Role Summary

Firmus is seeking an experienced Senior Financial Accountant to lead the month-end close process and ensure the delivery of accurate, timely and insightful financial information across the Group. The role is responsible for maintaining the integrity of the general ledger, driving best-practice financial control processes and supporting the production of high-quality management reporting in a fast-paced, high-growth environment.

The Senior Financial Accountant will be responsible for managing the end-to-end month-end and year-end close process, including balance sheet reconciliations, journal processing, intercompany accounting, consolidation activities and financial analysis.
