About the role

  • Flint runs background agents that make changes to real codebases and serves AI-generated pages at scale.
  • It's a 0-to-1 role: you'll inherit a scrappy setup and make it production-grade.
  • The concurrency and coordination problems of running many background agents in parallel, the core hard problem of this role.

Responsibilities

  • 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.
