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 110,000 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.

What You Will Do

As a Category Marketing Sr Specialist, you’ll be the strategic driver behind ensuring the business unit meets its marketing objectives. From campaign strategy to execution, you will shape how we connect with our customers and help us realize our ambition of becoming the world’s most popular destination for special objects.

• Leverage Data for Impact: Monitor and analyze category performance metrics (e.g., RGMV, ALV, RP sell rate). Translate insights into clear actions that fuel performance and category growth.

• Lead the Marketing Calendar: Own and maintain the Supercluster marketing calendar, ensuring it aligns with commercial priorities and consumer trends.

• Campaign Strategy & Execution: Partner with the Category Marketing Lead to co-develop, launch, and evaluate high-impact campaigns. Be proactive in testing new approaches and continuously optimizing performance.

• Shape Merchandising Strategy: Use data to forecast demand trends and align supply accordingly. Collaborate closely with category teams to influence sourcing and inventory decisions.

• Run Strategic Initiatives: Independently manage smaller-scale marketing and growth projects that support overarching cluster and company goals.

Who You Are

• Independent: You think big, act autonomously, and thrive on taking initiative.

• Data-Driven: You know how to extract actionable insights from performance metrics and dashboards.

• Strong Collaborator: You bring people together, communicate effectively, and align stakeholders behind shared goals.

• Marketing Foundations: You bring 3–5 years of experience in digital marketing, ideally in a fast-paced, high-growth environment. Ambitious recent graduates with relevant backgrounds are also encouraged to apply.

• Growth-Minded: You’re eager to learn, adapt quickly, and excited by the opportunity to scale your impact as we grow.

This role is based in Amsterdam, the Netherlands, with flexibility under our hybrid working model.
