The Role

We're looking for a super organised, proactive Personal Assistant to support C Suite leaders. You'll be the person who keeps everything running smoothly behind the scenes - juggling busy diaries, staying one step ahead, and handling the day-to-day detail in a fast-moving environment. It's all about bringing calm to the chaos, keeping things on track, and doing it all with professionalism and discretion.

Why This Role Matters

This role sits at the heart of keeping our leaders and teams operating at their best. By bringing structure, organisation and calm to a fast-moving environment, you'll make it easier for everything to run smoothly - from busy diaries and key meetings to major events and day-to-day operations. You'll remove friction, keep things on track, and help teams stay connected and focused on what really matters, playing a key role in how effectively we deliver and collaborate across the business.

What You'll Do

🚀 Keep leaders moving - expertly manage busy diaries, meetings, travel and priorities to make every day run smoothly

📅 Run the rhythm - organise agendas, capture actions and keep follow-ups and progress on track

🤝 Be the go-to - act as the first point of contact, handling queries with professionalism, discretion and confidence

📝 Create & coordinate - draft presentations, reports and key documents that keep everything aligned

📁 Keep things organised - manage documents, records and expenses with accuracy and confidentiality

🔍 Stay one step ahead - pull together research and insights to support informed decision-making

✈️ Make it all happen - coordinate travel, events, offsites and external engagements end-to-end

🎯 Own the details - manage logistics for visits, conferences and key moments that matter

🔗 Connect the dots - build strong relationships across teams and work closely with stakeholders and other PAs

🙌 Support the wider team - pitch in where needed and help keep everything running seamlessly

What You'll Bring

You're highly organised and able to juggle multiple priorities and deadlines with ease. With strong admin and diary management skills, you're confident supporting busy schedules and keeping everything on track.

You're a clear communicator with great attention to detail, comfortable managing stakeholders and handling sensitive information with discretion. Proactive and solutions-focused, you take ownership, work independently, and stay calm in a fast-paced environment, supported by strong IT skills across Microsoft Office and everyday tools.
