Interim Financial Controller

Our client, a large and well-established not-for-profit organisation based in Winchester, is looking for an experienced Interim Financial Controller to join on a six-month contract.

The finance function is going through a period of change, with a finance system replacement planned for next year. This role will take ownership of financial control and keep day-to-day operations running while that happens, reporting to the Finance Director and working closely with the Head of Financial Operations.

• Supporting the Head of Financial Operations to rebalance workload across the team
• Contributing to the design of the future finance team structure
• Strengthening processes and controls ahead of the finance system replacement
• Keeping month-end and day-to-day finance operations running smoothly through a period of change

Suitable Candidate for the Interim Financial Controller vacancy:

• Qualified accountant (ACA, ACCA or CIMA) with experience at Financial Controller level

• Strong financial control background covering reconciliations, controls and process improvement
