William B. Grimm serves as a Contract Specialist within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security, where he plays a pivotal role in executing complex procurements for professional, scientific, and technical services critical to national security operations. He manages the full lifecycle of contracts for high-priority acquisitions in systems engineering, cybersecurity, and advanced instrumentation, ensuring alignment with federal acquisition regulations and DHS mission objectives. His work directly supports operational readiness by securing specialized expertise in physical and engineering sciences, with a focus on delivering technically rigorous, compliant, and mission-critical solutions. Grimm cultivates strategic partnerships with a broad spectrum of vendors, primarily engaging firms specializing in technical consulting, systems integration, and precision manufacturing.

He maintains a collaborative, compliance-driven relationship model, emphasizing performance-based contracting and rigorous source selection processes to ensure technical adequacy and value. His procurement approach prioritizes open competition, with 94.3% of awards issued under non-set-aside authorities. Nevertheless, he actively supports socioeconomic goals, consistently allocating approximately 2.9% of his portfolio to Women-Owned Small Businesses and another 2.9% to total small business set-asides under FAR 19.5, demonstrating balanced adherence to federal small business participation mandates without compromising mission requirements. Grimm’s primary procurement focus lies in NAICS 541690 (Other Scientific and Technical Consulting Services) and 541611 (Administrative Management Consulting), reflecting strong demand for advisory services in systems engineering and operational planning. He also regularly procures specialized equipment under NAICS 334519 and 334511, indicating deep engagement with the development and acquisition of advanced measurement, navigation, and control systems. His technical domain expertise spans cybersecurity infrastructure, engineering diagnostics, and mission-critical instrumentation, positioning him as a key facilitator of DHS’s science and technology modernization efforts.
