Client out wireframes with the right widget classes so visual designers can start styling

Rapidly prototype UX/Visual designs; translate design needs into technical requirements for programmers

Ensure player input is correctly mapped, responsive, and has appropriate "game feel"

Proven experience designing and implementing navigation flows and screen-to-screen relationships in a live product

Ability to work from a component/template library and assemble it into cohesive, production-quality experiences

Strong problem-solving skills, particularly around complex, context-dependent navigation and state (e.g., scoped or contextual UI systems)

Solid understanding of UI performance considerations in real-time engines

Excellent collaboration skills, with the ability to work closely across art, UX, and engineering disciplines
