Marie E. Killian serves as Lead Contract Specialist within the Federal Protective Service East CCG Division 1 Acquisition Division, part of the Department of Homeland Security’s Office of Procurement Operations. In this role, she leads the end-to-end procurement lifecycle for critical security services and integrated surveillance systems essential to safeguarding federal facilities. Her responsibilities include developing solicitation documents, evaluating proposals, conducting source selection, and managing contract award and administration in compliance with FAR and agency-specific policies. She specializes in acquiring physical security personnel and advanced security systems, ensuring operational readiness and compliance with federal protection standards. Marie maintains consistent working relationships with key contractors including GXC MAX INC, FLATTER, INC, and ENPROVERA CORP, all of which provide specialized security services and technology solutions. Her procurement approach emphasizes performance-based contracting and clear statement of work development, fostering long-term vendor partnerships grounded in accountability and mission alignment. She collaborates closely with technical evaluators and program managers to ensure contractor deliverables meet stringent security and operational requirements. Her contracting patterns reflect a balanced commitment to socioeconomic goals, with approximately one-third of her awards structured as Total Small Business Set-Asides under FAR 19.5, demonstrating a deliberate focus on expanding opportunities for small businesses. While the majority of her acquisitions are unrestricted, she actively prioritizes small business participation where feasible, aligning with DHS objectives to enhance vendor diversity and resilience in the security services supply chain.
