Shireen Belanger

Shireen Belanger serves as a Contract Specialist within GSA’s Federal Acquisition Service (FAS) Region 1, where she plays a pivotal role in executing mission-critical procurements for federal agencies requiring advanced technical and protective equipment. Her work directly supports national security and public safety objectives by acquiring specialized engineering services essential to the development, integration, and maintenance of chemical, biological, radiological, nuclear, and explosive (CBRN) defense systems, as well as high-performance apparel and technical gear for hazardous operational environments. She manages the full lifecycle of contract actions—from requirements validation and market research to award and administration—ensuring compliance with federal acquisition regulations and mission-driven outcomes. Belanger collaborates closely with a network of qualified engineering service providers, primarily firms with deep expertise in defense systems engineering, survivability design, and mission-critical infrastructure support. While no single contractor dominates her portfolio, she consistently engages with vendors possessing relevant technical certifications, security clearances, and proven experience in federal CBRN and protective equipment domains. Her contracting approach emphasizes performance-based outcomes, rigorous technical evaluation, and vendor accountability to ensure readiness and interoperability across federal stakeholders. Her procurement activity reflects a strong preference for full and open competition, with 100% of her actions classified as “No Set-Aside.” This indicates a focus on technical capability and mission suitability over socioeconomic set-asides, though she remains compliant with all applicable small business policies and may consider qualified small businesses when they meet stringent technical requirements. Belanger’s primary procurement focus lies in NAICS 541330 (Engineering Services), with an emphasis on systems engineering, test and evaluation, hazard mitigation design, and technical integration services for specialized protective systems. Her domain expertise centers on the engineering lifecycle of CBRN defense technologies, including sensor integration, survivability modeling, and performance validation for extreme operational conditions. She is a trusted advisor in translating complex operational needs into enforceable, technically sound acquisition strategies.
