## What we're building
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.
## The role
You'll make the agents themselves much better.
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 you'll do
- Build browser agents that can complete long, messy workflows in real enterprise tools.
- Improve skills, prompts, context, tool use, and model routing.
- Turn customer failures into evaluations and durable product changes.
- Build verification so an agent cannot claim success without a real deliverable.
- Work directly with customers, inspect the output, and ship fixes quickly.
## You might be a fit if
- 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.
