<p>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. Implement access controls, data segregation mechanisms, and boundary protections that adhere to DoD cybersecurity frameworks (e.g., RMF, DISA STIGs, and NIST 800-53). 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. 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. 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. Prepare presentations for leadership to demonstrate system capabilities, enhancements, and risk mitigation plans. Expertise in designing secure systems for multi-level classified environments, including cross-domain solutions. Strong understanding of DoD cybersecurity frameworks, RMF implementation, and cross-network communication architectures. Proficiency in implementing encryption protocols, access controls, and security automation technologies. Exceptional analytical and problem-solving abilities to resolve integration challenges and mitigate risks. Excellent communication skills for presenting technical solutions and collaborating with leadership and engineering teams. Adaptive and forward-thinking in response to emerging threats and evolving cybersecurity 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. Familiarity with tools like Guard solutions, Trusted Virtual Environments, or cross-domain security platforms is desirable.</p>
