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.
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 (eg, 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 (eg, GitHub Copilot, Windsurf) to increase velocity while maintaining code quality.
Required Technical Skills and Proficiency Levels
- 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).
