About the Role

Reporting to the CFO, this is a newly created Financial Controller role sitting within the OpCo, supporting the Security & Resilience Practice. The position offers significant exposure across the business and a central role in ensuring robust financial management, reporting, and control.

You will lead a small, high-performing finance team and take ownership of financial reporting, management information, and core finance processes. Alongside this, you will act as a key business partner to the Practice Director, supporting financial performance and commercial decision-making across the project portfolio.
