Job description

Partner Financial is working with a high-growth technology business operating at the forefront of an emerging and highly innovative sector. The organisation is entering an exciting phase of international growth supported by significant investment and an expanding global footprint.

This is an opportunity to join the business at an important stage of its development, as it transitions from a development-led organisation into a more mature, commercially focused and scalable operation. The finance function is evolving alongside the wider business, creating a need for an experienced Financial Controller to strengthen financial controls, resolve complex accounting issues and drive improvements across finance processes and systems.

Reporting to the Group Financial Controller, the Interim Financial Controller will take ownership of a range of financial control, accounting and remediation workstreams. This is a hands-on role suited to someone who enjoys getting into the detail, identifying the root cause of issues and implementing practical, sustainable solutions.

Key Responsibilities:

• Strengthening and enhancing the financial control environment across key finance cycles, including purchase-to-pay, order-to-cash, payroll, fixed assets and financial close.
• Leading the investigation of control weaknesses, taking issues from root-cause analysis through to implementation, testing and handover.
• Resolving complex accounting issues and balance-sheet reconciliations, identifying and addressing underlying process, system or control weaknesses.
• Supporting month-end and year-end close activities, ensuring financial information is accurate, well supported and delivered within required deadlines.
• Preparing and reviewing elements of statutory reporting, audit working papers and supporting documentation, ensuring the finance function remains audit-ready.
• Reviewing and improving finance processes, controls and procedures to increase accuracy, efficiency and scalability.
• Supporting the implementation of accounting policies and ensuring these are effectively embedded within day-to-day finance operations.
• Utilising finance systems, including NetSuite, to improve processes, strengthen controls and reduce unnecessary manual activity.
• Working collaboratively with Finance, Technology and other stakeholders to resolve systems, data and process issues affecting financial reporting.

The Ideal Candidate:

• A fully qualified accountant (ACA, ACCA or equivalent)
• Proven experience operating in a Financial Controller capacity, with a track record of identifying control weaknesses and implementing practical, sustainable solutions.
• Strong technical accounting knowledge, including a good understanding of IFRS and experience resolving complex accounting and reconciliation matters.
• Experience with NetSuite or a similar modern finance system would be beneficial.
• Ideally, exposure to an international group environment, overseas entity setup or finance transformation.
• Previous exposure to internal control frameworks such as SOX would be advantageous.
• Experience within a technology, start-up or scale-up environment would be advantageous.
