• Build responsive interfaces using HTML5 CSS JavaScript/TypeScript React Angular or applicable modern frameworks.
• Support UI development across responsive web native mobile/iOS SharePoint Sitecore and enterprise platforms.
• Develop reusable UI components interaction patterns design tokens and front-end design-system elements.
• Partner with backend engineering to integrate polished presentation layers with APIs services data and enterprise systems.
• Conduct implementation reviews and directly correct UI inconsistencies when appropriate.

UX-to-Development Liaison

• Serve as the primary technical bridge between UX and development protecting design intent throughout implementation.
• Work directly within Figma alongside UX designers to understand interaction behavior responsive rules component states accessibility requirements and design rationale.
• Identify technical considerations early enough to influence designs before development handoff.
• Ensure production interfaces accurately reflect approved designs across layout typography spacing hierarchy interaction responsiveness animation and component behavior.
• Help eliminate the traditional gap between a polished UX prototype and the final developed product.

AI-Enabled Development

• Actively incorporate AI-assisted development tools into daily workflows to increase speed quality and delivery capacity.
• Use AI to accelerate code generation refactoring debugging prototyping documentation accessibility evaluation test creation design-to-code workflows and technical exploration.
• Use AI to rapidly transform concepts and Figma designs into functional prototypes and proofs of concept.
• Evaluate AI-generated code and output through human technical judgment security requirements accessibility standards performance and maintainability.

• Treat accessibility performance responsiveness and visual quality as part of developmentnot final QA activities.

Figma & Design Systems

• Work proficiently with Figma Auto Layout components variants variables Dev Mode design tokens responsive layouts prototypes and shared libraries.
• Maintain alignment between Figma design-system components and production UI components.
• Contribute reusable components and patterns rather than repeatedly solving the same UI problems.
• Maintain clean scalable documented component architecture supporting both UX and development teams.

Collaboration & Raising the Bar

• Participate in internal design and code reviews before client-facing delivery.
• Collaborate closely with UX Architects UX Designers researchers accessibility specialists developers and technical architects.
