Required Qualifications:

  • Strong proficiency in HTML5 and CSS3, including semantic markup and modern layout techniques (Flexbox, Grid).
  • Good understanding of responsive design, mobile-first development, and cross-device compatibility.
  • Familiarity with accessibility standards (WCAG), ARIA basics, and inclusive UI practices.
  • Ability to review and critique frontend code for clarity, structure, and best practices
  • Interest in contributing to the improvement of large-scale AI systems and foundational models.
  • Basic understanding of frontend workflows and design-to-code translation is a plus.
