At Catawiki, every day brings the extraordinary! Whether it’s Daniel Ricciardo’s Formula 1 Car, a Woolly Mammoth’s Skeleton, Lady Gaga's Jumpsuit or Usain Bolt’s running shoe, we encounter exceptional objects every day. We’re a one-of-a-kind marketplace for buying and selling special objects. Each week, more than 100,000 unique items are auctioned, all carefully curated by our passionate in-house experts. Having sold over 25 million unique objects, our mission is to become the world’s most popular destination for special objects. As a growing, diverse and sustainable scale-up, we proudly live by three core values. If these values resonate with you, we’d love to explore how you can join us. * Taking ownership and driving impact  * Being open to change and feedback * Being passionate about our mission and our customers.  YOUR MISSION Catawiki is on a journey to scale its Commercial organisation to support our mission: connecting passionate enthusiasts with exceptional objects. To further unlock this growth, we are expanding the function that empowers our Sellers, Sales and Expert teams with the strategy, tools, and insights they need to thrive. As a Junior Project Manager in Supply Operations, you will help drive the execution of cross-functional initiatives that improve how we attract, engage, and retain high-potential sellers. You will work closely with Sales, Category Management, Product, and other operational stakeholders to coordinate priorities, support rollouts, and turn strategic plans into scalable workflows and day-to-day execution. This role will support a broad range of initiatives across commercial enablement and seller excellence, from product GTMs to operational improvements in our CRM system, and curation tooling.

Expert operations: enabling our domain experts to scout, assess, and optimise supply through support, tooling, and data, from object intake to auction placement. Seller excellence: defining what “good” looks like for our sellers and shaping behaviour through programs that blend education, accountability, and incentives. We partner with Product, Marketing, Trust & Safety, and Data Science to deliver initiatives such as seller education, loyalty programs, affiliate supply, and product co-design. Our team is made up of project and program managers, led by a Manager reporting into the VP of Commercial Operations. We operate cross-functionally, building bridges between Commercial and Tech to design scalable, high-impact solutions.
