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

  1. Build browser agents that can complete long, messy workflows in real enterprise tools.
  2. Improve skills, prompts, context, tool use, and model routing.
  3. Turn customer failures into evaluations and durable product changes.
  4. Build verification so an agent cannot claim success without a real deliverable.
  5. Work directly with customers, inspect the output, and ship fixes quickly.

You might be a fit if

  1. You're a strong software engineer who has built with agents, LLMs, or browser automation.
  2. You have product taste and care whether the final output is actually useful.
  3. You like ambiguous problems and fast feedback from real customers. Five days a week in Union Square. $250K to $350K base plus 0.5% to 3% equity. We do not sponsor US visas.
