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. You will work directly withproduct, design, and backend engineers across our Mexico City hub and USleadership.Requirements- Design and implement user-facingfeatures in React and TypeScript- Build and maintain a component-drivenUI using modern React patterns (hooks, context, composition)- Integrate with the FastAPI RESTbackend, including authentication flows (OIDC/SSO)- Develop complex, interactivedashboards and graph-based data exploration interfaces- Work with streaming APIs(ReadableStream/SSE) for real-time and incremental data flows, includingLLM-style outputs- Ensure performance, accessibility(WCAG AA), and responsiveness across the application- Write and maintain unit and componenttests- Collaborate closely with product anddesign on scope, trade-offs,



and UX details- Participate in code reviews andcontribute to engineering standardsRequirements- 3+ years building and shippingproduction web applications- Strong JavaScript and TypeScript,including generics, discriminated unions, and strict typing- Deep experience with React (hooks,state management, component architecture)- Solid HTML/CSS fundamentals: semanticmarkup, responsive design, accessibility (WCAG AA), modern CSS (flexbox, grid)- Experience with Vite, npm, andGit-based workflows- Testing experience: unit (Jest/Vitest)and component (Testing Library)- Comfortable consuming REST APIs,handling authentication (OAuth/OIDC), and reasoning about caching and networkbehavior- Strong debugging skills using browserdeveloper tools- Strong written and spoken Englishskills for cross-border collaborationPreferred Qualifications- Experience building interactive,data-dense dashboards or analytics UIs- Data visualization experience withECharts (or similar: D3, Recharts, Plotly)- Experience with graph visualization(e.g., React Flow, Cytoscape, Neo4j NVL) or graph data models (Cypher)- Experience with streaming APIs (SSE,ReadableStream) for real-time or LLM-style flows- Familiarity with PrimeReact or similarcomponent libraries- Experience managing complexclient-side state (React Context, reducers, or libraries like Zustand/TanStackQuery)- Experience with client-sidepersistence (IndexedDB, localStorage)- Performance optimization (Core WebVitals, bundle splitting, lazy loading, React profiling)- Experience integrating with OIDC/SSOproviders beyond basic OAuth flows- Familiarity with CI/CD systems (GitHubActions, Azure Pipelines, preview deployments)
