Executive Assistant to Chairman & 2 Senior Leaders

Mayfair | Stunning Offices | Career-Defining Opportunity

If you are an ambitious, polished and proactive EA early in your career, this is the role that will elevate you.

We are partnering with a highly respected, discreet and fast-evolving investment firm based in the heart of Mayfair to find an exceptional Executive Assistant to support a Chairman and two senior leaders. This is a rare opportunity to step into a visible, trusted role where you will gain exposure at the highest level of a dynamic and intellectually stimulating environment.

From day one, you will be immersed in a collaborative, high-performing culture, working from beautifully refurbished offices complete with a roof terrace – the perfect setting for both focused work and a vibrant social scene.

The Role

This is far more than a traditional EA position. You will become a true right-hand support, instrumental in ensuring the smooth running of three highly engaged and fast-moving executives.

You will:

• Seamlessly manage complex and ever-changing diaries, balancing business and personal commitments with precision
• Act as a gatekeeper and trusted liaison, building strong relationships with internal teams, clients and external stakeholders
• Coordinate meetings end-to-end, from scheduling and logistics through to preparing high-quality materials and tracking actions
• Prepare polished presentations, documents and communications to an exceptional standard
• Oversee inbox management, ensuring priorities are identified and handled efficiently
• Arrange travel, events and itineraries with meticulous attention to detail
• Manage expenses and administrative processes with accuracy and professionalism
• Support with personal administration where required, always operating with the utmost discretion

About You

This role is ideal for a graduate-calibre EA with 2–5 years’ experience in a corporate environment, ideally within financial or professional services.

You will bring:

• A naturally organised, detail-driven approach with the ability to juggle multiple priorities
• Exceptional communication skills, both written and verbal
• Confidence working with senior stakeholders and high-profile individuals
• Strong Microsoft Office skills and a high standard of presentation
• A calm, solutions-focused mindset with the ability to anticipate needs
