• Maintain a robust financial control environment, overseeing risk management, tax compliance, statutory reporting and audit activities.
• Own the month-end and year-end close processes, balance sheet integrity and working capital management, ensuring accurate reporting, effective controls and strong cash performance.
• Oversee treasury activities including banking relationships, cash management, liquidity planning and payment controls.
• Oversee VAT, PAYE and corporation tax compliance, coordinating with external advisers where required.
• Develop and maintain financial policies, procedures and governance frameworks to support a strong internal control environment.
• Lead finance transformation initiatives, including process improvement, automation, system optimisation and implementation projects to improve efficiency, scalability and controls.
• Partner with senior stakeholders and FP&A to provide financial insight, performance analysis and decision support across the business.
• Partner with FP&A on cash flow management and budgeting & forecasting rounds.
