Sabrina J. Heislup

Sabrina J. Heislup serves as a Contract Specialist at the Defense Threat Reduction Agency (HDTRA1), where she plays a critical role in executing complex acquisitions to support the agency’s mission of countering weapons of mass destruction and emerging national security threats. She manages the full lifecycle of procurement actions, from requirements validation and market research to contract award and administration, with a primary focus on technical services that enhance threat detection, forensic analysis, and operational response capabilities. Her acquisitions are strategically aligned with the agency’s scientific and engineering priorities, ensuring timely delivery of mission-critical solutions through compliant, risk-managed contracting practices. Heislup maintains longstanding relationships with key industry partners including TECHTRANS INTERNATIONAL INC, BATTELLE MEMORIAL INSTITUTE, AERIS LLC, APPLIED RESEARCH ASSOCIATES, INC., and AMAZON WEB SERVICES, INC. These collaborations reflect a preference for high-caliber technical vendors with proven expertise in defense science, cybersecurity, and advanced computing. Her contracting approach emphasizes performance-based outcomes, leveraging firm-fixed-price and cost-reimbursement structures to align vendor deliverables with evolving operational needs. She consistently engages contractors with deep domain knowledge in chemical, biological, radiological, nuclear, and explosive threat mitigation. Heislup’s procurement portfolio is entirely non-set-aside, with 100% of awards issued under full and open competition. This reflects a strategic emphasis on accessing the broadest possible pool of technical expertise to meet mission-critical deadlines and performance standards, rather than prioritizing socioeconomic set-asides. While small business participation is not structurally mandated in her portfolio, she ensures compliance with all applicable small business subcontracting requirements. Her primary procurement focus is on NAICS 541511 (Custom Computer Programming Services), underscoring her specialization in software development, data analytics, modeling and simulation, and secure cloud-based systems for threat intelligence and operational support. She consistently procures tailored solutions that integrate artificial intelligence, machine learning, and secure infrastructure to enhance the agency’s ability to detect, analyze, and neutralize high-consequence threats.
