[Hiring] UX-UI Designer Expert @Sojistudio

Role Description

Mercor is partnering with a leading AI research organization to engage experienced UI/UX and product designers for a project focused on evaluating how well AI systems perform real-world digital product design work. Rather than producing deliverables yourself, you will define what excellent work looks like:

• Designing task-specific grading criteria
• Scoring completed work samples with rigorous, well-reasoned written justifications

Key Responsibilities

• Design precise, task-specific grading criteria for real-world digital product and UX deliverables, including:
  • Design systems and component libraries
  • Responsive UI layouts and dashboards
  • End-to-end product flows such as onboarding, checkout, and booking
  • Logged-in customer portals
  • UX writing and product content
  • Design-to-engineering/production handoff
• Score AI-generated and human work samples against those criteria, with detailed written justifications for every score
• Apply consistent, evidence-based judgment so that scores are reproducible and defensible
• Incorporate structured feedback from senior reviewers and iterate quickly on your work

Qualifications

• 5+ years of professional experience in product design, UI/UX, or design systems for real digital products (not brand or marketing sites)
• Background at leading digital-product and UX studios, in-house product-design teams at major product-led companies, or e-commerce and marketplace companies with sophisticated customer portals and dashboards
• Experience across one or more relevant tracks: Product / UI / Design Systems Designer, UX Lead, UX Writer / Content Designer, or digital Product / Business Analyst
• Deep fluency in the day-to-day craft: interaction and visual design, design systems, responsive layouts, end-to-end product flows, prototyping and production handoff in Figma, and articulating critique the way a design or UX lead would in a review
• Exceptionally strong written communication, with the ability to explain exactly why a piece of work does or does not meet the bar for a real product and its users
• Detail-oriented, consistent, and comfortable having your judgment reviewed and calibrated against peers
• Prior experience with AI training, evaluation, or human-data projects is a strong plus

Application Process

• Submit your resume, portfolio, or relevant professional background to get started
• Qualified applicants may be asked to complete a brief assessment or submit additional information

Restrictions

• We are unable to support H1-B or STEM OPT candidates at this time.
