An exceptional opportunity has arisen for a highly experienced Executive Assistant to join a prestigious private family office in Mayfair. Supporting the daughter of the Chairman of a prominent overseas conglomerate, this role is ideal for a polished, discreet, and emotionally intelligent Executive Assistant who thrives in fast-paced, high-profile environments.

Working closely with the Chief of Staff/Head of Family Office, you will act as the senior point of coordination for a team of 9–10 assistants globally, including 3 junior lifestyle PAs based in London and 3 PAs overseas. You will be the linchpin of the office, ensuring seamless communication, calendar management, and task execution across the team.

Key Responsibilities:

• Oversee and coordinate the London-based lifestyle PAs and liaise with the wider global support team.
• Ensure the Principal’s calendar is meticulously maintained and updated daily by the 6 PAs with access.
• Organise and manage a 24/7 rota system to guarantee round-the-clock coverage.
• Run daily task lists and ensure all assistants are aligned and informed.
• Provide both business and private support to the Principal, adapting to her working style while maintaining structure and efficiency.
• Assist the Head of Family Office with HR, recruitment, and budget reporting.
• Act as a steadying presence and the “glue” of the office, bringing calm to constant change.

The Ideal Candidate:

• A seasoned Executive Assistant with demonstrable experience in private family offices, supporting UHNWIs.
• Background supporting Royalty, VIPs, or aristocracy is highly desirable.
• Proven experience managing and mentoring junior PAs.
• Emotionally intelligent, level-headed, and culturally aware.
• Able to manage shifting priorities with grace and precision.

This is a hybrid role (3 days in the office) with on-call responsibilities shared on a rota basis. It offers a rare chance to work at the highest level of private support in a dynamic, international environment.
