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.
The Role:
Nebius is growing quickly in Asia Pacific and Japan, and our Singapore office is the regional base for our go-to-market team. We are looking for a senior Executive Assistant and Office Manager who will be the right hand to the APJ General Manager, the operational backbone of the Singapore office, and a trusted partner to the Sales and GTM teams on the ground.
This is a hybrid role with three equal pillars: high-level executive support, hands-on office and workplace management, and day-to-day commercial support for the in-region sales and GTM organisation. You will free the GM to focus on growing the business, help the sales team move faster, and make sure colleagues and visitors experience a well-run, welcoming workplace.
Responsibilities:
Executive support to the APJ General Manager
Manage the GM's calendar, prioritising meetings across APJ, EMEA and US time zones.
Coordinate complex regional and international travel, including itineraries, visas, expenses and logistics.

Support the GM's leadership meetings, offsites, customer events and regional business reviews.
Handle expense reports, invoices and other administrative tasks for the GM.
Handle confidential information with the highest level of discretion.
Sales and GTM team support
Act as the first point of contact for the Singapore-based Sales, Partnerships and GTM teams, coordinating requests for information and support.
Support CRM hygiene (Salesforce/HubSpot): data entry, report generation and pipeline tracking, in partnership with Sales Operations.
Coordinate the preparation of proposals, contracts and client-facing materials, and liaise with Finance, Legal and Operations on order processing and accuracy.
Assist with weekly and monthly sales performance reports, dashboards and KPI tracking, and help prepare leadership presentations.
Organise customer meetings, executive briefings, workshops and on-site visits, including room, catering, hospitality and visitor logistics.
Plan and run team events, offsites, kick-offs and regional GTM gatherings.
Support onboarding of new sales and GTM hires, including desk, access, equipment, system access, training schedules and materials.
Manage team communication channels (email, Slack) for announcements and updates, and provide ad-hoc support for strategic initiatives.
Office management and operations
Oversee the day-to-day operations of the Singapore office.
Manage relationships with landlords, building management and service providers, holding them to agreed service levels.
Coordinate maintenance and facilities issues, and escalate and resolve them promptly.

Support seating plans, space usage and small-scale office improvements as the team grows, including future expansion or relocation planning.
Safety, security and compliance
Maintain a safe, secure and compliant office, including emergency procedures, fire safety, first aid and evacuation drills.
Coordinate with building management on security and access control.
Support business continuity and incident response for the Singapore office.
Keep records and documentation in line with local regulations (including MOM requirements) and Nebius policies.
Employee experience
Create a welcoming environment for colleagues and visitors, from arrival to day-to-day service.
Host visits from global colleagues and coordinate their travel and workplace needs.
Partner with HR and IT on new joiner readiness.
Collect feedback and suggest improvements to the workplace experience.
Budget, vendors and reporting
Manage the Singapore office budget, including purchase orders, invoice processing, cost tracking and forecasting support.
Work with Finance and Procurement on vendor onboarding, contracts and renewals.

Communicate proactively about office changes, disruptions and events.
