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.

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)
