· Create responsive experiences for desktop, tablet and mobile devices.
· Simplify complex business processes and improve usability through testing and feedback.
B. AI-First & Conversational User Experience
· Design text- and voice-enabled conversational experiences with clear processing and feedback states.
· Create interfaces that adapt to user intent, permissions, roles and context.

· Develop role-based navigation, dashboards, forms, data tables and approval workflows.
· Optimise performance, accessibility, responsive behaviour and cross-browser quality.
· Collaborate with engineers delivering Python backend services and Azure-hosted applications.
D. Dynamic UI & Intelligent Workspace
· Develop schema-driven interfaces using validated JSON definitions and reusable component registries.
· Implement contextual dashboards, forms, tables and intelligent workspaces.
· Apply approved design systems and safe rendering; never execute unrestricted AI-generated code.
E. AI Avatar & Interactive Digital Assistant Experience
· Support integration of digital assistants with speech-to-text, text-to-speech and streaming interaction.
· Where relevant, integrate Three.js / React Three Fiber and GLB/glTF avatars.
· Support lip-sync, facial animation, avatar states and responsive rendering in collaboration with AI engineers.
F. Enterprise Application & Administrative Interface Design
· Design business process, reporting, analytics, configuration and administrative interfaces.
· Build intuitive experiences for user management, access permissions and operational monitoring.
· Ensure consistent navigation and interaction patterns across modules.
G. Design System, Quality & Collaboration
· Maintain design tokens, reusable UI components, interaction standards and documentation.
· Work with Product Owners, Technical Leads, Full Stack Engineers, AI Engineers and QA Engineers.
· Participate in Agile ceremonies, code/design reviews, testing and defect resolution.
Requirements:
· Bachelor’s degree in Computer Science, Software Engineering, HCI, Interaction Design or a related field; equivalent experience considered.
· Minimum 3 years of UX/UI engineering, frontend development or product interface engineering experience.
· Portfolio demonstrating both UX/UI design and implemented frontend applications.
· Experience building enterprise web applications or SaaS products and collaborating in multidisciplinary teams.
Preferred Skills & Added Advantages:
· Conversational AI, LLM-enabled interfaces, generative AI UX and AI agent interaction patterns.
· Dynamic/schema-driven rendering, real-time streaming and voice-enabled applications.
· Three.js, React Three Fiber, WebGL, GLB/glTF, lip-sync and avatar animation.
