E. Darlene Bullock

E. Darlene Bullock 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 and operational readiness. Her responsibilities include managing the full lifecycle of complex contracts for systems engineering, cybersecurity support, and research and development services, ensuring compliance with federal acquisition regulations and mission-driven outcomes. She plays a central role in aligning procurement strategies with the agency’s objectives to maintain systems integrity and advance technical innovation across DHS missions. Bullock’s contractor relationships are primarily with large, established firms providing high-assurance technical services, though she maintains a disciplined, non-set-aside procurement posture that prioritizes competitive, open bidding. While no single vendor dominates her portfolio, her contracting patterns reflect a preference for experienced contractors with proven capabilities in engineering, IT infrastructure, and administrative support services. Her working relationships emphasize performance-based outcomes, rigorous oversight, and adherence to FAR compliance, fostering a transparent and accountable acquisition environment. Her set-aside preferences are overwhelmingly focused on open competition, with 97.5% of acquisitions conducted without socioeconomic set-asides. Only minor portions—each approximately 0.8%—are allocated to 8(a), total small business, and service-disabled veteran-owned small business (SDVOSB) set-asides, indicating a strategic emphasis on merit-based selection rather than socioeconomic preferences, while still maintaining statutory compliance. Bullock’s procurement focus centers on NAICS 541611 (management consulting services), 561110 (office administrative services), and related categories supporting operational infrastructure. She routinely acquires professional services in administrative management, facility leasing, and employment placement support, reflecting a technical domain expertise in sustaining mission-critical back-office functions that enable frontline DHS operations. Her work ensures efficient resource allocation to sustain the agency’s long-term readiness and service delivery capabilities.
