• Identify opportunities to improve system functionality, data integrity, reporting processes, and overall efficiency.
• Provide functional support to end users and assist with system-related questions and issues.
• Support ongoing system enhancements, implementations, and broader finance transformation initiatives.

• Experience with financial system integrations and mapping between source ledgers and consolidation systems.
• Experience with OneStream, Hyperion Financial Management (HFM), Hyperion, or a similar consolidation platform.
• Strong understanding of accounting principles, financial reporting, and US GAAP.
• Ability to understand financial data flows between ERP systems, general ledgers, and consolidation applications.
• Experience managing financial master data, system reconciliations, and data validation.
• Strong analytical and problem-solving skills, with the ability to independently investigate issues and identify solutions.
• Advanced Excel skills and proficiency with Microsoft Office.
• Strong communication skills and the ability to work cross-functionally with Accounting, Finance, and IT teams.
• Ability to manage multiple priorities, work independently, and meet deadlines.

Preferred Qualifications
