We're looking for a Senior React Developer to help build an intuitive, data-dense user interface for our SaaS platform, working closely with backend and design teams to turn complex data and workflows into clear, usable experiences.
< dir="ltr">Responsibilities>Build and maintain the React application UI: dashboards, detailed data views, and multi-step workflows
Design components for dense data (tables, charts, drill-downs) that stay clear and performant with large datasets
Build interactive data visualizations using libraries such as Recharts, Visx, or ECharts
Work closely with backend engineers to consume APIs, shape data contracts, and handle async/long-running operations
Implement robust state management for complex, multi-step workflows
Ensure UI correctness for data display — formatting, rounding, and precision must exactly match backend calculations
Build responsive, accessible interfaces for a professional user base
Write unit and integration tests (React Testing Library, Jest/Vitest, Cypress/Playwright) for critical UI flows
Collaborate on API design and participate in code reviews and architecture discussions
5+ years professional experience with React, including hooks, context, and modern state management (Redux Toolkit, Zustand, React Query/TanStack Query, or similar)
Strong experience with TypeScript in a production React codebase
Experience building data-heavy UIs: tables, dashboards, filters, drill-downs, exports
Experience integrating with REST APIs, including handling pagination, async/long-running jobs, and error states gracefully
Experience with a charting/visualization library (Recharts, Visx, D3, Chart.js, or similar)
Strong attention to detail with numeric/data formatting and precision
Familiarity with testing frameworks for React (RTL, Jest/Vitest) and end-to-end testing tools
Experience building UIs for regulated, compliance-sensitive, or high-accuracy domains
Experience with design systems and component libraries (e.g., Tailwind, MUI, or a custom design system)
Experience with role-based access control / permissioning in enterprise applications
Experience collaborating with FastAPI or similar Python backends
Exposure to exporting data to Excel/PDF from the frontend
