want to do it again. You’re strong with data and get into it yourself, but you pair that with customer-obsessed product judgment and empathy for users. You move, take ownership and would like to make an impact.
