As a Senior Product Designer on the Product Design team, you'll independently lead complex design projects across the end-to-end buyer and seller experience on iOS, Android and web, shaping the look, feel and functionality of a marketplace used by millions. You'll partner with product management, engineering, research and marketing to turn user insight and data into designs that move business KPIs. It's a chance to own hard two-sided marketplace problems from first research through launch and iteration, while raising the craft bar for the team.
