Justin R. Stewart

Justin R. Stewart serves as a procurement professional specializing in high-precision technical acquisitions, with a focus on electronic instrumentation and aerospace components. He plays a critical role in executing the agency’s mission to secure advanced measurement, testing, and control systems essential for national infrastructure and defense applications. His portfolio primarily encompasses complex engineering solutions requiring stringent compliance with federal specifications, including calibrated sensors, signal processing equipment, and auxiliary aviation systems. Stewart manages the full acquisition lifecycle—from market research and solicitation development to contract award and administration—ensuring technical rigor and regulatory alignment across competitive and negotiated procurements. While no specific contractor relationships are identifiable in current data, his procurement patterns suggest consistent engagement with specialized manufacturers of electronic components and precision test equipment. He typically works with a mix of established Tier 1 suppliers and niche technical firms capable of meeting exacting performance standards, often requiring ITAR or ISO 9001 certifications. His contracting approach emphasizes technical capability over volume, favoring vendors with proven expertise in ruggedized instrumentation and low-volume, high-reliability production. Stewart’s contracting activity reflects a strong preference for open competition, with 84.3% of awards issued without set-asides. However, he actively supports small business participation, allocating 13.7% of acquisitions to total small business set-asides under FAR 19.5 and 2.0% to HUBZone firms. This balance indicates a strategic commitment to socioeconomic goals without compromising mission-critical performance requirements. His primary procurement focus lies in NAICS 334515, encompassing the manufacture of instruments for measuring and testing electrical signals, alongside related categories in electronic components and aircraft subsystems. He regularly acquires calibrated transducers, data acquisition systems, and embedded control modules, demonstrating deep expertise in electrical engineering and avionics domains. His work supports systems requiring high accuracy, electromagnetic compatibility, and environmental resilience in mission-critical applications.
