The work spans both Product Design and AI-assisted development (Vibecoding), focusing on how experienced product builders solve complex design, usability, and product development challenges.

  • Apply human-centered design principles and product-thinking methodologies to assess work quality.
  • Evaluate AI-generated and human-created design deliverables for usability, functionality, and execution quality.
  • Author detailed rubrics that distinguish senior-level product judgment from basic or template-driven work.
  • Collaborate with project teams to improve AI performance across design and product development workflows.

Preferred Qualifications

  • Direct ownership of design systems, product experiences, or AI-assisted development workflows shipped to production.
