• Apply consistent standards so that evaluations are objective, reproducible, and aligned with real‑world product expectations.
• Incorporate feedback from senior reviewers and continuously refine evaluation approaches.
• Assess designs from the perspective of usability, accessibility, visual quality, interaction patterns, business objectives, and end‑user needs.

3. Ideal Qualifications

• 5+ years of professional experience in product design, UI/UX, UX design, or design systems for real-world digital products.
• Experience working with leading digital-product or UX studios, product‑led organizations, e‑commerce platforms, marketplaces, or technology companies with sophisticated digital experiences.
• Relevant experience in one or more areas such as:
  • Product / UI Designer
  • UX Designer or UX Lead
  • Design Systems Designer
  • UX Writer / Content Designer
  • Digital Product or Business Analyst
• Strong command of interaction design, visual design, responsive layouts, design systems, prototyping, usability principles, and end‑to‑end product flows.
• Hands‑on proficiency with Figma and familiarity with production and engineering handoff processes.
• Ability to critically evaluate design decisions and articulate feedback at the level expected from a senior design or UX lead.
• Excellent written communication skills, with the ability to clearly explain why a design does or does not meet professional standards.
• Strong attention to detail and the ability to apply consistent evaluation criteria across different design solutions.
• Comfortable receiving feedback and having professional judgment reviewed and calibrated against other experts.
• Prior experience with AI training, AI evaluation, or human‑data projects is a plus.

5. Work Arrangement

• Fully remote engagement
• Flexible project‑based schedule
• Work focused on digital product, UI/UX, and design evaluation
• Collaboration with an experienced research and review team

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