• Developing and mentoring a team of 2–3 junior finance colleagues, holding them accountable and elevating standard accounting practices.
• Overseeing banking, payments, bookkeeping, accounts payable, and core finance operations controls.
• Identifying weak, manual, or fragile processes and rebuilding them into scalable, automated workflows.
• Utilising AI, modern workflows, and systems tools hands-on to improve reporting speed, accuracy, and documentation.
• Acting as senior finance cover and a trusted number-two partner to the Group Finance Director.
• Bringing independent judgement and constructive challenge where numbers, controls, or processes require optimisation.

• Demonstrated leadership capability in managing, developing, and raising standards in a small finance operations team.
• Robust project management and change delivery capability, especially in audits or finance transformation initiatives.
• An innovative, hands-on automation mindset, with practical experience utilising Excel automation, workflow tools, AI, Power Query, or modern finance systems.
• A rigorous control mindset accompanied by exceptional attention to detail.
• A confident and diplomatic communication style, enabling you to form independent views and respectfully challenge senior leadership.
• Excellent written and verbal communication skills, with a comfort operating in a fast-paced, detail-focused environment.
