About the Role

As an Executive Assistant to 3 of our Directors, you will be the right hand to three very busy members of our senior leadership team—supporting their daily operations, optimizing time management, and ensuring a smooth flow of information across the company.

You will be the trusted point of contact between them and a variety of internal and external stakeholders. You will also perform various administrative tasks, sometimes on tight deadlines, and will be required to manage your workflow autonomously across the 3 Directors, prioritising and re‑prioritising as necessary.

This is a remote‑first position that requires a high degree of discretion, initiative, self‑management, professionalism, and confidentiality. Language proficiency in English is required, as our working language is English. Proficiency in other languages, particularly German, French, or Spanish, is an advantage.

We're all about transparency, and want to give you the best possible opportunity to prepare for any potential interviews. To learn a bit more about the people you'll be working most closely with, click here :
