• Incorporate feedback from senior reviewers and continuously refine evaluation approaches.
• Assess designs from the perspective of usability, accessibility, visual quality, interaction patterns, business objectives, and end-user needs.

Requirements

• 5+ years of professional experience in product design, UI/UX, UX design, or design systems for real-world digital products.
• Experience working with leading digital-product or UX studios, product-led organizations, e-commerce platforms, marketplaces, or technology companies with sophisticated digital experiences.

• Ability to critically evaluate design decisions and articulate feedback at the level expected from a senior design or UX lead.
• Excellent written communication skills, with the ability to clearly explain why a design does or does not meet professional standards.
• Strong attention to detail and the ability to apply consistent evaluation criteria across different design solutions.
• Comfortable receiving feedback and having professional judgment reviewed and calibrated against other experts.
