About You

You bring exceptional organisational skills to everything you do, managing multiple priorities with calm efficiency even when the pace is demanding. Discretion, integrity and professionalism are second nature to you - you handle sensitive information with absolute confidentiality, uphold the values and behaviours expected at the most senior level, and exercise sound judgement when managing a senior leader's inbox and calendar, knowing instinctively what to prioritise and when to escape.

Equally comfortable working across geographies and cultures, you bring strong diplomatic and interpersonal skills to every interaction, building relationships with warmth, cultural respect and genuine care for colleagues across global teams. Collaborative and proactive by nature, you maintain a positive, can-do outlook and hold your composure under pressure - modelling the kind of excellence in service delivery and continuous improvement that sets the tone for those around you.

• Proven experience as an Executive Assistant or Personal Assistant supporting senior leaders, ideally within a mission-driven, international or membership-based organisation.
