Shirlee Madeloff

Shirlee W. Madeloff serves as a Contract Specialist within the Missile Defense Agency (MDA), where she plays a critical role in executing complex acquisitions for integrated missile defense systems. Her responsibilities include managing the full lifecycle of contracts—from solicitation and source selection to award and administration—ensuring alignment with national security objectives and Federal Acquisition Regulation (FAR) compliance. She primarily handles technical procurement actions involving advanced engineering services, software development, and systems integration critical to midcourse and terminal-phase interception capabilities. Her work directly supports MDA’s mission to field layered, multi-domain defense architectures through rapid innovation and rigorous testing. Madeloff maintains consistent contracting relationships with leading defense prime contractors, including Lockheed Martin Corp and Northrop Grumman Systems Corporation, who provide core missile defense technologies and systems integration services. She also collaborates with Jacobs Technology Inc. for mission-critical engineering and technical support. Her procurement patterns reflect a preference for established industry partners with proven expertise in hypersonics, radar modernization, and command-and-control systems, often leveraging indefinite-delivery/indefinite-quantity (IDIQ) and cost-reimbursement contract vehicles to accommodate evolving technical requirements. While the majority of her acquisitions are unrestricted, Madeloff demonstrates a deliberate commitment to small business participation, with approximately 10% of her portfolio allocated to Total Small Business Set-Asides under FAR 19.5. She actively promotes competition among small businesses, particularly those capable of delivering specialized technical services, though no specific socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB dominate her portfolio. Her primary NAICS focus is on Custom Computer Programming Services (541511), reflecting a strong emphasis on mission-critical software development for sensor fusion, tracking algorithms, and battle management systems. She also procures marketing consulting services (541613) and research services in biotechnology (541714), indicating a broad technical scope that extends beyond traditional defense hardware into data analytics and systems engineering support. Her expertise lies at the intersection of cybersecurity, software-defined systems, and integrated air-and-missile defense architecture.
