Senior Product Designer (d/f/m)

About the role

As a Senior Product Designer in our Core domain, you will shape the end-to-end experience that enables millions of users to buy and sell successfully.
You’ll own design across the entire product lifecycle: From early discovery and problem framing to concept development, prototyping, delivery, and continuous iteration.

Working closely with product managers, engineers, researchers, and data specialists, you’ll help build intuitive, reliable, and delightful experiences that empower users to sell with confidence, find what they need and interact safely on the platform.

As part of the broader Product Design team, you’ll regularly exchange ideas, participate in design reviews, and help build a strong, collaborative design culture across the organisation.
