The role

As the company grows, the CEO needs a trusted right hand to protect her time and keep priorities on track. The Executive Assistant is that person: the operational backbone of the CEO’s office, anticipating needs, completing tasks and keeping the CEO focused on what matters most. The role demands discretion and sharp organisation.

What you'll do

Calendar and schedule ownership. Run the CEO’s calendar end-to-end across multiple time zones, protect time for strategic priorities, and plan complex international travel from flights and accommodation to detailed daily agendas.
Communications and first point of contact. Serve as the CEO’s gatekeeper: filter incoming requests and email, decide what reaches her, and draft or review correspondence on her behalf.
Meeting preparation and follow-up. Prepare agendas and briefing notes ahead of key meetings, capture decisions and next steps, and chase owners so nothing slips.
Administration and expenses. Manage expense reports, invoices and basic procurement linked to the CEO’s office, and keep documentation organised and easy to find.
Email, CRM and file-system hygiene. Keep the CEO's inbox, contact records and document systems clean and current — triaging and organising email, maintaining accurate and up-to-date contacts in the CRM, and ensuring files are consistently named, filed and easy to retrieve so nothing is ever lost or duplicated.
Projects and events. Take ownership of one-off initiatives on the CEO’s behalf and co-deliver leadership offsites and company events alongside the Office Manager.
High-impact presentations. Support building visually polished presentations for board meetings, investor updates and external keynotes.
Stakeholder liaison. Be the bridge between the CEO and internal teams and external partners, keeping information flowing in both directions.
Confidentiality. Handle sensitive company, financial and people information with absolute discretion.
