Senior Product Designers, UX/UI & AI-Assisted Development Experts.
We are seeking experienced product designers, UX/UI designers, design system specialists, AI-assisted developers, rapid prototypers, and AI-native product builders to create realistic evaluation tasks for advanced AI systems.
This opportunity spans two tracks: AI-assisted development / Vibecoding and Product Design / UX/UI. Professionals with deep expertise in either track, or experience across both, are encouraged to apply.
What You’ll Do
Create realistic product design and rapid-prototyping scenarios
Develop tasks involving AI-assisted coding, natural-language-to-code workflows, UX/UI design, design systems, user research, and usability testing
Build reference prototypes, code artifacts, design specifications, component systems, and usability evaluations
Design scenarios involving cross-functional collaboration between product, engineering, design, and research teams
Evaluate whether outputs demonstrate genuine senior-level product judgment
Create scoring rubrics that distinguish strong professional work from generic templates or tutorial-level solutions
Apply iterative prototyping, human-centered design, heuristic evaluation, and AI-assisted development methodologies
