Tammy E. Seidel

Tammy Seidel serves as a primary procurement lead at NASA’s Goddard Space Flight Center, where she manages complex acquisitions supporting the design, integration, and operation of advanced space systems and scientific instrumentation. Her role is central to fulfilling Goddard’s mission of advancing Earth observation, deep-space telecommunications, and planetary exploration through the acquisition of high-reliability spacecraft, sensors, and mission-critical avionics. She specializes in end-to-end contracting for spaceflight hardware and associated engineering services, ensuring compliance with NASA’s stringent technical and mission assurance standards. Her portfolio includes early-stage development contracts through full-scale production and integration, often involving multi-year, high-risk technical programs requiring rigorous systems engineering oversight. Seidel maintains strategic relationships with key contractors including Aerospace & Commercial Technologies, LLC, and the Massachusetts Institute of Technology’s Lincoln Laboratory, reflecting her focus on specialized aerospace systems integrators and research-driven engineering partners. Her procurement approach emphasizes long-term collaboration with vendors possessing deep expertise in space-grade hardware development, radiation-hardened electronics, and mission-critical software systems. She frequently engages with contractors that combine technical innovation with proven performance in space environments, fostering partnerships built on technical rigor, schedule discipline, and mission success. Seidel’s contracting activity is entirely non-set-aside, with 100% of awards issued under full and open competition. This reflects NASA Goddard’s reliance on the most technically capable entities, regardless of size or socioeconomic designation, to meet the extreme demands of spaceflight missions. While small business participation is not formally prioritized in her portfolio, all vendors must demonstrate proven capability in high-consequence aerospace environments. Her primary procurement focus lies in NAICS 336414 (Guided Missile and Space Vehicle Manufacturing) and 541330 (Engineering Services), reflecting her specialization in spacecraft assembly, test, and integration, alongside systems engineering and mission analysis. She procures advanced payloads, flight avionics, propulsion subsystems, and ground support equipment critical to Earth science and astrophysics missions, demonstrating deep expertise in space systems procurement and mission assurance protocols.
