Paid Digital Marketing Intern

Every year, billions of clothing items are produced but never sold. Much of this unworn fashion ends up in landfills – a massive waste of creativity, craftsmanship, resources, and investment. We're here to change that. As a purpose-led company, we use technology to help fashion brands give every item a chance to be worn. And we’re proud to be a certified B Corp – recognised for meeting high standards of social and environmental impact, transparency, and accountability.

We’re a purpose-driven scale-up, based in Amsterdam and active across Europe, with a diverse and international team. Our mission is simple: sell unsold inventory. Otrium values a healthy work-life balance. We have adopted a flexible hybrid way of working, encouraging our team members to come to our open, spacious, plant-filled Amsterdam HQ at the waterside of Houthavens at least twice a week. Full-time office presence is welcomed, and you’re empowered to organise your schedule in a way that works for you and the team.
