Business Assistant / Executive Assistant to CEO & Founder Job Description

4 days in the office

We are seeking an exceptional Executive Assistant to provide seamless, high-impact support to our CEO & Founder. Working for a successful scale up, this is much more than your traditional EA role. Alongside world-class executive support, you will provide structured, strategic coordination to improve prioritisation, follow-through and senior leadership delivery. This is ideal for a highly capable EA who enjoys operating at pace, thrives in ambiguity and wants exposure to selective Chief‑of‑Staff‑style responsibilities, without full COS ownership.

You will sit at the center of the business, protecting executive time, driving alignment and ensuring momentum across key initiatives.

• Act as gatekeeper, triaging requests by urgency and strategic value
• Protect focus time and maintain structure across the executive week
• Bring calm, order and rhythm to a demanding environment

• Prepare agendas, briefing packs and pre-reads
• Gather stakeholder inputs to ensure clarity of purpose and outcomes
• Track decisions, actions and accountability
• Ensure CEO and SLT are consistently well‑prepared for internal and external engagements

• Support prioritisation of key business initiatives
• Interpret commercial and financial data and present clearly
• Drive alignment across senior stakeholders
• Improve workflow, follow-through and operational efficiency

• Proven experience supporting C‑suite in a fast‑paced, high‑growth scale‑up
• Confident working with a demanding, fast‑moving senior leader
• Strong commercial awareness and comfort interpreting financial data
• Exceptional organisational and prioritisation skills
• Highly proactive and anticipate needs several steps ahead
• Strong judgement and discretion with sensitive information
• Confident communicator with senior stakeholders
• Strong technical proficiency across Microsoft Office, data presentation and AI tools

This role suits a top‑tier EA who wants to operate at a strategic level and gain meaningful exposure within a scaling financial services business.

• Annual performance bonus (cash + growth shares)
• Salary sacrifice pension scheme
• Salary sacrifice nursery voucher scheme
• Employee Assistance Programme
• High‑quality central London office
• Hybrid working (4 days in office)
