Your opportunity to lead transformation.

Leidos is seeking an experienced Cyber Security Manager to lead cybersecurity engineering, risk management, authorization, and security operations support for the United States Coast Guard’s Command, Control, Communications, Computers, Cyber, and Intelligence Service Center (C5ISC) in Alexandria, VA. This hands-on technical leader will manage a multidisciplinary team of Information System Security Officers (ISSOs), Information System Security Engineers (ISSEs), and incident response engineering personnel supporting mission-critical AWS, Azure, and enterprise systems. The manager will work closely with Coast Guard cybersecurity leadership, authorizing stakeholders, cloud engineering and operations teams, and program management to strengthen security posture, accelerate compliant delivery, and reduce mission risk.

Ready to engineer solutions that matter?

The Cyber Security Manager is accountable for the quality, timeliness, and execution of cybersecurity activities across the USCG Cloud Modernization program. The role combines technical cybersecurity leadership, direct people management, integrated delivery planning, customer engagement, and continuous improvement. The manager must be able to challenge technical assumptions, remove blockers, and drive measurable progress across authorization, vulnerability remediation, security monitoring, and incident response—not simply administer compliance activities.

Primary Duties:

• Lead, coach, recruit, and evaluate a multidisciplinary cybersecurity team of ISSOs, ISSEs, security engineers, and incident response personnel; establish clear ownership, backups, workload priorities, and accountability.

• Oversee NIST Risk Management Framework (RMF) execution and Authorization to Operate (ATO) activities across multiple cloud and enterprise authorization boundaries, including security control implementation, assessment readiness, evidence quality, continuous authorization support, and eMASS coordination.

• Direct cybersecurity engineering across AWS and Azure environments, partnering with Cloud Engineering and Cloud Operations on secure architecture, configuration baselines, identity/access controls, encryption, network security, Zero Trust, and DevSecOps integration.

• Own a disciplined vulnerability and remediation program covering vulnerability scans, STIG compliance, findings triage, Plan of Action and Milestones (POA&M) tracking, corrective-action ownership, due dates, verification, and risk escalation.
