We’re also investing in , a specialized backend service for building AI agents to help engineers debug tasks. Written in TypeScript, Sage is part of our push to bring AI-powered tooling to the heart of our developer productivity ecosystem.

• Design, build, and optimize web applications in React, GraphQL, and TypeScript, focusing on performance and user experience
• Lead development on Spruce and Parsley, delivering data-rich, highly interactive experiences that scale to massive CI workloads
• Collaborate with backend engineers working in Go and TypeScript to build seamless integrations between frontend and backend services
• Contribute to Sage, developing AI-powered agentic flows that help engineers debug tasks more effectively
• Ensure best practices in testing (Cypress), monitoring, and reliability
• Mentor team members and help shape the technical and cultural direction of our team

• 5+ years of strong experience in React and TypeScript
• Experience working with backend systems (experience in a statically typed compiled language like Go is a plus)
