We're looking for a proactive, detail-oriented Office Assistant to join our People team in Amsterdam. This is a fully on-site, part-time role (24h/week). If you can join us mid-May or June, it would be great!

You'll be the heartbeat of our office — making sure everything runs smoothly and that every person who walks through our door feels genuinely welcome. Working closely with our Office Manager & Relocation Coordinator, you'll help build the kind of workplace people are excited to come back to.

This role is a great fit if you love being hands-on, thrive in a fast-moving environment, and find real satisfaction in keeping things organized and people well looked after. No two days will be identical, and that's exactly the point.

What you will do

• Keep the office running — daily rounds to make sure the space is tidy, functional, and well-stocked

• Welcome visitors — be the first face people see, and make sure that first impression counts

• Plan and run events — coordinate internal events and team moments that bring people together

• Office upkeep — liaise with vendors and building management on repairs, maintenance, and improvements

• Manage supplies — monitor stock levels and place orders before things run out

• Handle correspondence — manage incoming and outgoing office mail and deliveries

• Vendor relationships — build and maintain relationships with service providers, suppliers, and our landlord

• Support internal comms — help coordinate company-wide logistics and communications

• Collaborate cross-team — work with colleagues across the business on office and people initiatives

About you

• You're proactive — you notice what needs doing before being asked

• You're a natural organiser who takes pride in the details

• You communicate clearly and warmly with people at all levels

• You're comfortable managing several things at once without dropping the ball

• You speak English fluently; Dutch is a plus

• Previous experience in an office coordination, hospitality, or operations role is a plus — but enthusiasm and the right attitude matter most

• Be on the front line of progress and innovation. While working with cutting-edge technology, we are passionate about tackling difficult tech problems at scale and creating reusable components for them, empowering engineering teams to ship apps faster, more securely, and with a better user experience.
