About this role
About Sable
Sable built Aidan, the first AI employee who can lead customer calls using realtime voice, vision, and browser use. Aidan runs a live, two-way conversation inside a real product environment, clicking through the product like a human, watching the user's screen, and adapting the journey on the fly. Every conversation feeds a self-improving context graph we call the Brain, so Aidan gets smarter with each call.

What you'll do
Design evaluations for voice, vision, and browser use to direct and accelerate improvements in the agent, context, and models
Build and maintain our internal benchmarks and simulations
Work on systems to score customer-specific scenarios and identify gaps in current capabilities.
Who you are
Engineer with statistics and/or applied machine learning experience
