The Role

Reporting directly to the CFO, the Finance Manager will play a pivotal role in providing accurate, timely, and insightful financial information to drive strategic decision-making across the business.

This hands-on position acts as the bridge between transactional finance and senior leadership, with ownership of the management accounts cycle, cashflow forecasting, and financial controls. It's an ideal opportunity for a qualified accountant seeking greater autonomy, influence in a dynamic, fast-scaling environment and management responsibility.

Key Responsibilities

• Prepare accurate and timely monthly management accounts, including P&L, balance sheet, and cashflow reporting.
• Post and review month-end journals, ensuring all reconciliations are complete and accurate.
• Maintain rolling cashflow forecasts and monitor daily cash movements.
• Oversee the AP and AR team, improving controls, and supporting collection processes.
• Manage payroll, pensions, and statutory submissions to ensure compliance and accuracy.
• Lead the annual statutory audit and R&D tax credit process, coordinating with external auditors and advisors.
• Support the CFO with budgeting, forecasting, and ad hoc analysis to support business strategy.
• Continuously improving processes, implementing automation, and systems upgrades to increase efficiency.
• Partner cross-functionally with commercial and operational teams to ensure alignment of financial and business priorities.
• Provide mentorship and guidance to junior team members.

What we need to see (essential):

• Fully qualified accountant (ACA, ACCA, CIMA, or equivalent).
• Proven experience owning management accounts, including month-end close, reconciliations, and variance analysis.
• Advanced Excel or Google Sheets skills, confident handling large datasets.
• Comfortable working across both transactional and analytical aspects of finance.

What we would like to see (non-essential):

• Experience in a tech or SaaS environment, ideally within a start-up or scale-up.
• Previous exposure to process automation and finance systems implementation.
• Experience mentoring or managing junior team members.
• Demonstrated ability to work cross-functionally in a fast-paced business.
