Jennifer D'Addio

Jennifer A. D’Addio serves as a Contract Specialist within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security, where she plays a pivotal role in executing complex procurements of professional, scientific, and technical services critical to national security operations. Her responsibilities encompass the full lifecycle of contract actions—from solicitation and evaluation to award and administration—ensuring compliance with FAR regulations and alignment with DHS’s mission to enhance systems integrity and operational readiness. She primarily manages acquisitions in engineering, cybersecurity, and advanced instrumentation, supporting R&D initiatives in physical and engineering sciences that underpin federal infrastructure resilience. While specific contractor names are not disclosed, D’Addio maintains consistent working relationships with a diverse pool of vendors specializing in systems engineering, technical consulting, and computer-related services. Her procurement approach emphasizes performance-based contracting, clear statement of work development, and rigorous source selection processes, fostering transparent and accountable vendor partnerships grounded in technical competency and regulatory compliance. D’Addio’s contracting patterns reflect a strong preference for unrestricted competition, with 95.5% of her actions awarded without set-asides, indicating a focus on maximizing technical capability and market competition. However, she actively supports small business participation through the 4.5% of awards designated as Total Small Business Set-Asides under FAR 19.5, demonstrating a balanced commitment to both mission efficacy and socioeconomic objectives without relying on specialized programs like 8(a), HUBZone, or SDVOSB. Her technical focus centers on NAICS 334519 (Other Measuring and Controlling Device Manufacturing), reflecting procurement of specialized instrumentation and control systems, complemented by significant activity in 541519 (Other Computer Related Services) and 541330 (Engineering Services). She regularly procures custom software solutions, systems integration services, and technical consulting that support cybersecurity, sensor deployment, and mission-critical engineering applications across DHS components.
