About the role

We're backed by Accel, Sheryl Sandberg (former Meta COO)'s venture fund SBVP, and Neo.
Flint takes the manual production off their plate so they get those hours back.
Every single member of the Flint team has been a founding engineer / founder.

building a one-off landing page for every keyword, every campaign change, every A/B test, then waiting on design and engineering to do it.
Today we deliver on-brand pages on your own domain in minutes, with no rebuilds and no engineers.
Imagine a website that builds new pages, tests creative, and optimizes performance in response to real-world signals: competitive shifts, user behavior, trending search queries, the way an autonomous vehicle responds to road conditions and traffic.
You've applied AI to design systems, brand generation, or code generation.

You have deep hands-on experience with prompt engineering, context optimization, and multi-agent orchestration.
