Job description

Key Responsibilities

• Drive a disciplined, well-controlled monthly, quarterly, and annual close; identify and eliminate bottlenecks.
• Own inventory accounting end-to-end: standard costing, valuation, reserves (excess & obsolete, shrink), and period-end reconciliations.
• Partner with Supply Chain, Operations, and FP&A on cycle counts, physical inventory, and inventory variance analysis.
• Work closely with the Shared Service Center (SSC) to coordinate close deliverables, review SSC-prepared reconciliations and journal entries, and ensure consistent accounting treatment between corporate and SSC-managed processes.
• Review and approve inventory-related journal entries and account reconciliations, along with other key balance sheet reconciliations owned by the role.
• Monitor and analyze inventory trends, identifying risk areas (obsolescence, cost variances, slow-moving stock) and driving resolution.
• Standardize recurring reconciliations and reporting packages so they're repeatable rather than ad hoc.
• Identify and implement process and systems improvements (ERP configuration, automation, reconciliation tooling) to reduce manual, error-prone work.
• Serve as a subject matter resource to peers on revenue recognition (ASC 606), including SSP methodology and deferred revenue, and on financial reporting matters more broadly, helping the team work through complex or judgmental accounting questions and, as needed, drafting or reviewing technical accounting memos.
• Support external audit requests related to inventory and, where relevant, other technical accounting areas.

People & Cross-Functional Leadership

• Partner cross-functionally with Supply Chain, FP&A, Revenue Operations, the SSC, and Internal Audit to embed good controls upstream.
• Act a resource for external auditors on areas of ownership and technical accounting questions.

Required Qualifications

• CPA required (active license).
• Big 4 public accounting experience required.
• Minimum 7–10 years of progressive accounting experience, including significant time in a public company (SEC registrant) environment.
• Strong technical accounting knowledge across inventory accounting (costing, valuation, reserves), revenue recognition (ASC 606) including SSP methodology and deferred revenue, and general financial reporting under US GAAP.
• Demonstrated ability to work at the transaction/data level — reconciling GL to subledgers and source systems, and identifying root causes of variances.
• Experience working with or overseeing a Shared Service Center (SSC) or similar outsourced/offshore accounting operation.
• Strong ERP systems experience (e.g., Microsoft Dynamics 365 F&O, Oracle, NetSuite, SAP, or similar); comfort working with large datasets in Excel and ideally SQL or similar tools.
