Christopher Wallis

Christopher Wallis serves as Division Director within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security’s Office of Procurement Operations, where he oversees the strategic acquisition of critical professional, scientific, and technical services essential to national security readiness. His leadership ensures the effective execution of complex procurements in systems engineering, cybersecurity, and advanced instrumentation, aligning contract execution with mission-critical operational requirements. Wallis manages a portfolio of high-stakes acquisitions involving integrated hardware-software systems, secure network infrastructure, and R&D-driven technical solutions that support DHS’s core mission of safeguarding critical infrastructure and enhancing operational resilience. Wallis cultivates collaborative relationships with a broad spectrum of contractors specializing in aerospace systems, defense-grade computing, and mission-critical IT services. He engages with prime contractors possessing deep domain expertise in aeronautical instrumentation and systems integration, as well as Tier-1 systems integrators with proven capabilities in secure cloud architectures and real-time data analytics. His procurement approach emphasizes performance-based contracting, rigorous technical evaluation, and long-term vendor accountability to ensure sustained system integrity and interoperability across federal platforms. Wallis’s contracting portfolio reflects a strong preference for open competition, with 100% of acquisitions issued without set-aside designations. While he does not prioritize 8(a), HUBZone, or SDVOSB set-asides, his division maintains a robust vendor ecosystem that includes both large primes and qualified small businesses competing on technical merit. His approach prioritizes capability over socioeconomic status, ensuring the highest standards of performance and innovation in mission-critical procurements. His primary procurement focus lies in NAICS 334511 for search, detection, and navigation systems, and NAICS 541512 for computer systems design services. He regularly acquires advanced sensor arrays, embedded guidance systems, secure network platforms, and custom-developed engineering solutions that support DHS’s cybersecurity posture and physical systems resilience. Wallis brings deep technical fluency in systems engineering, RF and electro-optical instrumentation, and secure software development lifecycles to every acquisition decision.
