- Analyze error patterns and collaborate with supply chain and warehouse leaders to validate findings and recommend corrective actions.

Requirements

- Strong background in manufacturing cost accounting with advanced knowledge of inventory valuation, controls, and reconciliation practices.

- Hands-on experience performing inventory audits, annual physical inventory reviews, and transactional accuracy assessments in a warehouse or manufacturing setting.

- Demonstrated understanding of supply chain operations and how material movement affects financial records and reporting.

- Proficiency with Microsoft Excel for analysis, documentation, and reconciliation of inventory and cost data.

- Experience working with an ERP system as well as Quick Books

- Ability to investigate discrepancies through observation, documentation review, and process tracing across warehouse and accounting activities.

- Strong communication skills with the ability to present findings clearly and work effectively with operations, warehouse, and leadership teams.
