Job title: Member of Technical Staff, Agent Systems
Job location: New York, NY, US
Job listing URL: https://www.ycombinator.com/companies/characterquilt/jobs/aRdMlOz-member-of-technical-staff-agent-systems
Job description: ## 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. Five days a week in Union Square. $250K to $350K base plus 0.5% to 3% equity. We do not sponsor US visas.
