Computer use agents to deploy enterprise marketing campaigns. Backed by Y Combinator.
About the role
You'll own the runtime behind every agent run: workers, sandboxes, files, skills, authenticated browsers, durable state, retries, recovery, and the API and CLI around the system. You'll work directly with me and a very small engineering team. Our agents touch customer software and real budgets, so "probably worked" is not good enough.
What they're looking for
- You're a strong full-stack engineer who likes databases, distributed systems, filesystems, and browsers
- You move quickly but care deeply about correctness
- You want broad ownership at an early-stage company
More about this role
Enterprise marketing still runs through agencies because launching one campaign means coordinating specialists across Marketo, HubSpot, Meta, LinkedIn, CMSs, and a dozen other systems. It takes weeks.
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.
