Rex S. Shearin

Rex S. Shearin serves as a key procurement professional responsible for managing complex technical acquisitions across engineering and aerospace systems. His role centers on ensuring mission-critical capabilities are delivered through compliant, competitive contracting processes, with a strong emphasis on technical rigor and regulatory adherence. He routinely handles full-and-open competitions for high-value engineering services and specialized manufacturing contracts, aligning acquisitions with national defense and aviation system requirements. His work supports the development and sustainment of advanced aeronautical technologies, requiring deep familiarity with federal acquisition regulations and performance-based contracting methodologies. Shearin’s contractor relationships are primarily with firms possessing specialized engineering expertise and aerospace manufacturing certifications. He engages with a diverse pool of vendors, including prime contractors with demonstrated capabilities in avionics, aircraft subsystems, and precision instrumentation. While no single contractor dominates his portfolio, he consistently works with firms holding AS9100 and ITAR registrations, reflecting a preference for suppliers with robust quality management systems and defense-sector compliance. His contracting approach emphasizes technical evaluation, past performance, and manufacturing readiness over price alone. Shearin’s procurement activity is entirely focused on full-and-open competitions, with no set-asides for 8(a), HUBZone, SDVOSB, or other socioeconomic programs observed in his award history. This reflects a strategic alignment with mission-critical technical requirements where specialized capabilities are narrowly available and competition is limited to qualified industrial base participants. His approach prioritizes technical superiority and supply chain reliability over socioeconomic preferences, consistent with the nature of the systems he procures. His primary procurement focus lies in NAICS 541330 (Engineering Services), where he secures design, analysis, and systems integration support for aerospace platforms. He also frequently acquires specialized components under 336413 and 334511, including avionics, navigation systems, and auxiliary aircraft equipment. His technical domain expertise spans aeronautical systems engineering, electronic warfare instrumentation, and high-reliability electrical components, positioning him as a specialist in mission-critical defense and aviation procurement.
