About the role
We are looking for a Senior Frontend Engineer with 3-5 years of experience to join one of the fastest-growing voice AI startups in the world. You'll be building the user experiences that power Retell AI's voice automation platform — from dashboards and analytics to customer-facing tools — as part of a small, high-ownership frontend team reporting directly to the CTO.
What will you be doing?
- Building and shipping React-heavy frontend features end-to-end (prompt management, dashboards, analytics)
- Writing production-grade React and TypeScript code — without relying on AI assistance
- Collaborating with backend and full-stack engineers on a team of ~7 frontend-focused developers
- Working directly with customers to onboard, debug, and turn feedback into UX improvements
- Owning frontend architecture decisions and iterating rapidly in a fast-paced startup environment
