Computer use agents to deploy enterprise marketing campaigns. Backed by Y Combinator.
About the role
Our agents have to understand a request, use real customer software, create work that is actually good, publish it correctly, and prove what happened. You'll improve that entire loop across browser use, skills, tools, models, and evaluations.
What they're looking for
- You're a strong software engineer who has built with agents, LLMs, or browser automation
- You have product taste and care whether the final output is actually useful
- You like ambiguous problems and fast feedback from real customers

CharacterQuilt uses computer-use agents to do that work inside the software companies already use. A campaign that took three months can now ship in two days. We raised $13M and were one of the fastest-growing companies in YC's P26 batch.
