Jeffrey E. Marriott

Jeffrey E. Marriott serves as a Contract Specialist within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security’s Office of Procurement Operations. In this role, he manages the full lifecycle of professional, scientific, and technical service acquisitions critical to national security missions, including research and development in physical and engineering sciences, cybersecurity systems engineering, and operational technology integration. His work ensures compliance with federal acquisition regulations while aligning procurements with DHS’s strategic goals for systems integrity and operational readiness. Marriott routinely handles complex, performance-based contracts for high-precision technical services requiring rigorous evaluation of technical proposals, past performance, and cost realism. Marriott collaborates with a diverse range of prime contractors specializing in advanced R&D, systems engineering, and cybersecurity solutions. While no single vendor dominates his portfolio, he consistently engages firms with demonstrated expertise in federal scientific contracting, including those with proven track records in delivering classified and unclassified technical services under time-sensitive, mission-critical conditions. His working relationships are characterized by a focus on technical competence, regulatory adherence, and performance accountability, fostering long-term partnerships with vendors capable of meeting stringent DHS standards. Marriott’s contracting patterns reflect a strong preference for full and open competition, with 100% of his acquisitions conducted without set-aside restrictions. This approach underscores a mission-driven emphasis on selecting the most technically qualified providers regardless of socioeconomic status, prioritizing capability over certification-based preferences. While small business participation is not formally incentivized in his portfolio, he remains compliant with all applicable socioeconomic requirements and evaluates small business offers on equal technical merit. His primary procurement focus is exclusively under NAICS 541712—Research and Development in the Physical, Engineering, and Life Sciences (except Biotechnology). He specializes in acquiring services related to advanced materials, sensor development, systems modeling, cybersecurity architecture, and engineering analysis, ensuring DHS maintains cutting-edge technical capabilities to safeguard national infrastructure and respond to emerging threats.
