About this role

From the Mercor listing

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 are 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 should have experience designing functional web products such as e-commerce platforms, marketplaces, customer portals, booking flows, onboarding journeys, checkout experiences, or internal operations dashboards.

Ideal candidates have experience with one or more of the following:

  • 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 front-end engineering constraints, responsive design, and web implementation tradeoffs

Preferred candidates have experience at one or more of the following companies:

  • Publicis Sapient

  • Red Badger

  • Valtech

  • Kin + Carta

  • ustwo

  • EPAM Continuum, specifically Experience Design / Product Design roles

  • Or another leading digital product, UX/UI, or product engineering studio

You'll help create, review, and evaluate high-quality UX/UI product scenarios, leveraging your experience in product design, web interfaces, user flows, and design-engineering collaboration.

The vetting process involves:

  • Resume and portfolio review

  • Short interview evaluating UX/UI product design and web product expertise

Please note: Candidates must be based in the United Kingdom and have the right to work in the United Kingdom. These are essential requirements for the role.

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.

Requirements

  • Must be eligible to work in one of: Remote, United Kingdom
  • Fluent proficiency in English (Written & Verbal)
  • Reliable high-speed internet connection
  • Master's's degree or equivalent professional experience

Common questions

Is Mercor for freelancers or full-time contractors?

Mercor places you with one client for a defined engagement, like 'Python Tutor for 3 months', rather than having you grab small tasks from a shared queue. Most roles function as steady contract work, not one-off gigs.

Does Mercor's application require an on-camera interview?

Yes, every applicant records a video interview with an AI interviewer that asks questions about your resume. Clients review that recording to judge communication skills before matching, so there's no way to apply without going on camera.

Why do these AI training roles pay so much?

Because general knowledge isn't what's being tested. The model already knows the basics; what it needs is expertise on edge cases, the rare, difficult, highly technical judgment calls only a senior professional in the field would make correctly.

What does the day-to-day workload look like for elite-expert AI training roles?

Slow and deep, not fast and repetitive. A single task can take 45-60 minutes of researching citations or verifying complex calculations. Quality is what's being measured here, not throughput.

What does Business work look like for an UK-Based UX/UI Product Designers?

Tasks here are scoped to Business, not generic labeling. As an UK-Based UX/UI Product Designers, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Business) rather than following a one-size-fits-all rubric. If you don't have hands-on Business background, this is likely not the right listing to start with.

What specific skills does this listing call for?

AI Training is named directly in the listing. If you don't have hands-on experience with this, expect the screening process to test for it directly rather than accepting adjacent experience as a substitute.

How much does this specific role pay?

This listing is posted at $150–$200/hr, an hourly rate. The range reflects experience level and negotiated terms, not a placeholder, so where you land in it depends on your background and the assessment. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.

What happens when I click Apply on this listing?

You'll be taken to Mercor's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.

Do I need a Master's to qualify?

This role lists a master's degree as a requirement. In practice, the domain assessment is the real gate. If you can pass it, the degree is usually secondary. However, some platforms verify credentials formally, so list your actual qualifications accurately on your profile.

Can I apply from outside the United Kingdom?

This specific role is open only to people based in the United Kingdom. If you are somewhere else, applying is unlikely to lead to an offer even if you pass the assessment, because the restriction is usually about where the work can legally be contracted rather than your skills. Read the full description for any tax-residency or right-to-work caveats before you apply.

Is there an interview?

Yes. Short interview evaluating UX/UI product design and web product expertise

How soon will I start working after applying to Mercor?

Not immediately. Mercor is a talent marketplace, not a task queue, so applying puts you in a pool of candidates. You start working only once a specific client, like a major AI lab, selects your profile, and that matching process can take weeks.
