• Exceptional written communication and design critique skills.
• Strong attention to detail and ability to apply consistent evaluation standards.

• Collaborate with reviewers and stakeholders to refine evaluation standards and processes.
• Incorporate structured feedback and continuously improve scoring quality.
• Contribute to improving AI systems' understanding of design quality, usability, and user experience.
