Marco Macherelli

Marco Macherelli serves as a secondary procurement specialist within the Office of Procurement Operations at the Department of Homeland Security, supporting the agency’s mission to secure critical infrastructure through strategic acquisition of advanced technical services. While not the primary contracting officer, he plays a vital role in coordinating complex procurements for cybersecurity-enabled IT systems, cloud infrastructure, and workforce development solutions. His responsibilities include conducting market research, evaluating technical requirements, and facilitating interdepartmental alignment to ensure acquisitions align with national security priorities. He routinely handles high-stakes, mission-critical contracts requiring compliance with federal acquisition regulations and risk mitigation protocols. Macherelli maintains consistent working relationships with leading national security contractors including PARAGON SYSTEMS INC, TRIPLE CANOPY INC, BATTELLE NATIONAL BIODEFENSE INSTITUTE, LLC, DELOITTE CONSULTING LLP, and THE MITRE CORPORATION. These partnerships are characterized by deep technical collaboration, particularly in areas such as threat intelligence platforms, secure cloud migration, and systems engineering for homeland defense applications. His engagement with these firms reflects a preference for established, high-capacity vendors with proven track records in federal cybersecurity and biodefense domains, often supporting long-term, performance-based acquisition strategies. His procurement patterns show a strong preference for open competition, with 80% of acquisitions issued without set-aside designations. However, he actively supports small business participation, with 20% of contracts awarded under Total Small Business Set-Asides in accordance with FAR 19.5, demonstrating a balanced approach to market access and mission readiness. Macherelli’s primary procurement focus lies in NAICS 541512 (Computer Systems Design Services), 541511 (Custom Computer Programming Services), and 511210 (Software Publishers), reflecting expertise in tailored cybersecurity solutions, secure software development, and analytical systems. He also regularly procures specialized analytical laboratory instrumentation under NAICS 334516, indicating engagement with forensic and biothreat detection technologies essential to DHS operational resilience.
