Responsibilities:
Design, develop, and maintain a large-scale React 18 enterprise SaaS application.
Work independently to deliver features end-to-end, from UI/UX implementation to API integration.
Build and maintain reusable component libraries using MUI v5 and custom design patterns.
Develop complex data visualizations using AG Grid and Recharts for real-time security monitoring dashboards.
Integrate with RESTful backend APIs.
Write and maintain comprehensive tests using Jest and React Testing Library.
Progressively modernize a mature codebase — migrating class components to hooks, classic Redux to modern patterns, and JavaScript to TypeScript where appropriate.
Ensure cross-browser compatibility, performance, and accessibility.
Collaborate with the backend team to maintain backward compatibility across independent deployment cycles.
Use AI tools as a core part of the development workflow to accelerate delivery, improve test coverage, and maintain code quality.
Requirements:
Proven experience (5+ years) as a frontend developer with the ability to work independently.
Expert-level React knowledge (hooks, context, lazy loading, code splitting, lifecycle management).
Strong experience with Redux state management.
Proficiency with MUI (Material UI) v5 and component-based design systems.
Experience building complex data tables (AG Grid or similar) and charting (Recharts, D3, or similar).
Solid understanding of REST API integration patterns (axios, interceptors, token refresh, request cancellation).
Strong testing skills with Jest and React Testing Library (mocking, async testing, provider wrapping).
Experience with SCSS/SASS alongside CSS-in-JS (Emotion/styled).
Proficiency with AI-assisted development tools (Cursor, GitHub Copilot, or similar) — demonstrated ability to integrate AI into daily workflow for code generation, refactoring, and testing.
Strong problem-solving skills, attention to detail, and ability to meet deadlines independently.
Experience with CI/CD pipelines (GitHub Actions, Jenkins) and Docker-based build/deploy flows – advantage
Background in cybersecurity, enterprise admin panels, or SaaS platforms – advantage
