Senior Fullstack Engineer

We’re building an AI-first delivery system where agents ship product features end-to-end, and engineers build the platform (the harness) that makes it safe, reliable, and scalable. This is a hands-on delivery role with a focus on shipping product features. Your day to day: Design and build robust, scalable solutions for complex problems, balancing performance, maintainability, and delivery speed Design and implement agentic workflows that take a requirement from spec → code → review → deploy Produce clean, well-tested, maintainable code across our TypeScript/React/Node stack Use AI coding agent tooling as part of your day-to-day workflow Suggest and implement process or technical improvements that make the team more effectiv What We're Looking For Strong fullstack engineering ability.
