Mario F Maccarone

Mario F. Maccarone serves as a Contracting Officer within the Department of Homeland Security’s Contracting and Procurement office under the Transportation Security Administration, where he plays a pivotal role in securing mission-critical capabilities to enhance aviation and transit security. He manages the full lifecycle of acquisitions for specialized detection systems, including explosive detection apparatus, irradiation equipment, and GPS-enabled rail monitoring technologies, ensuring compliance with federal procurement regulations and strategic security objectives. His portfolio emphasizes high-integrity, technologically advanced solutions that support national transportation infrastructure resilience, requiring deep technical oversight and risk mitigation expertise. Maccarone cultivates collaborative relationships with a diverse base of vendors, including manufacturers of defense-grade detection systems, electrical infrastructure contractors, and aerospace component suppliers. While no single contractor dominates his portfolio, he consistently engages with firms possessing specialized certifications and technical certifications relevant to homeland security applications. His contracting approach prioritizes performance-based requirements, rigorous source selection, and post-award oversight to ensure delivery of reliable, interoperable systems under stringent security protocols. He maintains a balanced commitment to socioeconomic contracting, with equal portions of his acquisitions set aside for small businesses under FAR 19.5 and open to full and open competition. This reflects a deliberate strategy to foster innovation through small business participation while maintaining operational readiness. His contracting patterns demonstrate consistent engagement with small business concerns without favoring specific socioeconomic categories, promoting broad-based competition within the national security supply chain. Maccarone’s primary procurement focus centers on NAICS codes related to ordnance and ammunition manufacturing, aircraft parts and auxiliary equipment, and electrical installation contractors. He specializes in acquiring components for explosive detection systems, security-grade electronic hardware, and integrated rail surveillance technologies, demonstrating deep familiarity with defense-related manufacturing standards and federal security specifications. His technical expertise spans both hardware procurement and system integration requirements critical to layered security operations.
