Product Designer | $75/hr | Remote

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

• Experience building and shipping products using AI coding assistants
• Experience owning large-scale design systems or component libraries
• Experience moving rapidly from concept to functional prototype
• Strong understanding of both UX principles and technical implementation
• Experience reviewing or critiquing the work of designers or engineers
• Experience creating product design standards, training materials, design critiques, or evaluation frameworks
• Prior work involving AI evaluation, benchmark creation, human feedback, or structured quality assessment

A formal credential is not required. A strong portfolio of shipped work, real product ownership, and demonstrated senior-level judgment are highly valued.

This opportunity is ideal for experienced product builders who understand both the craft of creating excellent user experiences and the rapidly evolving workflows of AI-assisted product development. We are a referral partner of the client.
