Job Analysis:

The Sr. Network Security Engineer role at Leidos is fundamentally designed to safeguard and modernize the Army’s expansive global network infrastructure through a complex migration project (AGUN). The candidate is expected to bring deep technical expertise in network security, particularly in firewall technologies, virtualization, and network protocols, combined with a solid understanding of DoD security standards. The migration focus implies working with legacy systems while transitioning to newer, more secure configurations, demanding strong analytical skills to assess diverse firewall policies and translate them across vendors. Beyond technical prowess, the role requires effective cross-functional collaboration with stakeholders, cybersecurity teams, and operational partners, reflecting the mission-critical and dynamic nature of military network environments. Success in this role hinges on the ability to maintain high security postures under stringent compliance regulations, troubleshoot complex network issues in a multi-vendor, multi-tenant environment, and support zero trust architectures. The necessity for clear communication skills and customer interfacing underscores the importance of translating technical complexity into actionable insights for both technical and non-technical audiences. The role’s demands for occasional travel and willingness to work non-standard shifts further illustrate the operational urgency and mission focus driving this position.
