Donald Nusbaum

Donald Nusbaum serves as a Contract Specialist within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security, where he plays a critical role in executing the acquisition of professional, scientific, and technical services essential to national security operations. His responsibilities include managing the full lifecycle of contracts for complex systems engineering, cybersecurity, and research and development initiatives that support operational readiness and infrastructure integrity. Nusbaum specializes in non-commercial acquisitions under FAR Part 15, frequently handling task orders and indefinite-delivery/indefinite-quantity contracts that require technical evaluation and performance-based management. While no specific contractor relationships are currently identifiable in the data, Nusbaum’s procurement patterns indicate consistent engagement with a broad spectrum of vendors delivering specialized technical services. His work involves collaborating with firms possessing deep domain expertise in systems engineering, cybersecurity architecture, and administrative consulting, fostering partnerships grounded in compliance, performance metrics, and long-term service delivery outcomes. Nusbaum’s contracting activity reflects a strong preference for open competition, with 90.6% of awards issued without set-asides. However, he maintains a meaningful commitment to small business participation, with 9.4% of awards designated as total small business set-asides under FAR 19.5. This demonstrates a balanced approach—prioritizing competition while ensuring opportunities for small businesses to contribute to mission-critical capabilities. His primary NAICS focus areas include Custom Computer Programming Services (541511), Administrative Management Consulting (541611), and Nonresidential Building Leasing (531120), indicating a procurement portfolio centered on IT modernization, operational support services, and facility-related infrastructure. He also engages with vendors in petroleum wholesale and digital information services, reflecting the diverse technical and logistical needs of DHS operations. Nusbaum’s expertise lies in aligning acquisition strategy with evolving technological and administrative demands across federal security missions.
