Financial Controller

Supporting the Group Finance Director, this role sits at the heart of the business: owning the accuracy of financial reporting, keeping controls watertight, and ensuring the numbers underpinning every major decision are reliable. Day‑to‑day you will work closely with the Management Accountant during busy periods such as month end and year end, and become a familiar face beyond the finance team—helping heads of department manage budgets, track client spend, and plan effectively. As ROAST grows, you will build the financial infrastructure to carry us forward.

Key Responsibilities

• Provide control of the integrity of all financial data leaving the Finance team
• Responsibility for the company’s accounting function, including the month‑end process and balance‑sheet reconciliation
• Manage the company’s cash‑management policies
• Prepare annual statutory accounts and control accounts ready for auditors
• Ensure compliance with all statutory obligations—HMRC and beyond
• Enforce client credit limits and align client payments with agreed terms
• Build robust, scalable financial systems as the business grows, leading on systems implementation
• Assist with due diligence for business expansion and development, and roll out ROAST Group financial processes in new offices
• Lead and develop the Management Accountant
• Develop AI tools to automate reporting within the business

The Candidate

• Minimum requirement to be part‑qualified ACMA accredited (ACA/ACCA also considered) and actively working toward qualification completion to fully support the Group Finance Director
• Currently operating at Assistant FC or Management Accountant level and ready to step up to full Financial Controller responsibility
• Demonstrable experience within a medium‑sized media or marketing services agency, with clear understanding of client budgets, retainers and agency finances
• Proven balance‑sheet reconciliation experience is essential
• Strong technical and systems capability: advanced Excel at a minimum, with experience in systems implementation and process automation desirable
• Effective and confident communicator, able to engage credibly across all levels of the business and translate financial complexity into clear, actionable insight for non‑finance stakeholders
• A self‑motivated individual with sound organisational skills, ability to manage and develop a small team, and initiative to identify and act on issues without direction
• Comfortable working in a collaborative, office‑based environment; hybrid model applies, but remote working is an exception rather than the norm
