Product/UX Professionals - AI Training - London, UK

Prolific is not just another player in the AI space – we are building the biggest pool of quality human data in the world. Over 35,000 AI developers, researchers, and organizations use Prolific to gather data from paid study participants with a wide variety of experiences, knowledge, and skills.

We’re looking for Product Designers and UX Specialists to join our Expert Network to help train and evaluate cutting‑edge AI models using real design expertise. If you have the necessary experience, we’ll send you a quick 10‑ to 15‑minute test to assess your skills and suitability for AI tasks. If successful, you’ll be invited to join Prolific as a participant, where you’ll get paid to train and evaluate powerful AI models. Researchers looking for your skills tend to pay up to $50 per hour. You must be prepared to complete paid tasks that require one hour of uninterrupted work, though many are shorter.

What you’ll bring

• Education: A BS, MS, or PhD in Human-Computer Interaction (HCI), UX Design, Product Design, or a related field.
• Professional Experience: at least one year of experience designing digital products, conducting user research, or building design systems in a professional environment.
• Design Intuition: a deep understanding of usability heuristics, accessibility standards (WCAG), and user-centered design principles.
• Analytical Critique: the ability to provide high-quality feedback on UI layouts, user flows, and information architecture.
• Strategic Thinking: experience balancing user needs with business goals and technical constraints.
• Communication: proficiency in explaining the "why" behind design decisions and critiquing AI-generated designs for functional and aesthetic quality.
• A PayPal account to receive payment from our clients.

What you’ll be doing in the role

• Evaluate LLM-Generated Designs: assess AI-generated wireframes, user flows, and product requirements for usability and logical consistency.
• Audit Accessibility & Inclusion: review model outputs to ensure they adhere to modern accessibility standards and inclusive design practices.
• Fact-Check UX Principles: validate that model suggestions align with established design patterns and psychological principles (e.g., Fitts's Law, Gestalt principles).
• Annotate Design Logic: identify gaps in user journeys, redundant steps in a flow, or poor visual hierarchy in AI-proposed interfaces.
• Refine Product Requirements: evaluate AI-generated PRDs (Product Requirement Documents) for clarity, feasibility, and user value.

Key Technologies

• Design Tools: advanced knowledge of Figma, Adobe Creative Suite, or Sketch.
• Prototyping: experience with high-fidelity prototyping tools (Protopie, Framer) and handoff processes.
• User Research: familiarity with tools like Maze, UserTesting, or Hotjar to validate design hypotheses.
