Forward Deployed Engineer, New Grad

Retell is building the AI voice layer for every business.

We’re replacing outdated call centers with real-time AI voice agents that sell, support, and retain customers at scale.

Voice is still the most natural way humans communicate, yet it’s been stuck with legacy tech for decades. We’re changing that by bringing speed, empathy, and reliability to every phone conversation.

In under two years, thousands of companies now run on Retell. We’ve grown to $35M ARR, raised a $4.7M seed, and scaled a 24-person team, backed by Y Combinator, Altman Capital, and top-tier investors.

We’re now one of the top 50 AI apps in a16z’s rankings and a top-ranking startup on the Lean AI leaderboard.

We’re moving fast, tackling hard technical problems, and setting the standard for voice automation. If you want to help define the future of how businesses talk to customers, this is the place to do it.

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.
