Interim Financial Controller

The Purpose

As OQC scales, our Finance function is evolving to meet the needs of an increasingly complex, international business.

As Financial Controller, you'll play a key role in strengthening our financial control environment, solving complex accounting and process challenges, and building scalable ways of working.

This is a hands‑on, delivery‑focused role where you'll take critical finance work streams from diagnosis through implementation, testing and handover.

Reporting to the Group Financial Controller, you'll operate with significant autonomy across financial accounting, control remediation, finance operations and process improvement.

You'll combine strong technical accounting expertise with a pragmatic, problem‑solving mindset. Whether you're fixing an underlying control weakness, improving the close process, establishing finance operations for a new overseas entity or strengthening how Net Suite supports the business, you'll be expected to turn complex problems into robust, sustainable solutions.

The Group Financial Controller will retain overall accountability for Group reporting, statutory reporting, tax, treasury, material accounting judgements and the wider Group control environment.

This is an initial 6 month fixed term contract with the possibility of it becoming permanent.
