Executive Assistant to CEO

Executive Assistant, Office of the CEO

Full‑Time | London (hybrid) | Up to £110k + Bonus

This is a career‑defining opportunity to join the Office of the CEO of a world‑leading global organisation operating at the forefront of innovation and scientific advancement.

This is not a traditional Executive Assistant role. We are seeking a true strategic business partner – someone with exceptional judgement, operational sophistication and the resilience to thrive in a high‑intensity, high‑visibility environment.

You will form part of a small, elite Assistant team supporting a globally recognised Founder & CEO. The team operates with seamless coordination across time zones to ensure 24/7 coverage and continuity.

This role requires flexibility beyond the traditional 9–5 structure and will require global travel (approx. once a month).

• Own an exceptionally complex, fast‑moving, high‑volume calendar.
• Assess the strategic weight of meetings and proactively protect CEO focus.
• Triage urgent issues and act as an escalation point.
• Coordinate with global counterparts to ensure seamless cross‑time‑zone coverage.

• Manage intricate global travel arrangements, often at short notice.
• Anticipate and mitigate logistical risks.
• Provide on‑the‑ground support internationally when required. (International travel is required in this role.)

• Act as a trusted ambassador and gatekeeper for the CEO.
• Engage with a global network of senior leaders, academics, policymakers and high‑profile stakeholders.
• Exercise impeccable judgement, discretion and diplomacy in all interactions.

• Prioritise and manage high‑volume communications.
• Ensure the CEO is comprehensively briefed and prepared for every engagement.
• Delegate and track action items to ensure momentum and follow‑through.

• Exercise autonomous decision‑making in high‑pressure situations.
• Enable calculated risk‑taking while safeguarding against missteps.

• Drive critical cross‑functional projects from inception to completion.
• Operate effectively in ambiguity and fast‑moving environments.
• Partner across business and private functions to ensure seamless operational flow.

• Design and refine scalable workflows and systems within the Office of the CEO.
• Identify operational friction and implement improvements.
• Elevate the performance and coordination of the administrative function.

This role will suit a seasoned strategic partner with significant experience supporting C‑suite leadership in a global, high‑intensity environment.

You will bring:

• A demonstrable track record supporting a Founder, CEO or equivalent principal at the highest level.
• The ability to reprioritise instantly with calm composure.
• Strategic foresight – consistently staying two steps ahead.
• A “whatever it takes” mindset, seamlessly switching between strategic initiatives and detailed execution.
• Flexibility to align with a demanding schedule, including evenings and occasional weekends when required.
• Impeccable judgement and absolute discretion.
• Resilience, emotional intelligence and low‑ego leadership.
• Experience operating across both professional and private executive spheres.
• Exceptional organisational and project management capability.
• Advanced expertise in complex calendaring, global travel logistics and modern productivity tools.

This is an opportunity to operate at the highest level of executive support – partnering directly with a globally influential leader and playing a critical role in shaping the effectiveness of the Office of the CEO.

For the right individual, this role offers unmatched exposure, impact and long‑term career acceleration.
