- Portfolio demonstrating: (1) very high-level visual design craft with attention to detail; (2) history of shipping consumer-facing features, ideally 0-1 products or early-stage startup experience; (3) track record of making informed design decisions with measurable product impact
- Ability to make appropriate tradeoffs between short-term and long-term goals informed by business and user needs
- Strong interaction, visual, and design system skills: expert-level Figma proficiency and fluency with prototyping tools
