Front End Developer

Overview: We are seeking Frontend Developers to build a React SPA web app. You will integrate with Python backends with APIs that orchestrate agentic AI workflows using LangGraph, delivering real-time, accessible, and performant user experiences. Strong React, TypeScript, state management, and streaming integrations (SSE/Web Sockets) are essential. Experience with MSAL/SSO, testing (Jest/RTL/Playwright), accessibility, and Azure CI/CD required. Experience with AI-fueled coding with GitHub Copilot or Windsurf is a plus. Responsibilities: Key Responsibilities - Develop the main web application UI in React, implementing designs from the HR UI/UX team. The design artifacts would be from Figma, Sketch - Build and optimize complex, interactive flows that visualize progress and results from agentic AI workflows (e.g., streaming outputs, step-by-step status updates, Planning Logs). - Integrate securely with Python Fast API/LangGraph services via REST/WebSockets/Server-Side Events, handling streaming responses, Session and State Management - Deliver production-quality code with tests (unit, integration, and E2E), enforce accessibility, and meet Core Web Vitals performance targets. - Collaborate closely with AI Engineers to design contracts for workflow events/payloads and with the Designer on component libraries and interaction patterns. - Establish CI/CD pipelines, feature flags, and telemetry; monitor user experience via Application Insights/Matomo Analytics. - Write clear documentation and code comments; participate in code reviews and sprint ceremonies. - Optionally leverage AI-assisted coding tools (e.g., GitHub Copilot, Windsurf) to increase velocity while maintaining code quality. Requirements: Required Technical Skills and Proficiency Levels - JavaScript/TypeScript - React: hooks, context, SSR/SSG awareness - Next.js or Vite-based React app - State Management: Redux Toolkit or Zustand + Async data: TanStack Query/React Query - CSS Modules: Experience with modular CSS architecture and component-scoped styling - Styling: Tailwind and Material-UI component libraries - Authentication/Authorization: MSAL, OAuth2/OIDC, JWT and familiarity with Azure Entra - API Integration: REST, Web Sockets, SSE; streaming UIs; backoff/retry; cancellation - Testing: Jest, React Testing Library + E2E: Playwright or Cypress - Accessibility: WCAG 2.1 AA, keyboard nav, screen readers, color contrast - Performance: profiling, code-splitting, memoization, Core Web Vitals - Enterprise State Management: Complex state orchestration across multi-step workflows and real-time updates - Security: OWASP Top 10, CSP, sanitization, dependency hygiene - Build/DevOps: GitHub Actions/Azure Pipelines, code splitting, environment configs, Azure App Services - Observability: Application Insights and Matomo, logs/metrics/traces, client error reporting Nice-to-Have Skills - Familiarity with Web socket or SSE concepts and event models; designing UIs for long-running, multi-step AI workflows and streaming responses. - Experience with Azure ecosystem: Azure AD, Microsoft Graph API, Azure OpenAI streaming behaviors, Azure Storage/CDN. - Microsoft 365 Integration: Deep experience with Microsoft Graph, Teams, Outlook, and SharePoint APIs - Data visualization: Proficient (Recharts, ECharts, or Visx) for workflow status, timelines, and analytics. - Real-time collaboration patterns (optimistic UI, conflict resolution). - Familiarity with JFrog for artifact and dependency management - AI pair-programming tools: Experience with GitHub Copilot or Windsurf is a plus (optional).
