  • A portfolio demonstrating exceptional visual design craft and interaction design — with shipped products, not just concepts
  • Demonstrated use of AI-native design and prototyping workflows: you actively use agentic coding tools (e.g., Cursor, GitHub Copilot, v0, Bolt, or similar) to produce working UI, not just static mockups
  • Ability to write or direct frontend code (HTML/CSS/JavaScript/React or equivalent) using AI coding assistants — you don't need to be a software engineer, but you can ship production-quality UI with AI tools
  • Strong foundations in graphic design: typography, layout, color theory, and visual hierarchy

  • Prototype at speed: Rapidly produce interactive, high-fidelity prototypes to test new interaction paradigms for multimodal, agentic, and copilot-style AI experiences. Use AI tools to compress iteration cycles from days to hours
  • Elevate visual craft and interaction quality: Apply strong graphic design foundations — typography, layout, color, motion — to create experiences that feel polished, intentional, and trustworthy. Sweat the details that make AI feel human
  • Partner with model designers and researchers: Collaborate closely with model designers (who shape how the AI speaks and behaves) and researchers (who build the underlying capabilities) to ensure the UX faithfully represents model personality and strengths
  • Inform design systems: Contribute to and extend shared design systems, component libraries, and interaction patterns — ensuring consistency across surfaces while pushing the craft forward
  • Drive design through data and user insight: Use both qualitative and quantitative signals (user research, analytics, A/B experiments) to validate design decisions and iterate. Bring evidence, not just intuition
  • Automate your own workflow: Continuously explore and adopt new AI tools, plugins, and workflows that make you faster and more capable. Share what you learn with the team.
