## 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 set the architecture and reliability bar for the infrastructure that runs every CharacterQuilt agent.
This is not a narrow platform role. You'll own the system from Postgres and the filesystem through workers, sandboxes, authenticated browsers, and the product state customers see.
## What you'll own
- Worker and sandbox orchestration that stays correct through crashes, retries, and timeouts.
- Durable execution, idempotency, recovery, and observability for consequential agent actions.
- Browser profiles, credentials, tenant isolation, and authenticated session reliability.
- The API, CLI, and MCP surfaces around our agent runtime.
- A simpler system and a higher engineering bar as the team grows.
## You might be a fit if
- You've owned production distributed systems, developer infrastructure, or browser automation.
- You can debug across application code, databases, queues, networks, and filesystems.
- You want staff-level scope without staff-level distance from the work.
