## Description

## **ABOUT RETELL AI**

Retell AI is using first-principles thinking to reimagine the call center with cutting-edge voice AI. Thousands of companies now use Retell's AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by Y Combinator, Alt Capital, and other leading investors. We've grown 20x from $5M to $100M+ in annualized revenue run rate in under two years, reaching a $1.5B+ valuation.

Our vision for 2026 is to build a modern CX platform where entire contact centers are powered by AI. Instead of basic automation that needs constant human tuning, we're creating intelligent AI “workers” that act as frontline agents, QA analysts, and managers, continuously executing, monitoring, and improving every customer interaction.

We're growing fast and looking for ambitious builders who want to tackle hard technical problems, move quickly, and have a real impact on one of the fastest-growing voice AI companies in the world.

Let's build the future together.

Retell AI transforms customer experience with voice AI for enterprises, including customers like CVS/Aetna, San Antonio Spurs, Lenovo, and Grab. We have more customer stories than we can tell!

We’re looking for a **Staff Frontend Engineer** to lead complex frontend projects and shape the user experience of our voice AI platform. You’ll build tools that help customers create, deploy, monitor, and improve AI voice agents.

## KEY RESPONSIBILITIES

- Lead frontend projects from concept to production, owning architecture, implementation, and delivery.

- Build responsive, reliable interfaces using **React, TypeScript, JavaScript, HTML, and CSS**.

- Partner with product and design to simplify complex workflows across agent configuration, dashboards, and analytics.

- Shape frontend architecture, reusable components, and patterns that help the team ship faster.

- Improve application performance, accessibility, and reliability as customer usage grows.

- Raise code quality through thoughtful reviews, testing, mentoring, and hands-on technical leadership.

- Work with backend engineers to design APIs and data flows that support a smooth user experience.

- You’ve shipped complex web applications and can explain the technical and product tradeoffs behind your decisions.

- You care about interaction details, usability, accessibility, and performance.

- You’re comfortable taking an ambiguous problem, defining an approach, and driving it through delivery.

- You enjoy writing code, mentoring engineers, and working closely with product and design.

**Bonus points:** Experience building enterprise SaaS, developer tools, real-time interfaces, data visualizations, or AI products.

 

## WHY THIS ROLE

- Real ownership over core systems.

- Direct influence on product and company direction.

- A small, high-caliber team with very little process drag.

- Problems that matter to customers, revenue, and scale.

If you want a role where your decisions visibly shape the company, this is it.
