Job description

UI/UX Development & Implementation

Translate high-fidelity mock-ups (Figma, Marvel, etc.) into pixel-perfect HTML5 and CSS implementations.

Build React-based chatbot interfaces and complex enterprise forms that handle real-time streaming data.

Implement interactive graph and tree diagrams to represent agent reasoning paths and data structures.

Ensure responsive, accessible, and performant user interfaces across devices and browsers.

Optimize frontend performance for state-heavy applications with complex AI interactions.

Middleware & Backend Integration

Develop and maintain Node.js middleware to manage session enforcement, proxy requests securely, and orchestrate data between UI and backend services.

Partner with backend software engineers to define data contracts and integrate enterprise-grade authentication flows.

Consume and integrate complex backend services (e.g., Spring Boot) using RESTful API patterns.

Implement Server-Sent Events (SSE) or WebSockets for streaming AI responses in real-time.

Technical Architecture & Best Practices

Build scalable, maintainable frontend architectures using modern JavaScript frameworks and design patterns.

Implement state management solutions (Redux) for complex application states.

Develop reusable component libraries and maintain design system consistency.

Integrate frontend build processes and automated UI testing into CI/CD pipelines (Jenkins, GitLab CI).

Package and deploy React/Node.js applications using OCI-compliant containers within orchestrated environments (OpenShift/OCP).

Collaboration & Quality Assurance

Work closely with designers to ensure design fidelity and optimal user experience.

Collaborate with cross-functional teams including backend engineers, UX designers, and product owners.

Implement testing frameworks and maintain high code quality standards.

Participate in code reviews and contribute to continuous improvement of development practices.

Document technical specifications and maintain clear communication with technical and non-technical stakeholders.

• Deep expertise in React and state management solutions (Redux)
• Proficiency in high-fidelity design tools (Figma, Marvel, etc.) for developer handoff and design inspection
• Experience with Node.js to build proxy layers, handle API orchestration, and manage session enforcement and states
• Strong understanding of RESTful API patterns and experience consuming complex backend services
• Experience with data visualization libraries such as D3.js to render complex graph/tree structures
• Familiarity with real-time communication protocols (Server-Sent Events, WebSockets) for streaming data
• Experience with CI/CD pipelines (Jenkins, GitLab CI) and automated UI testing frameworks
• Knowledge of containerization using OCI-compliant containers and deployment to orchestrated environments (OpenShift/OCP)
• Degree or Masters in Computer Science, Engineering, or related field
