Cua (YC X25) is hiring an engineer

Cua is building the infrastructure that lets general AI agents safely and scalably use Computers and Apps like humans do. With 8.9k+ GitHub stars in just 4 months and backing from Y Combinator, we’re providing: An open-source framework for building and evaluating general-purpose AI agents A cloud container platform for sandboxed, scalable agent execution environments A blueprint for what production-grade general agent systems should look like - backed by research We're looking for our first Founding Engineer to help us push this vision forward - turning cutting-edge research prototypes into real, deployable systems. If you’re obsessed with developer tools, infrastructure, and making AI agents go from toy demos to robust, real-world tools - we want to talk. 🛠️ What You'll Work On Day 1 Impact - Ship infrastructure powering real agent workloads used by early customers and open-source users. Agent Infra Core OS-level sandboxing and container orchestration across cloud providers Scalable infrastructure for deploying isolated Linux/macOS environments for agents Tools that make agent deployment as simple as an API call Beyond Engineering Open Source Leadership - Shape our growing GitHub community and help define the standard for AI agent systems Product Strategy - Work directly with the founders on roadmap and direction Dev Advocacy - Help grow the ecosystem with blog posts, community engagement, and in-person events in SF 🎯 You’re a Fit If You… Live and breathe systems - You know how to scale infra, secure containers, and debug hairy cloud issues.
