Job title: Member of Technical Staff, Agent Infrastructure and Reliability

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 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 you'll do - Provision and operate workers and sandboxes. - Make file, skill, and workspace hydration fast and correct. - Build reliable browser authentication and session isolation. - Design retries, replay, cancellation, recovery, and observability. - Ship the API, CLI, and MCP surfaces customers and our own agents use. ## You might be a fit if - 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. Five days a week in Union Square. $250K to $350K base plus 0.5% to 3% equity. We do not sponsor US visas.
