  • Contribute to and help evolve Lumin’s design system, ensuring consistency, scalability, and brand cohesion across products.
  • Troubleshoot and resolve UI-related issues across browsers and devices, ensuring reliability and accessibility (WCAG/ADA compliance).
  • Stay current with front-end trends, frameworks, and emerging technologies to continuously enhance product usability and developer efficiency.
