The posting

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

As a Minerals Expert within the Natural History & Finds category, part of the Collectables Supercluster, you will strengthen the quality and commercial performance of our Minerals auctions. You will use your specialist knowledge to curate authentic, attractive specimens, deliver a transparent auction experience, and drive buyer engagement.

You will also help grow and diversify our global seller base, identify new commercial opportunities, and contribute to category-wide initiatives that support long-term growth.

What You’ll Do

  • Curate high-quality Minerals auctions by evaluating specimens for authenticity, rarity, quality, and commercial appeal, ensuring accurate descriptions, strong photography, and realistic estimates.
  • Drive commercial performance through informed curation decisions, competitive pricing, and the identification of valuable specimens and emerging market opportunities.
  • Expand and diversify our seller base by partnering with Sales and Business Development to recruit new sellers, reactivate inactive sellers, and develop supply across new regions.
  • Leverage your industry network to build relationships with miners, dealers, collectors, and specialist suppliers, unlocking new sources of supply and commercial opportunities.
  • Lead category initiatives including special auctions, targeted seller activations, supply expansion projects, and cross-category opportunities within Natural History & Finds.
  • Shape category strategy by using market insights, auction data, and specialist knowledge to identify growth opportunities and improve curation standards and processes.
  • Collaborate across teams to support auction visibility, attract bidders, share expertise, and maintain professional relationships with sellers and internal stakeholders.

What You’ll Bring

  • Deep expertise in Minerals, including mineralogy, geological contexts, specimen quality, rarity, authenticity, pricing, and market values.
  • At least 5 years of professional experience in the Minerals trade, whether as a dealer, curator, collector, academic specialist, or commercial expert.
  • An established industry network of Mineral dealers, miners, collectors, and specialist suppliers, with the ability to identify and develop new sources of supply.
  • Strong commercial judgement, with experience in seller engagement, deal-making, auctions, or marketplaces, alongside an understanding of online buyer behaviour and curation best practices.
  • An independent, proactive approach, with the ability to lead projects, identify opportunities, and contribute to shared category goals.
  • Strong communication and collaboration skills, including the ability to work across teams, build professional relationships, and resolve disputes constructively.
  • Good digital literacy and fluency in English, with the ability to work in a fast-paced online environment. Additional languages and knowledge of Fossils, Meteorites, or other Natural History fields are an advantage.

How We Work

  • Work remotely as part of the Natural History & Finds category within the wider Collectables Supercluster.
  • Collaborate closely with fellow Experts, Account Managers, Business Development, Marketing, and the Category Lead to achieve shared commercial and category goals.
  • Take ownership of projects and initiatives while contributing to improvements in team processes, curation standards, and ways of working.
  • Share specialist knowledge and market insights across Minerals, Fossils, Meteorites, and Archaeological Finds to support cross-category opportunities.

Where You’ll Be

This is a 100% remote role based in one of our European locations: Belgium, France, Germany, Italy, the Netherlands, Portugal, Spain, or the United Kingdom.

Why You'll Love Working with Us

  • Create a visible impact by working at scale in a global organisation serving millions of customers across 80+ categories. In our flat structure, every role has a broad scope and directly impacts both our customers and the business.
  • Learn and grow through our Learning & Development initiatives, including clear development plans and mentorship programmes to support your career progression.
  • A culture of connection defines us. We’re a passionate, diverse team of 800+ Catawikians representing 60+ nationalities. We foster an inclusive and queer-friendly environment where everyone is encouraged to bring their full self to work.
  • Celebrate life’s moments with us. You’ll receive a €100 Catavoucher when you join, a €50 Catavoucher on your birthday, and an extra day off each year to “Pursue Your Passion”. We also offer additional leave for key work anniversaries and important life events. Benefits may vary by location.

Our Offices and Way of Working

Our vibrant offices in Amsterdam and Lisbon are designed to inspire collaboration. Most Catawikians operate in a hybrid setup, combining office-based and remote work, with a minimum of two days per week in the office, unless a role is explicitly stated as fully remote or fully office-based.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
