At Smiths Detection, we are building a standalone Treasury function that will support our global business through robust financial control, accurate reporting, and modern treasury operations. As part of this exciting transformation, we are looking for a Treasury Accountant to join us on a 12-month fixed term contract based at our new offices in Chancery Lane, London. This is a hybrid role, where you would be expected onsite a minimum of 3 days a week.

This is a unique opportunity to play a key role in establishing and enhancing treasury accounting processes within a newly created team.

What you will be doing:

Treasury Accounting & Reporting

• Perform month-end valuation calculations for FX transactions and reconcile treasury positions to the general ledger.
• Maintain treasury balance sheet reconciliations and support reporting requirements.

• Identify opportunities to automate manual treasury accounting activities.
• Document processes, controls, and procedures to support a scalable operating model.
• Operate key treasury accounting controls and reconciliations.
• Investigate and resolve accounting and settlement exceptions.
• Partner with Treasury, Finance, Tax, and international stakeholders to drive improvements in process efficiency, reporting accuracy, and financial control.
