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

Requirements:
- Proven ability to influence technical direction and drive architectural decisions at a team or organizational level.

- A strong eye for UX/UI detail, accessibility, and responsive design.
- 12+ years of frontend engineering experience building production‑grade UIs, including experience in a technical leadership or people management role.
- Bachelor's degree in Computer Science, Engineering, or a related technical field.

- A self‑starter who can define and deliver high‑leverage solutions with minimal oversight.
- Demonstrated experience managing, mentoring, and growing frontend engineers, including hiring and performance management.
- Experience partnering with Talent/Recruiting to build and scale engineering teams — defining roles, running hiring processes, and closing candidates.
- Strong stakeholder management skills — able to represent frontend engineering’s perspective persuasively in front of executives, PMs, and cross‑functional partners.
