• Solid understanding of accessibility standards and practical experience implementing them, including inclusive keyboard navigation patterns.

• Translate research insight into well-structured tickets for the development backlog, covering both defects and improvements.
• Champion accessibility as a built-in constraint rather than a retrofit, ensuring all features meet recognised accessibility standards.
• Contribute to and maintain design documentation.
• Work upstream of ticket refinement sessions to bring UX input into the process early rather than resolving issues within scheduled calls.
• Collaborate closely with development teams, including colleagues based in various locations and time zones, to bridge design and development.
