Elizabeth Walsh

Elizabeth Walsh serves as a Contract Specialist within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security, where she plays a pivotal role in executing the acquisition of critical professional, scientific, and technical services that support national security and operational readiness. Her responsibilities include managing the full lifecycle of complex procurements—from market research and solicitation development to contract award and administration—with a focus on ensuring compliance with federal acquisition regulations and advancing the agency’s mission in systems engineering and cybersecurity. She routinely handles service-based contracts requiring high technical proficiency, particularly in transit infrastructure support and computer systems design, ensuring alignment with DHS’s strategic objectives for innovation and resilience. Elizabeth works with a diverse range of contractors, primarily those possessing deep expertise in systems engineering, cybersecurity architecture, and transit operations support services. While no single vendor dominates her portfolio, she consistently engages with firms capable of delivering mission-critical technical solutions under performance-based contracting frameworks. Her procurement approach emphasizes competitive bidding, clear statement of work development, and rigorous contractor performance monitoring to ensure deliverables meet stringent federal standards. Elizabeth’s contracting patterns reflect a strong preference for full and open competition, with 100% of her acquisitions conducted without set-asides. This indicates a focus on technical capability and mission necessity over socioeconomic classifications, though she remains compliant with all applicable small business programs and actively considers qualified small businesses when they meet technical requirements. Her primary procurement focus lies in NAICS 541512 (Computer Systems Design Services) and 485999 (All Other Transit and Ground Passenger Transportation), reflecting her specialization in procuring advanced IT infrastructure, cybersecurity integration, and transit systems support services. She routinely manages contracts requiring expertise in network architecture, real-time data systems, and engineering services that enhance the integrity and interoperability of DHS-operated transportation and digital platforms.
