Build and maintain a cohesive UI component library with documentation, ensuring consistency across web apps, device consoles, and dashboards.
Collaborate with engineers to deliver pixel-perfect React (or Vue) interfaces, writing clean HTML5, CSS3 (or Tailwind), and JavaScript/TypeScript.
Run A/B tests and analyze metrics (task completion rates, click paths) to refine designs for performance, clarity, and accessibility (WCAG 2.1).
Work with firmware, backend, and hardware teams to align on feature feasibility, data flows, and security constraints.
Ensure UI meets accessibility standards and can be localized for multilingual support.
