Senior UX Designer - Seller Experience

Your mission

Every designer at Catawiki shapes a meaningful part of the customer experience.

In Seller Experience, your mission is to make it easier for sellers to bring special objects to Catawiki and for our experts to select and curate them. You will improve the experiences and tools that help sellers get started, submit objects and work with our experts.The seller journey is closely connected to the quality of the objects buyers discover on Catawiki. You will work across that journey to understand where people need support, identify the most valuable design opportunities and create experiences that work for customers, the business and the technology behind them.

You will partner closely with Product, Engineering, Data and other designers. From research and early concepts through prototyping, delivery and learning after launch, you will help the team turn complex problems into clear, useful experiences.

1. Lead design for important parts of the seller and expert experience, from early discovery through launch and improvement.
2. Use customer research, behavioural data and business insight to identify needs and design opportunities.
3. Turn ambiguous customer problems into clear journeys, concepts, prototypes and design plans.
4. Explore and test ideas with customers and colleagues, using what you learn to improve the experience.
5. Create thoughtful interaction and interface designs, prototypes and service flows that make complex tasks clear and intuitive.
6. Partner with Product Managers, Engineers, Data Scientists, UX Writers and other designers to shape and deliver solutions.
7. Connect customer needs with business goals and technical constraints, helping the team make sound tradeoffs.
8. Contribute to design systems and shared patterns that create coherent experiences across Catawiki.
9. Share your design rationale, bring feedback into the process and help stakeholders reach clear decisions.
10. Use AI and rapid prototyping tools to explore ideas and test assumptions when they help solve a meaningful customer problem.
