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 — we're The Wirecutter's favorite cellular carrier, and Consumer Reports has 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.

We're looking for a Lead Frontend Engineer to help us build and grow our frontend team as we double our team. This is a high-impact, high-ownership role where you'll manage and mentor a team of engineers while architecting and building fast, accessible, and elegant web and mobile applications used by over 1 million subscribers. Our challenges are both technical and strategic.

About the Role

The Lead Frontend Engineer owns the growth and output of a frontend engineering pod — hiring, developing, and managing a small team — while remaining a strong hands-on contributor and a voice in technical direction. This is a player-coach role: you'll write code and shape architecture alongside your team, not just direct it from a distance, while also partnering with Talent to build out the team and with Engineering leadership to shape where the frontend goes next.

You will:

• Build and lead a team — hire, mentor, and grow a high-performing group of frontend engineers as we scale.
• Shape technical direction — influence architecture, tooling, and roadmap decisions across frontend systems.
• Stay hands-on — architect and build fast, accessible, elegant web and mobile applications used by over 1 million subscribers.
• Scale our systems — help us grow to tens of millions of customers and connected devices.
• Raise the bar — build quality tools and frameworks to ensure a high-quality product.
• Champion accessibility and performance — treat both as first-class concerns across the frontend org.
• Drive innovation — work on mission-critical projects like our next-gen agentic AI chatbot, a customer-centric interface giving full control over phone lines, a next-generation usage dashboard, and an e-commerce experience unmatched in telecom.

Responsibilities:

• Influence technical direction and architectural decisions across frontend systems, balancing pragmatism with long-term scalability
• Build a state-driven UI that adapts seamlessly to network-specific quirks
• Support legacy and new plans simultaneously
• Create elegant, highly accessible (a11y-first
