From disconnected data to confident, explainable decisions. data² delivers trustworthy, explainable AI (eXAI) that automates critical workflows and turns complexity into clarity. Our patented, hallucination-resistant eXAI reView platform harmonizes data across your ecosystem delivering real-time actionable insights. Job Description You will help build the user-facing surface of reView - data-intensive web application centered on graph-based data, analytics, and interactive visualization. The product enables enterprise users to explore complex relationships, reason over structured and unstructured data, and interact 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 streaming APIs. The team is small, technical, and focused on solving non-trivial problems in data modeling, reasoning systems, and UX. You will work directly with product, design, and backend engineers across our Mexico City hub and US leadership. Requirements Design and implement user-facing features in React and TypeScript Build and maintain a component-driven UI using modern React patterns (hooks, context, composition) Integrate with the FastAPI REST backend, including authentication flows (OIDC/SSO) Develop complex, interactive dashboards and graph-based data exploration interfaces Work with streaming APIs (ReadableStream/SSE) for real-time and incremental data flows, including LLM-style outputs Ensure performance, accessibility (WCAG AA), and responsiveness across the application Write and maintain unit and component tests Collaborate closely with product and design on scope, trade-offs, and UX details Participate in code reviews and contribute to engineering standards 3+ years building and shipping production web applications Deep experience with React (hooks, state management, component architecture) Experience with Vite, npm, and Git-based workflows Testing experience: unit (Jest/Vitest) and component (Testing Library) Comfortable consuming REST APIs, handling authentication (OAuth/OIDC), and reasoning about caching and network behavior Strong written and spoken English skills for cross-border collaboration Preferred Qualifications Experience building interactive, data-dense dashboards or analytics UIs Data visualization experience with ECharts (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 similar component libraries Experience managing complex client-side state (React Context, reducers, or libraries like Zustand/TanStack Query) Experience with client-side persistence (IndexedDB, localStorage) Performance optimization (Core Web Vitals, bundle splitting, lazy loading, React profiling) Experience integrating with OIDC/SSO providers beyond basic OAuth flows Familiarity with CI/CD systems (GitHub Actions, Azure Pipelines, preview deployments) #J-18808-Ljbffr
