Original job description

US Mobile is on a mission to revolutionize connectivity. Imagine a world where you can go into a single app and buy terabytes of data for every one of your devices: phone, smart devices, car, home broadband, and more. That’s the future that US Mobile is building: a software platform built truly for the 21st century and the age of 5G and IoT, with world class engineering, best-in-class user experience, and features that will define the next generation of connectivity.

At the core of it all, we have a team and culture that has been recognized by Forbes as one of the top 500 best startup employers in the US. Our team spans diverse backgrounds, cultures, and stories, with employees coming from 20+ countries.

We're a venture-backed company entering hypergrowth, having recently ranked 94th on Inc 5000's fastest-growing private companies in America, and we’re looking for someone exceptional to join our team.

The Opportunity

We’re looking for a Senior 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.

\nWhat 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

$160,000 - $250,000 a year
