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)
