UI Engineer (React) @ Retool

Retool is the fastest way to build internal tools. We're hiring a UI Engineer to work on our drag-and-drop builder, which is one of the most complex React applications in production today. You'll build highly interactive canvas components, improve rendering performance, and work deeply with Recoil and custom React reconciler patches. You need strong fundamentals in React internals — fiber, reconciliation, batching — and a track record of shipping production-grade UI.
