About The Position

The Cross Domain Solutions Expert is responsible for designing, developing, and implementing secure information systems that support Department of Defense operations across multiple security classification levels. This role ensures interoperability and data protection between networks with varying levels of classification, such as Unclassified, Secret, and Top-Secret domains. The Cross Domain Solutions Expert applies advanced cybersecurity principles, incorporates access control mechanisms, and ensures compliance with DoD security standards. Due to the sensitivity of the projects and systems, candidates must possess an active Top Secret clearance with eligibility for Sensitive Compartmented Information (SCI).

Requirements

• Security Clearance: Active Top Secret clearance with eligibility for Sensitive Compartmented Information (SCI).
• Education: Bachelor’s Degree in Cybersecurity, Computer Science, Systems Engineering, or related field. Advanced degrees are preferred but equivalent military or technical experience may be considered.
• Experience: Minimum of 7 years of experience in cybersecurity, systems engineering, or secure network implementation in DoD environments.
• Proven experience with MLS implementations, cross-domain solutions, or similar secure information systems.
• Certifications: Preferred certifications include CISSP, GIAC Certified Multi-Level Security Engineer (GMSE), or equivalent cybersecurity certifications.

Nice To Haves

• Familiarity with tools like Guard solutions, Trusted Virtual Environments, or cross-domain security platforms is desirable.

Responsibilities

• System Design and Architecture
• Design and implement secure Multi-Level Security (MLS) architectures to support classified communications and data sharing.
• Develop solutions to enable secure interoperability between systems with different security classifications while maintaining information integrity and confidentiality.
• Research and integrate advanced technologies such as cross-domain solutions (CDS), automated security mechanisms, and encryption protocols into MLS environments.
• Security Engineering and Implementation
• Implement access controls, data segregation mechanisms, and boundary protections that adhere to DoD cybersecurity frameworks (e.g., RMF, DISA STIGs, and NIST 800-53).
• Conduct continuous security assessments to identify vulnerabilities in MLS systems and design corrective solutions.
• Configure MLS solutions to prevent unauthorized disclosure, data compromise, or cross-platform security breaches.
• Compliance and Accreditation
• Ensure MLS systems comply with applicable DoD policies, FISMA, and federal guidelines for classified data protection and system interoperability.
• Collaborate with accreditation teams to achieve Authorization to Operate (ATO) for MLS systems across varying classification levels.
• Lead efforts to integrate government-mandated security standards such as Trusted Network Implementation (TNI) and Cybersecurity Maturity Model Certification (CMMC) requirements into MLS systems.
• System Testing and Integration
• Perform integration testing of MLS systems to validate security features, interoperability, and functionality.
• Coordinate with cross-functional teams to deploy MLS solutions into existing DoD platforms and networks.
• Monitor system performance post-implementation to ensure ongoing security compliance and operational efficiency.
• Collaboration and Stakeholder Engagement
• Work closely with DoD program managers, system architects, and cybersecurity experts to ensure MLS solutions meet mission-critical objectives.
• Provide technical guidance and training to DoD personnel and stakeholders responsible for MLS operations.
• Act as a liaison with external vendors and contractors for acquiring and integrating advanced MLS technologies.
• Documentation and Reporting
• Create detailed technical documentation, including security architectures, system designs, and risk assessments for leadership and accreditation teams.
• Generate reports and dashboards outlining MLS system performance, vulnerabilities, and compliance metrics.
• Prepare presentations for leadership to demonstrate system capabilities, enhancements, and risk mitigation plans.
