The Nuclear Material Control & Accountability (NMC&A) department is seeking an Accounting Manager to take overall ownership of the nuclear material accounting system functionality and lead site reporting to the Nuclear Materials Management and Safeguards System (NMMSS) at DOE Headquarters. This critical leadership position is responsible for ensuring the absolute integrity of nuclear material tracking, managing a specialized accounting team that oversees both internal material movements and external regulatory compliance. The incumbent will provide strategic oversight to ensure that all nuclear material transactions, inventories, and system updates are executed accurately, resolving any complex systemic or operational discrepancies that arise.

This role requires a deep understanding of advanced NMC&A principles, Generally Accepted Accounting Principles (GAAP), and the scientific foundations of material behavior, including nuclear material quantity calculations, chemical and physical form changes, measurement requirements, and process flows. The manager must intimately understand how these scientific and accounting aspects of nuclear material mapping impact and relate to the broader safeguards of nuclear materials. Key responsibilities include interfacing with production personnel, security teams, and IT programmers to translate complex material tracking requirements into automated system solutions. This work is essential to the site's security and mission, directly enhancing the precision of material tracking and ensuring robust safeguards across all facilities.

Evaluates, coordinates, and implements the site-wide physical inventory program in accordance with approvals and frequencies managed by the Officially Designated Federal Security Authority (ODFSA). Directs the positive assurance verification process, which relies on discrete item checking reconciled through barcode labels, barcode readers, and mobile reading devices. Ensures that inventory data collected in the field is accurately evaluated and reconciled by the accounting team, maintaining this process as a cornerstone of the NMC&A program that is heavily relied upon by multiple other disciplines.
