About the Opportunity

This opportunity is for experienced Product Design, UX/UI, and AI-Assisted Development professionals interested in contributing to advanced AI research and evaluation projects involving rapid prototyping, product design, and human-AI collaborative development workflows.

The role focuses on creating realistic design and development scenarios, developing reference solutions, and building evaluation criteria that reflect how senior designers, product builders, and AI-native developers operate in modern product organizations.

You'll apply your expertise in product design, design systems, user experience, rapid prototyping, and AI-assisted development to help improve the capabilities of next-generation AI systems.

Key Responsibilities

  • Design realistic scenarios involving rapid prototyping, product development, and cross-functional product-design-engineering collaboration.
  • Develop tasks covering UX/UI design, design systems, component libraries, user research, usability testing, and visual design workflows.
  • Create AI-assisted development and vibecoding tasks involving natural-language-to-code workflows, rapid application development, and prototype creation.
  • Utilize tools such as Figma, Framer, Cursor, Claude Code, v0, Replit, and other modern design and development platforms.
  • Apply human-centered design principles, heuristic evaluation methods, design thinking frameworks, and iterative AI-assisted development methodologies.
  • Create reference prototypes, design specifications, usability reports, and development artifacts.
  • Develop evaluation rubrics that distinguish authentic senior-level design and product judgment from generic or template-driven work.
  • Evaluate outputs based on user experience quality, design thinking, technical feasibility, product impact, and execution excellence.

Required Qualifications

  • 5+ years of experience as a Product Designer, UX/UI Designer, Design Lead, AI-Native Builder, or similar professional role.
  • Experience working at leading product, technology, startup, or design-focused organizations.
  • Direct ownership of design systems, product experiences, AI-assisted development workflows, or production-ready digital products.
  • Strong expertise in product design, user experience, design systems, rapid prototyping, and collaborative product development.
  • Fluency with modern design and development tools, including Figma, Framer, Cursor, Claude Code, v0, Replit, or equivalent platforms.
  • Strong understanding of user-centered design principles and product development best practices.
  • Excellent written and verbal communication skills.

Preferred Qualifications

  • Portfolio demonstrating shipped products, design systems, or AI-assisted development projects.
  • Experience creating design frameworks, evaluation rubrics, training materials, or design documentation.
  • Experience mentoring designers, developers, or product teams.
  • Familiarity with AI product development, AI model evaluation, or AI training workflows.
  • Experience working across multiple product functions and multidisciplinary teams.

Compensation

  • Competitive compensation of $70–$80/hour.
  • Weekly payments.
  • Independent contractor engagement.
