Job description

Ready to change the way organisations work with sensitive data? Roseman Labs has built the platform for secure information sharing networks, so organisations learn new insights from each other’s data without revealing their own. Major European banks already use it to fight financial crime, while law enforcement and defence organisations use it to protectnational security. Our work with public and healthcare organisations led us to jointly receive the Dutch Privacy Award for the third consecutive time in 2026.

We’re a team of 35 people from 6 nationalities, with backgrounds ranging from cryptography and engineering to sales, customer success and operations. We work from our office in Utrecht, and we’re curious, ambitious, and enjoy working together.As a young and fast-growing company, we’re getting ready for our next phase of international growth.

About the role

In this role you work directly with our Head of Operations and other members of the company leadership to keep the business running smoothly. As part of our team, you help bring people together in our office space and ensure people enjoy coming in. You take initiative to maintain and improve the office as a welcoming space for the team and external visitors.

• Run the office and bring the team together. You’ll look after the office and bring people together with team-wide events and social activities. You get people involved and make it easy for them to pitch in. You are a facilitator as much as a do-er; encouraging initiatives with a pragmatic can-do mentality.

• Management support. You’ll support management and shareholder meetings, calendars and travel arrangements. You often interface directly with external stakeholders and handle competing priorities with professionalism and efficiency.

• Shape the role together. It’s a broad role with room to grow in the direction that suits you. We’ll work that out together.

• €3,100–€4,800 gross per month based on 40 hours, pro rata for 25-40 hours (depending on experience)

• 3+ years of experience as Executive Assistant, Office Manager or similar

• Confident with Microsoft 365 and fast learning new tools

• You handle confidential information with discretion
