Who we're looking for:

•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)
