## About the role

Sixtyfour turns a single name, email, or domain into a full, verified picture of a person or company — by sending AI agents out to research the open web the way a sharp analyst would, then checking and scoring what they find. You'll build real parts of that: the agents that reason and gather evidence, the systems that run them at scale, and the product people use to see the results.

## What they're looking for

- You move fast, own your work, and can work in person in San Francisco
