• Design and build production-quality React and TypeScript interfaces for interactive creative workflows.
• Develop backend services using Node.js or Python supporting real users and production traffic.
• Work with REST APIs, WebSockets, Postgres, Redis, observability, and production monitoring.
• Improve workflow performance through latency optimization, queueing, retries, cancellation, error recovery, and user feedback systems.
• Collaborate within a fast-moving team to build, test, deploy, and improve products.

• 3+ years of React and TypeScript product engineering experience with shipped production work.
• Hands-on backend experience with Node.js or Python.
• Experience building complex interactive UI such as editors, canvas tools, node graphs, media tools, or workflow systems.
• Experience with REST APIs, WebSockets, Postgres, Redis, and production debugging.
• Ability to work on-site in San Francisco.

• Experience handling queues, latency, retries, cancellations, and recovery workflows.
• Strong product mindset with the ability to improve user experience.
• Comfortable working in a fast-paced environment and shipping frequently.

Bonus Experience

• Real-time or multiplayer systems, WebSockets, CRDTs, collaborative editors, or live shared state.
