  • Thoughtful storytelling and range

  • High‑quality execution and attention to detail

• Strong foundation in typography, layout, color, and composition.

• Experience designing for digital surfaces such as web or product interfaces.

• Startup or fast‑paced team experience.

• Motion, illustration, or 3D skills.

• Familiarity with or curiosity about web3 products and ecosystems.

• Experience collaborating on product UI or product‑adjacent design work.

• Defining the visual direction for a new initiative or early‑stage product.
