Catawiki

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.

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. STRATEGY & INSIGHT-DRIVEN EXECUTION * Use data-driven insights to identify opportunities to improve seller success, expert workflows, and overall commercial impact. * Engage and align key stakeholders across Sales, Category Management, and Product to ensure buy-in and shared accountability for program success.
