Audit, Controls & Financial Operations

- Serve as a key point of contact for external auditors and tax advisors.
- Coordinate audit planning and preparation of audit schedules, information requests, and supporting documentation for the consolidating audit.
- Respond to auditor requests and questions in partnership with appropriate internal stakeholders.
- Track and resolve audit findings and recommendations.
- Maintain and strengthen internal controls over accounting, cash, payments, banking, payroll accounting, and financial reporting and develop and maintain accounting policies, procedures, and documentation that support consistent practices across entities.
- Oversee accounting platforms for accounts payable, receivables, payroll, benefits, and other financial operations, ensuring accurate reconciliation to the general ledger.
- Identify and implement opportunities to improve, automate, and scale recurring accounting, reconciliation, reporting, and financial processes.
- Support accounting-system implementations, integrations, and other Finance initiatives as needed.

Required Qualifications
