• Exceptional design craft: interaction detail, hierarchy, typography and motion

• High autonomy: you take ownership without needing much structure

• Experience with design systems and shipping features end-to-end

• Product and analytics thinking: you don't design from your gut, you measure

• AI-first mindset

• Fluent English (any additional language is a plus, especially German (DACH is our most important market)
