Onodrim is building Europe's largest defence and industrial platform. We acquire specialist manufacturers in critical defence and dual-use supply chains. Then we invest in their growth with capital, technology and operating know-how.

Europe is rearming, and its industrial base has to keep pace. Many of the companies that make the parts, systems and materials Europe's defence depends on are small, specialised and short of capital. We want to help them scale into global champions, so that Europe and its allies can produce what they need, at the speed they need it.

The Executive Assistant gives Onodrim's executives the time and focus to run a fast-growing company. You'll manage their calendars, travel, meetings, and make sure nothing falls through the cracks between them.

The role is based in Amsterdam, our headquarters. The rest of the team works from other European cities, so much of your work will span locations and time zones.

What you'll do:

Manage executive calendars. Own complex, changing schedules across time zones, and protect time for what matters most.
Coordinate travel. Plan and book multi-city trips across Europe and beyond, including itineraries, logistics and last-minute changes.
Follow up on meetings. Track actions agreed in internal and external meetings and make sure they are completed.
Support event organization. Support in organizing off-sites, travel and conference attendance.
Prepare presentations and documents. Produce clean, well-formatted slides, memos and reports.
Handle ad-hoc requests. Pick up whatever else the executives need as it comes up. Act as a trusted partner to the executive you will support.

Requirements

At least 4 years' experience as an Executive Assistant supporting senior leaders, ideally in a fast-paced or international environment such as private equity, investment, consulting or a scale-up.
Experience managing calendars, travel and correspondence.
Strong organisation and attention to detail, and the ability to keep many priorities moving without dropping any.
Sound judgement about what to escalate, what to handle yourself and how to represent the executives you support.
A proactive, independent way of working: you anticipate needs, take ownership and don't need close supervision.
Motivation that comes from the mission and the impact of the work, not from a title or hierarchy.
A strong sense of follow-through. You finish what you start and hold yourself to a high standard.
An international mindset, and experience working across different cultures, countries and time zones.
Complete discretion. You'll regularly handle confidential information about transactions, stakeholders and people.
A real interest in European defence and security, and comfort working in the defence sector. You don't need to be an expert, but you should care about what we are building and why it matters for Europe.
Fluent written and spoken English.
Confidence with Google Workspace, Slack and similar tools, and the ability to produce clean, well-formatted slides.
Flexibility in an early-stage company: hours and priorities sometimes shift, and you're comfortable with that.
Willingness to travel occasionally.

Nice to have:

We work in English, but fluency in one or more other European languages is very helpful and a plus.
Experience in a startup or scale-up.
Exposure to the defence, security, government or investment sectors.
Clearance in at least one of our operating countries.
