Merchandiser

Our purpose

Otrium is a purpose-led business – we see a future where all clothing is worn.

Every year, billions of items are produced globally but are never sold. Clothing goes unworn and often ends up in landfills. This is a huge waste of creative energy, labour, natural resources and investment. Otrium is changing fashion from the inside out: we are an online fashion outlet marketplace and we tech-enable designer brands to find an owner for every item they produce.

How we work

Founded and headquartered in Amsterdam, operating across Europe, Otrium is a start-up company whose diverse, talented and international team, works diligently and passionately to achieve one mission: Wear Over Waste. We have a hybrid set-up which offers flexibility and freedom to our O-Team - this means we encourage our (local) O-Team members to join together in our office based in the Houthavens, Amsterdam at least 2 days per week.

We are looking for a highly commercial and data-driven E-Commerce Merchandiser to join our growing Partnerships team within a fast-paced multi-brand, multi-category fashion marketplace. This role is ideal for someone with demonstrated experience in e-commerce merchandising and trading who is confident using data and customer insights to drive commercial decisions and performance.

Sitting at the intersection of supply, trading, and onsite merchandising, this role will support product selection across partner brands to ensure the right products are available at the right price and at the right time.

The role will support in-season trading decisions, campaign planning, and onsite product merchandising, while helping drive commercial performance through effective stock management, sell-through optimisation, and end-of-lifecycle trading actions. Using trading insights, inventory availability, and key merchandising KPIs, the E-commerce Merchandiser will help optimise inventory productivity and customer conversion, while contributing to wider commercial and operational projects across the department.
