Data Annotation is seeking an experienced UI/UX Product Designer to evaluate how frontier AI models perform on realistic visual design tasks.

• Create challenging, realistic design briefs using your own professional expertise.
• Run briefs through frontier AI design tools and evaluate the output to the level you would expect from a colleague.
• Compare two model versions using identical prompts and assets, then determine which performed better and document where each fell short.
• Critique model-generated materials including interfaces, mockups, layouts, slides, infographics, illustrations, and motion.
• Identify concrete failures with evidence, including alignment and spacing, content overflow and cutoff, typography, visual hierarchy, SVG and illustration quality, ignored assets, and off-brief interpretation.

• Fluency in English at a native or bilingual level.
• Background in UI/UX design, web design, product design, or graphic design.
