Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.

Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.

We're looking for a proactive, highly organized Team Assistant to support the Head of Infrastructure. In this role, you'll help ensure day-to-day operations run smoothly by providing exceptional executive support and coordinating a wide range of administrative and operational activities. You'll work closely with the Head of Infrastructure and the Executive Support team, handling everything from complex scheduling and travel to team events and operational coordination.

• Coordinate domestic and international travel, including visas, accommodation, transportation, and last-minute itinerary changes.

• Organize meetings from end to end, ensuring all logistics and materials are in place.

• Manage expense reports, reimbursements, and other executive administrative processes.

• Coordinate administrative documentation, including NDAs and other required approvals.

• Coordinate vendors and external partners, including contracts, procurement, invoices, payments, and related administrative processes.

• Drive operational follow-ups by tracking action items and ensuring timely completion of key tasks.

• Continuously improve and document administrative and operational processes.

• Provide backup support to other Team / Executive Assistants and collaborate as part of the Executive Support team.

• Take ownership of ad hoc operational projects and administrative initiatives that help the organization run efficiently.

What we're looking for:

• Experience supporting senior executives in a fast-paced, dynamic environment.

• Exceptional organizational skills with outstanding attention to detail and accuracy.

• Flexibility to adapt to changing priorities and, when needed, adjust working hours to support executive schedules.

• A willingness to go the extra mile to find the best solution, not just the first one.

• A proactive, service-oriented mindset—you anticipate needs, identify potential issues early, and take pride in delivering high-quality support.

• Strong communication skills, professionalism, and discretion when handling confidential information.

• A collaborative, positive attitude—you build strong relationships and are easy to work with across teams and with external partners.

• Someone who genuinely enjoys executive support as a long-term career and takes pride in enabling others to succeed.
