Full job description

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.

The Opportunity

We’re looking for a Staff Front-End Engineer to join our growing engineering team as we scale from 14 to 24 developers. This is a high-impact, high-ownership role where you’ll architect and build fast, accessible, and elegant web and mobile applications used by nearly 1 million subscribers across Verizon, AT&T, and T-Mobile. Our challenges are both technical and strategic.

What you'll do:

Build a state-driven UI that adapts seamlessly to network-specific quirks.
Support legacy and new plans simultaneously.
Create elegant, highly accessible (a11y-first) interfaces that work across platforms.
Work on mission-critical projects, like our next-gen agentic AI chatbot that’s redefining how customers interact with mobile support such as: Customer centric interface enabling total control over your phone lines, a next generation dashboard to monitor your usages and create an e-commerce expereince that's unmatched in Telco!!
Lead and contribute to building modern front-end features using React, TypeScript, and CSS.
Design and build UI components for both web and React Native applications.
Architect scalable systems to support millions of user interactions across different networks.
Champion accessibility (a11y) and performance as first-class concerns.
Collaborate closely with backend, product, and design teams to drive elegant, data-informed solutions.
Work with emerging technologies like Rust where performance or architecture demands.
Drive and mentor a high-autonomy, high-impact engineering culture.

Qualifications:

8+ years of front-end engineering experience building production-grade UIs.
Proficiency in TypeScript, React, and CSS-in-JS or equivalent styling approaches.
Experience with state management and data fetching libraries (e.g., Tanstack Query, Redux, Zustand).
A strong eye for UX/UI detail, accessibility, and responsive design.
Comfort dealing with complexity: legacy code, varied device support, and cross-platform consistency.
A self-starter who can define and deliver high-leverage solutions with minimal oversight.
Bonus: Experience with Rust, mobile development (React Native), or telecom-related apps.

Benefits:

Competitive Salary
Gym reimbursement
Commute reimbursement
Flexible working hours
Subsidized health benefits (Medical, Dental, Vision)
Professional development stipend
Flexible time off

These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
