Margaret Tse

Margaret Tse serves as a key procurement professional within the Contract Administration Services Division of the Department of Homeland Security’s Office of Procurement Operations, where she supports the acquisition of critical professional, scientific, and technical services essential to national security operations. Her work centers on managing the lifecycle of contracts for research, systems engineering, and cybersecurity support, ensuring alignment with DHS mission objectives in physical and engineering sciences. She handles complex service-based acquisitions under FAR Part 12 and Part 36, often involving performance-based contracting and statement of work development for high-integrity technical environments. While specific contractor names are not publicly disclosed, Tse maintains consistent working relationships with a diverse pool of vendors offering scientific consulting, systems integration, and technical analysis services. Her procurement patterns reflect a balanced engagement with both large prime contractors and small business subcontractors, fostering collaborative, performance-driven partnerships that emphasize technical excellence and compliance with federal acquisition standards. Tse demonstrates a strong commitment to socioeconomic contracting, with approximately half of her portfolio allocated to total small business set-asides under FAR 19.5. This reflects a deliberate strategy to expand opportunities for small businesses in technical service sectors, prioritizing equitable access without reliance on specialized set-aside programs like 8(a) or HUBZone. Her approach reinforces DHS’s broader goals of building a resilient, diverse supplier base capable of delivering mission-critical capabilities. Her primary procurement focus lies in NAICS 541690 (Other Scientific and Technical Consulting Services), which accounts for 75% of her activity, encompassing advisory services in cybersecurity, systems engineering, and operational research. The remaining 25% involves software publishing and related digital services under NAICS 511210. Tse’s expertise centers on procuring non-commercial technical consulting, analytical support, and engineering services that directly enable DHS’s operational readiness and infrastructure integrity.
