• Solid UX fundamentals: information architecture, interaction design, usability heuristics, and user flows.
• Hands-on experience designing UX for AI agentic workflows and using AI tools (e.g., Claude, Figma Make) as part of the design process.
• Experience contributing to and designing within a design system.
• Proven ability to move from ambiguous problems to working prototypes and to partner with engineering/product to ship features.
• Strong communication skills and ability to defend design decisions.
