Retell AI
Supercharge Your Contact Center Operations with AI Phone Agents
GTM Engineer - Growth Experiments
About the role
Your experiment backlog looks like this:
- Stand up cold calling infrastructure and test it as a channel
- Build callback flows — AI collects consent, Retell agent calls them back
- Turn anonymous website visitors into actionable leads
- Test gifting as a conversion lever
- Explore marketplace listings and partner directories
- Build a self-serve pilot program page — click, buy, start
- Run ads for free pilot programs and measure CAC
- Launch vertical-specific outbound and ABM plays
- etc etc
You're a fit if:
- You're a builder who gets bored maintaining — you want to test new things constantly
- You can code or script (Python, SQL, JavaScript) enough to build real tools, not just configure SaaS
- Good taste for which experiments are worth running and which are noise
- You move fast — idea to live test in days, not weeks
- You've worked at a startup where you figured things out, not followed a playbook
About Retell AI
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We’re replacing outdated call centers with real-time AI voice agents that sell, support, and retain customers at scale.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.
