Cybersecurity Architect

The Leidos Digital Modernization Sector is currently pursuing a new opportunity and is seeking a Cybersecurity Architect to work in Tampa, FL to play a crucial role in a landmark Zero Trust (ZT) surge initiative for our client. This is an exciting opportunity to use your experience helping the U.S. Special Operations Command (USSOCOM) Enterprise Development, Application, and Training (EDAT) mission. In this mission we are focused on providing innovative, data-driven solutions and enterprise architecture enhancements to enable seamless operations across USSOCOM's global network. The program emphasizes rapid development and deployment of technologies to enhance the mobility and readiness of Special Operations Forces (SOF) in both combat and non-combat scenarios. Key tasks include program management, application development, training support, and technology integration to maintain USSOCOM's operational edge. The EDAT program underscores agility and adaptability, ensuring SOF professionals have access to the information and tools they need to meet evolving mission requirements.

As a key member of our expert team, you will be responsible for designing, developing, and guiding the implementation of robust Zero Trust architectures. This position is integral to the initial planning and architectural definition phases of a multi-year ZT adoption, directly contributing to the security and resilience of critical SOF environments. You will translate strategic ZT objectives into tangible architectural blueprints, ensuring alignment with USSOCOM’s mission, DoD directives, and industry best practices. This role directly maps to the DoD 8140 Security Architect (Work Role ID: 652) Intermediate level, demanding deep technical expertise in cybersecurity, network architecture, and security engineering.

The Leidos Digital Modernization Sector provides a diverse portfolio of systems, solutions, and services covering land, sea, air, space, and cyberspace for customers worldwide. Solutions for Defense include enterprise and mission IT, large-scale intelligence systems, command and control, geospatial and data analytics, cybersecurity, logistics, training, and intelligence analysis and operations support. Our team is solving the world’s toughest security challenges for customers with “can’t fail” missions.

This position is a hybrid position, you will work remote / at home and need to be onsite at MacDill AFB when needed.

Primary Responsibilities:
As the Cybersecurity Architect for this Zero Trust initiative, you will:

• Design and develop comprehensive Zero Trust architectures for USSOCOM's Greenfield (SOCRATES) and Brownfield (SOFNET-U/S) IT environments, ensuring alignment with the 7-week initial surge timeline for Iplan development and supporting long-term ZT objectives.

• Translate strategic ZT goals, DoD CIO ZT PfMO's 91 target activities (FY27) and 61 advanced activities (FY33), and operational requirements into detailed architectural blueprints, security controls, and technical specifications.

• Leverage outputs from ZT assessment tools (e.g., Leidos ZTRL) and frameworks (e.g., CACI ZT Playbook) to inform architectural decisions, identify gaps, and propose remediation strategies.

• Develop and document the protection needs (i.e., security controls) for information systems and networks, ensuring secure configuration management processes are employed.

• Design architectures and frameworks for systems and networks with multilevel security requirements, considering the processing of multiple data classification levels (e.g., Unclassified, Secret, Top Secret).

• Perform security reviews of existing and proposed architectures, identify gaps in security posture, and develop security risk management plans and mitigation strategies.

• Ensure that acquired or developed systems and architectures are consistent with USSOCOM’s cybersecurity architecture guidelines and ZT principles.

• Define and document how the implementation of new systems or interfaces impacts the security posture of the current environment.

• Collaborate closely with the Project Manager, Cyber Engineers, Systems Engineers, and Network Engineers to ensure architectural designs are feasible, implementable, and integrated effectively.

• Provide expert technical guidance and recommendations on ZT technologies, security tools, and architectural best practices.

• Document and address USSOCOM’s information security, cybersecurity architecture, and systems security engineering requirements throughout the acquisition and system development lifecycles.

• Develop system security context, preliminary system security CONOPS, and define baseline system security requirements in accordance with applicable cybersecurity mandates.
