Team Leadership
4. Manage, coach, and support a team of four treasury professionals.
5. Set clear SLAs, develop standardised working practices, and ensure operational continuity across the team.
6. Embed a culture of accuracy, accountability, and continuous improvement.
Systems, Data & Process
7. Confidently work across multiple systems and databases, overseeing reconciliations and data integrity checks.
8. Take ownership in environments where manual intervention is required to maintain accuracy and control.
9. Identify opportunities to streamline processes and strengthen documentation and treasury controls.
What We’re Looking For
10. Strong experience as a Treasury Manager, Senior Treasury Analyst, or Assistant Treasurer.
11. Hands-on exposure to daily cash positioning, BACS/manual payments, and long-term cash forecasting.
12. Proven ability to lead and develop a small team.
13. Practical knowledge of bank account governance, mandate management, and banking operations.
14. Advanced Excel/Google Sheets skills (pivots, lookups, modelling).
