Hannah Moussa

Hannah Moussa serves as a Contract Specialist within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security’s Office of Procurement Operations, where she plays a pivotal role in executing complex professional, scientific, and technical service acquisitions that directly support national security and operational readiness. Her responsibilities include developing solicitation documents, conducting market research, evaluating proposals, and managing contract award and administration processes for high-priority R&D and systems engineering initiatives. Hannah specializes in full lifecycle contract management for mission-critical services that enhance cybersecurity infrastructure, physical science research, and engineering systems integrity across DHS components. Hannah collaborates with a broad spectrum of prime contractors and subcontractors delivering advanced technical solutions, including firms specializing in systems engineering, data analytics, and applied research. While no single contractor dominates her portfolio, she consistently engages with vendors possessing deep expertise in federal compliance, technical proposal development, and performance-based service delivery. Her working relationships are characterized by a focus on transparency, rigorous evaluation criteria, and adherence to FAR and DHS procurement policies, fostering trust and accountability across the vendor community. Hannah’s contracting activity is entirely non-set-aside, with 100% of her acquisitions conducted under full and open competition. This reflects a strategic alignment with the agency’s mandate to prioritize technical excellence and mission-critical capability over socioeconomic preferences, ensuring that the most qualified providers—regardless of size or certification—are selected based on merit and performance. Her primary procurement focus lies in NAICS 541990 (All Other Professional, Scientific, and Technical Services) and NAICS 541712 (Research and Development in the Physical, Engineering, and Life Sciences), where she procures services such as advanced modeling and simulation, cybersecurity threat analysis, engineering prototyping, and technical advisory support. Her domain expertise centers on interdisciplinary technical services that bridge scientific innovation with operational deployment in homeland security contexts.
