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 scaled to $80M in ARR with a team of 50, up from $5M at the start of 2025, and are now valued at over $1.5B.

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.

ABOUT THE ROLE

Let’s build a beautiful product for Retell.

Retell is building infrastructure and tools that power real-time AI voice agents used by fast-growing companies. We care deeply about making complex, technical workflows feel clear, intuitive, and thoughtfully designed.

As a Product Designer Intern at Retell, you’ll work closely with our designer, engineers, and founders to bring product ideas to life. You’ll take ownership of scoped design projects, moving from early explorations and prototypes to polished experiences that reach real customers.

This is a hands-on opportunity to develop your product thinking, strengthen your visual craft, and learn how great design gets shipped, with guidance and feedback from the team.
