  • Work with backend engineers to connect presentation layers to APIs, services, data, and enterprise systems.
  • Review implementations and fix visual or functional inconsistencies.
  • Connect UX and development teams while preserving design intent in the implementation.
  • Work with UX designers in Figma to define interactions, responsive behavior, component states, accessibility needs, and design rationale.
  • Surface technical considerations early enough to shape designs before handoff.
  • Match approved designs in production across layout, typography, spacing, hierarchy, interaction, responsiveness, animation, and component behavior.
  • Use AI-assisted tools for coding, refactoring, debugging, prototyping, documentation, accessibility checks, test creation, design-to-code work, and technical exploration.
  • Review AI-generated work for security, accessibility, performance, and maintainability.
  • Create working prototypes for Phase Zero, Art of the Possible, usability testing, and stakeholder demonstrations.
  • Explore interaction models and experiences for mobile and iOS, wearables, VR/XR, mixed reality, spatial computing, immersive technology, and emerging platforms.
  • Deliver commercial-quality interfaces with close attention to pixel-level detail.
  • Meet Section 508 and WCAG standards, using semantic markup, keyboard navigation, responsive design, and inclusive design practices.
  • Keep Figma design-system components aligned with production UI components.
  • Maintain component architecture that is clean, scalable, and documented.
  • Take part in internal design and code reviews before client delivery.
  • Work with UX architects and designers, researchers, accessibility specialists, developers, and technical architects.
  • Explain technical considerations to design and development teams.
  • Join demonstrations, technical discussions, and stakeholder reviews.
  • Contribute shared templates, patterns, documentation, and reusable team resources.
  • Own presentation-layer quality from Figma through implementation.
