About the role and team

We are looking for an experienced Minerals Expert to join the Natural History & Finds category, part of the wider Collectables Supercluster.

Your primary focus will be Mineral specimens, with additional knowledge of Fossils, Meteorites, and Archaeological Finds considered a valuable advantage. You will play a key role in strengthening the category by delivering high-quality curation, driving commercial outcomes, and expanding our global seller base and supply.

This role is ideal for someone who is:

• Commercially strong

• Independent and proactive

• A team player who contributes to shared goals

• Able to lead projects and category initiatives

• Skilled in expanding supply into new regions and network

What you’ll do

Curate high-quality, commercially attractive Minerals auctions

• Evaluate and select Mineral specimens for auction, ensuring accuracy, authenticity, and strong curation.

• Review titles, descriptions, photos, and provide realistic estimates based on market knowledge.

• Maintain high-quality standards and ensure transparency for bidders and sellers.

• Use curation decisions to maximise commercial impact and buyer engagement.

Expand supply & drive commercial growth

• Work closely with Sales and BD to recruit new Mineral sellers, reactivate inactive ones, and diversify supply.

• Leverage your network to access new geographies, miners, dealers, and collectors.

• Identify commercial opportunities such as rare specimens, mine-specific supply, or new subcategories.

• Support high-value initiatives, special auctions, and targeted seller activations.

Lead projects within the Natural History & Finds category

• Take ownership of category-wide initiatives, from supply expansion projects to auction themes.

• Collaborate with colleagues in Fossils, Meteorites, and Finds to create cross-category momentum.

• Use data and market insights to help shape category strategy alongside the Category Lead.

• Support improvements in processes, standards, and team ways of working.

Collaborate across the Collectables Supercluster

• Partner with marketing teams to highlight Minerals auctions and drive bidder traffic.

• Share knowledge with other experts and contribute to a culture of collaboration.

• Communicate professionally and constructively with sellers and internal stakeholders.

What you’ll bring

• Deep expertise in Minerals: mineralogy, specimen quality, geological contexts, rarity, and market values.

• 5+ years of professional experience in the Mineral trade as a dealer, curator, collector, academic specialist, or commercial expert.

• A strong industry network of Mineral dealers, miners, collectors, and specialist suppliers.

• Understanding of auction dynamics and online buyer behaviour.

• Strong teamwork and cross-functional collaboration mindset.

• Demonstrated commercial strength — seller engagement, deal-making, auction or marketplace experience.

• Ability to work independently while contributing to larger category and cluster goals.

• Strong understanding of pricing, value tiers, authenticity requirements, and best practices for online curation.

• Professional communication skills with experience resolving disputes when needed.

• Good computer literacy and comfort working in a fast-paced digital environment.

• Bonus: Knowledge of Fossils, Meteorites, or other Natural History fields.

• English required; additional languages are a plus.

Where you’ll be

This is a fully remote role within the Collectables Supercluster. You will be embedded in the Natural History & Finds category, working closely with Experts, Account Managers, BD, Marketing, and your Category Lead.
