Front-End Engineer

You will help build the user-facing surface of reView - a

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.

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

and component (Testing Library)

Comfortable consuming REST APIs,

handling authentication (OAuth/OIDC), and reasoning about caching and network

behavior

Strong debugging skills using browser

developer tools

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)

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
