About The Position

US Mobile is building the future of wireless communication with the goal of one unified network open to any person and any device, worldwide. They are achieving this by empowering customers with features like all three major networks on one phone and one plan, home internet from Starlink, no lock-in, no commitments, custom-fit plans, and 24/7 customer support with real people. The company utilizes real-time feedback from Reddit, surveys, and customer support to inform product roadmaps. Consumer Reports has recognized them as the top-rated mobile carrier for two consecutive years. They are developing innovative, scalable systems with a network-agnostic tech stack and operate with agile, cross-functional teams built on trust and mutual respect. This role is for individuals who work fast, flexibly, and collaboratively without compromising standards. We’re hiring a Senior Product Manager, Growth to own how people discover US Mobile, sign up, and become long-term customers. This role will drive measurable improvement across growth loops by building and optimizing experiments and product changes across marketing, web, and app experiences. It is a hands-on, high-ownership role where you will work directly with engineering, design, data, and growth teams to identify the biggest growth opportunities, ship changes quickly, and build compounding experiments, channels, and lifecycle systems. You will be deeply involved in product decisions, determining what to build and executing on it. The ideal candidate has a proven track record of building and scaling growth systems and is proficient with data analysis, customer-centric product judgment, and user empathy. This role requires initiative, ownership, and a desire to make a significant impact.

Requirements

7+ years of product management experience, with several years focused on growth — owning acquisition, activation, retention, or monetization.
You’ve built and scaled growth or acquisition systems before, with measurable results.
You own experiments end-to-end and are fluent with product analytics (e.g., PostHog, Amplitude, Mixpanel) — you define the metric, design the test, and read the results yourself.
Strong with data and paired with real-world product judgment and empathy for users; you know when to trust the numbers and when to trust qualitative signals.
You know when to take a big swing with limited data versus optimize what already works, and can explain your reasoning.
You move fast and operate with high ownership in a fast-changing environment.
A strong communicator who can align engineering, design, data, and marketing without formal authority.
You create organization and direction from a set of problems, leading your team towards a clear and well-developed end goal.

Nice To Haves

You’ve built multi-channel acquisition across growth marketing, product-led growth, SEO/ASO, referrals, and lifecycle.
You’ve stood up an experimentation program or culture from scratch.
Experience with pricing and packaging, churn and reactivation, or onboarding optimization.
Background at a high-growth consumer, subscription, or marketplace company.

Responsibilities

Own key growth levers in the discovery, signup, activation and promotional surfaces.
Deliver the highest-impact opportunities across consideration, sign up and life cycle decision points, and then improve them.
Run experiments end-to-end: Form the hypothesis, design the test, ship it, read the results, and roll out what works.
Build and scale growth loops: Optimize engagement and growth loops that compound over time.
Improve activation and retention: Get customers to value faster, and give them reasons to stay.
Partner across the company to ship fast: Work directly with engineering, design, data, and marketing to move growth changes quickly across web and app.
Build the tools growth depends on: Work with engineering on the experimentation setup, event tracking, and lifecycle tooling the team needs to learn from every change.
