About Retell AI
Retell AI (YC W24) is reimagining the call center with cutting-edge voice AI. Since launching 18 months ago, 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 scaled to $36M ARR with a team of 20 people, up from $5M at the start of 2025.
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 can act as frontline agents, QA analysts, and managers, continuously executing, monitoring, and improving customer interactions.

About the Role
We're looking for a Senior Product Designer who combines deep UX thinking with strong UI taste. Portfolio is a must. We want to see how you reason through problems, structure complex flows, and arrive at clear, polished solutions.
Retell is building infrastructure and tools that power real-time AI voice agents used by fast-growing companies. Design quality matters here. Every interaction happens in real time, under pressure, with real users. You'll own end-to-end product design across core user workflows, working directly with founders, engineers, and customers to shape features from first principles, not just polish UI after decisions are made.
This is a high-ownership role with real influence over product direction, UX quality, and design standards.
What You'll Do
- Own the product experience end-to-end, from early concepts and PRDs to polished, shipped features used by real customers in high-stakes, real-time scenarios
