• Partnering with developers on component implementation and performance
• Working closely with product owners to shape and refine design requirements
• Creating accessible components aligned to WCAG standards
• Implementing and managing design tokens

• Leading the full UX lifecycle: research, wireframes, prototypes, and visual design
• Running usability testing, user research, and feedback sessions
• Producing personas, user journeys, and interactive prototypes
• Applying strong UX best practices, including interaction patterns, information hierarchy, and usability principles
• Demonstrating a strong visual design sensibility, with excellent UI composition and layout skills
• Mentoring junior designers and raising the overall design standard
• Staying ahead of UX/UI trends and applying new thinking across products

• Strong visual design sensibility, with excellent UI composition and layout skills
• Expert-level Figma skills
• Strong stakeholder and product collaboration experience
• Comfortable operating at lead level within multi-disciplinary teams
• Basic understanding of HTML and CSS is a plus — stronger skills are beneficial but not essential
