You will help build the user-facing surface of reView - adata-intensive web application centered on graph-based data, analytics, andinteractive visualization.
The product enables enterprise users to explorecomplex relationships, reason over structured and unstructured data, andinteract with results through high-density dashboards and graph interfaces.The stack is a modern SPA built with React 19,TypeScript, and Vite, talking to a FastAPI backend over REST and streamingAPIs.
The team is small, technical, and focused on solving non-trivial problemsin data modeling, reasoning systems, and UX.
