William Mallison serves as a key procurement professional within the Contract Administration Services Division of the Department of Homeland Security’s Office of Procurement Operations, where he supports the acquisition of critical professional, scientific, and technical services essential to national security operations. His responsibilities include managing the full lifecycle of contracts for engineering, cybersecurity, and systems integration services, ensuring compliance with federal acquisition regulations and alignment with DHS’s operational readiness goals. He specializes in complex service-based acquisitions that require rigorous technical evaluation and performance-based contracting methodologies. Mallison maintains collaborative relationships with a broad spectrum of contractors, including large prime contractors with deep expertise in systems engineering and scientific research, as well as niche firms providing specialized technical consulting and training services. His contracting patterns reflect a preference for performance-based, outcome-driven agreements that emphasize deliverables over inputs, fostering accountability and innovation. He frequently engages with vendors capable of delivering high-integrity technical solutions under strict security and compliance protocols. His procurement strategy prioritizes open competition, with 89.2% of acquisitions conducted without set-asides, reflecting a focus on technical capability over socioeconomic classifications. Nevertheless, he actively supports small business participation, with 8.1% of awards designated as total small business set-asides and 2.7% awarded to women-owned small businesses, demonstrating a measured but intentional commitment to socioeconomic goals within a mission-critical acquisition environment. Mallison’s primary procurement focus lies in NAICS 531120 (nonresidential building lessors), indicating significant activity in facility-related support services, alongside substantial investment in NAICS 511210 (software publishing) and 541618 (management consulting). His portfolio reflects expertise in procuring cybersecurity infrastructure, technical training, and engineering services that underpin DHS’s systems integrity and research initiatives, with a clear emphasis on mission-critical technical domains.
