Description The Defense Sector at Leidos is looking for a
Senior Cybersecurity Architect to support a fast-paced program with Air Force Life Cycle Management Center. The
Senior Cybersecurity Architect will provide comprehensive subject matter expertise and execution of cybersecurity engineering and architecture functions in support of a weapons system program with the Air Force. This role is critical in ensuring the security and integrity of program IT infrastructure, protecting sensitive data, and mitigating cyber threats. The
Senior Cybersecurity Architect will be an integral member of the program\'s leadership team, collaborating on strategic initiatives and ensuring alignment with overall program goals. The ideal candidate will have a strong technical background in cybersecurity principles, tools, and best practices.
As the
Senior Cybersecurity Architect, you will lead the design, implementation, and governance of security solutions across our enterprise environments. This role is pivotal in ensuring the confidentiality, integrity, and availability of both on-premises and cloud-hosted assets while enabling secure innovation at scale by working closely with cloud engineers, cybersecurity analysts, and program leadership to drive continuous improvement and deliver value to the mission.
Why This Role Matters Security and compliance in defense-sector classified networks have long lived in a structural paradox: the processes designed to protect mission software are the same processes that slow it down. Manual authorization cycles. Point-in-time snapshots. Documentation that proves intent but not execution. Every program team re-solves the same compliance problems. Every platform that wants to help them has to run the gauntlet first.
What you\'ll build isn\'t a workaround. It\'s a better architecture: policy-as-code that enforces compliance at the moment of deployment, zero-trust built-in to system design from day one, continuous evidence that gives auditors real-time proof instead of point-in-time packages, and an ATO that program teams can inherit rather than pursue. The result is a security posture that\'s stronger than manual review, stricter, and more consistent. You are here to build the foundational cybersecurity architecture that the program can scale and replicate across multiple environments.
