The Manager, Cost Accounting will own and lead the cost accounting and inventory accounting functions within the Accounting team, reporting directly to the Controller. Key responsibilities include ensuring accuracy and integrity of manufacturing costs and inventory balances, supporting month-end close and budgeting processes, and providing financial insights to support operational and business decision-making.
