Cost Component Breakdown: Dissect complex vendor invoice packages down to baseline cost elements—analyzing direct labor categories/rates, specialized material components, equipment usage fees, sub-tier vendor markups, and indirect rate applications. Engineering & Market Benchmark Reconciliation: Evaluate billed costs against baseline engineering cost estimates (IGCE), historical market data, OEM spare parts pricing, and commercial benchmarks to establish cost reasonableness for sole-source or proprietary equipment operations.

Discrepancy & Anomaly Resolution: Identify and investigate cost anomalies, unauthorized scope expansions, duplicate equipment charges, or unverified labor hours, issuing clear financial disposition memos and supporting Contracting Officers in vendor negotiations. Subrecipient & Inter-Entity Auditing: Review and reconcile inter-laboratory transfers (IEWOs) and specialized subrecipient cost submissions associated with joint national laboratory test campaigns and international training facility operations. Documentation, Audit Trail, & Reporting Maintain audit-ready cost evaluation files, rationale summaries for cost acceptance/rejection, and price-reasonableness documentation to support internal SRNL reviews, NNSA oversight, and DOE Office of Inspector General (OIG) audits. Provide concise summary briefings to Program Managers on vendor spending trends, rate variance findings, and cost-containment recommendations for high-cost equipment procurements. Education and Licensure Bachelor's degree in Finance, Accounting, Business Administration, Engineering, Construction Management, or a related field.
