The Leidos Health and Services Sector is seeking an experienced Senior Cybersecurity Architect to lead the security strategy, architecture, governance, and secure engineering practices supporting CDC National Healthcare Safety Network (NHSN) Microsoft Azure cloud platform and enterprise software ecosystem.

Candidates MUST:

be a US Citizen or US Person (Green Card Holder) who is currently located in the United States for the current three consecutive years with the ability to obtain a Public Trust Security Clearance.

Role is primarily remote but will require some onsite work in Atlanta, GA- strong preference for local candidates.

This role will establish the cybersecurity foundation for NHSN's modernization strategy by creating a comprehensive security architecture, embedding security throughout the software development lifecycle, strengthening Azure cloud governance, securing enterprise data platforms, and enabling the responsible adoption of emerging technologies. The Senior Cybersecurity Architect will help transform NHSN from a reactive security posture to a mature, proactive, and governance-driven cybersecurity program that supports the agency's public health mission.

The successful candidate will serve as the program's principal cybersecurity authority, responsible for establishing a comprehensive security framework that protects modern cloud-native applications, legacy platforms, data engineering environments, software delivery pipelines, and emerging technologies, including artificial intelligence. This individual will partner closely with software engineers, cloud engineers, data engineers, architects, and program leadership to ensure security is designed into every aspect of the platform.

The ideal candidate combines deep software engineering expertise with enterprise cybersecurity architecture experience and knowledge of requisite security frameworks and controls required of government systems and possesses the technical leadership required to establish a proactive, governance-driven security program.

• Support Authority to Operate (ATO) activities and security documentation.

Emerging Technology Security

• Develop security guidance for artificial intelligence and other emerging technologies supporting NHSN modernization.
• Evaluate risks associated with AI systems, including prompt injection, model security, data protection, supply chain risk, and secure integration patterns.
• Establish security guardrails enabling responsible adoption of AI capabilities across the organization.

Security Culture and Technical Leadership

• Develop and deliver cybersecurity education and awareness training for engineering and program teams.
• Mentor software engineers, cloud engineers, and technical leads on secure engineering principles.
• Create reusable security standards, design patterns, playbooks, and implementation guidance that establish a consistent security posture across NHSN.
• Serve as the trusted cybersecurity advisor to program leadership on emerging threats, technology investments, and enterprise security strategy.

Required Qualifications

• Bachelor's degree in Computer Science, Cybersecurity, Software Engineering, Information Technology, or a related discipline (Master's degree preferred).
