UX/UI Product Designer (UK-Based) — AI Training

About the Project

Mercor is recruiting UK-based UX/UI Product Designers with technical web engineering experience for a research project with a leading frontier AI lab. We're seeking experienced UX/UI designers who have worked on end-to-end digital product design and have a strong understanding of how modern web products are built. Candidates should be comfortable working across user experience, interface design, product flows, technical constraints, and design-to-engineering handoff.

This role is focused on digital product design, not brand identity or marketing-site-only design. Strong candidates have experience designing functional web products such as e-commerce platforms, marketplaces, customer portals, booking flows, onboarding journeys, checkout experiences, or internal operations dashboards.

• UX/UI design for complex web products
• E-commerce or marketplace user flows
• Checkout, booking, onboarding, or account management experiences
• Logged-in customer portals and self-serve platforms
• Internal tools, admin panels, or operations dashboards
• Product design systems and component-based design
• Design-to-engineering handoff and implementation collaboration
• Working closely with product managers, engineers, and data/analytics teams
• Understanding of front-end engineering constraints, responsive design, and web implementation tradeoffs

Preferred Firms (one or more of)

Publicis Sapient, Red Badger, Valtech, Kin + Carta, ustwo, EPAM Continuum (Experience Design / Product Design roles), or another leading digital product, UX/UI, or product engineering studio.

Requirements
