Position Summary
The Assistant Controller supports day-to-day accounting operations and helps maintain accurate, complete, and timely financial records across multiple entities within our group of companies. Reporting to the Controller, this role supports general ledger integrity, contributes to month-end and year-end close, and helps ensure financial information is prepared in accordance with internal policies and applicable accounting standards.
The successful candidate will work alongside the Controller and an established finance team (which includes dedicated resources for accounts payable, payroll, accounts receivable, and cash flow management), progressively taking on broader responsibilities. This role will also serve as the Controller’s backup, stepping in to cover controllership responsibilities during absences and providing continuity of the finance function. As the group continues to grow, additional opportunities will become available for the right candidate to expand their scope and advance their career.
Working closely with the Controller and cross-functional teams, this position prepares journal entries, performs reconciliations, investigates variances, and supports audit-ready financial reporting. The Assistant Controller is expected to manage competing priorities, maintain strong documentation, and actively identify opportunities to modernize processes, strengthen controls, and increase the efficiency of the close cycle, including through the thoughtful adoption of AI and automation tools.

- Cross-train with the Controller on cash flow management, financial reporting, and group-level consolidations, providing coverage and continuity as needed
- Partner with operational and technical teams across the group to investigate and resolve issues that affect financial reporting (e.g., GL coding errors, billing or provisioning discrepancies, sales-to-GL reconciliation issues)
- Champion the adoption of AI tools, automation, and modern accounting technology to streamline workflows, improve accuracy, and reduce manual effort across the finance function
