Job description

• 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
• 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
• 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) interfaces that work across platforms
• Lead and contribute to building modern frontend 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
• 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
• Set and uphold engineering standards and best practices across your team
• Manage, mentor, and grow a team of frontend engineers — owning hiring decisions, performance management, career development, and day‑to‑day team health
• Partner closely with Talent/Recruiting to define hiring needs, shape interview processes, and build out the frontend engineering team as we scale

Benefits

• Gym reimbursement
• Free cellular service on the best network in the US
• Free lunch in NYC office & fully stocked kitchen
• Metrocard reimbursement
