• Lead development and optimization of complex LAN/WAN, SD-WAN, and hybrid cloud network environments supporting mission operations
• Architect and oversee routing protocols (BGP, OSPF, EIGRP), traffic engineering, segmentation, and network convergence strategies
• Ensure high-performance, low-latency, and resilient network transport across geographically dispersed and contested environments
• Lead advanced troubleshooting and root cause analysis of complex network issues impacting mission-critical services
• Oversee integration of network security controls including firewalls, VPNs, encryption (e.g., TACLANE), and secure transport mechanisms
• Guide implementation of network segmentation, micro-segmentation, and secure enclave design aligned to Zero Trust and multi-domain requirements

Cybersecurity Leadership & Integration:

• Lead and oversee technical security assessment activities across the enterprise, ensuring identification of vulnerabilities, non-compliance, and systemic risks
• Establish and enforce cybersecurity design standards and ensure integration of security requirements across all engineering disciplines
• Provide leadership in validating system security requirements, architectures, and designs, ensuring alignment with enterprise security policies and mission needs
• Oversee the design and integration of Information Assurance (IA) and cybersecurity capabilities across networking, computing, and enclave environments, including multi-enclave and multi-classification systems
• Ensure cybersecurity is embedded throughout the system lifecycle, from architecture through deployment and sustainment
• Guide architects and engineers in implementing appropriate security controls and capabilities to ensure consistent application of enterprise security policy
• Lead development and maturation of enterprise security architecture, including Zero Trust and cross-domain solutions
• Establish and enforce trusted relationships among external systems, partner networks, and integrated architectures
• Oversee risk management activities, ensuring threats and vulnerabilities are identified, assessed, and mitigated throughout the program lifecycle
• Provide leadership support for RMF, ATO, continuous monitoring, and compliance activities, ensuring adherence to DoW STIGs and cybersecurity frameworks
• Contribute to security planning, risk analysis, certification, and awareness efforts across system and network operations

Service Delivery & Operational Integration:

• Ensure modernization solutions are aligned with ITIL 4 practices, including service level management, incident response, problem management, and continual improvement
• Drive integration of modernized capabilities into operational environments, ensuring sustainment, monitoring, and lifecycle management
• Collaborate with Service Delivery and Operations leadership to ensure solutions meet operational performance requirements and mission needs
• Establish metrics and reporting frameworks aligned to SLAs, KPIs, and mission outcomes

Leadership & Team Integration:

• Lead, mentor, and provide technical direction to engineers, cybersecurity personnel, and technical staff across all program areas
• Coordinate cross-functional teams to deliver integrated solutions across network, systems, cybersecurity, and operations domains
• Provide input to performance evaluations, tasking, and workforce development planning
• Foster a culture of accountability, collaboration, and continuous improvement aligned with mission execution

Required Qualifications:

• Bachelor's degree and 8+ years of experience (or 11 years of experience without a degree)
• Top Secret security clearance
• Certification: CISSP
• Extensive experience leading enterprise IT modernization efforts across network, system, and cybersecurity domains
• Demonstrated expertise in designing and implementing complex network architectures at an enterprise scale
• Expert-level knowledge of routing, switching, and network design principles consistent with CCIE-level capability
• Strong experience integrating cybersecurity into enterprise architectures and system design
• Deep knowledge of RMF, ATO processes, continuous monitoring, and DoW cybersecurity frameworks
• Knowledge of DoW STIGs, Zero Trust architecture, and multi-security domain service delivery
• Experience operating within multi-enclave and multi-classification environments
• Proven ability to lead and integrate cross-functional engineering teams

Desired Skills:

• CCIE certification or equivalent experience strongly preferred
• Experience supporting Mission Partner Environment (MPE) or coalition operations
• Knowledge of Cross Domain Solutions (CDS) technologies
• Experience with cloud and hybrid architectures (AWS, Azure, GovCloud)
• Familiarity with ITIL 4 practices and enterprise ITSM platforms (e.g., ServiceNow)
• Experience supporting operational command and control (C2) or CJADC2 initiatives
• Strong executive communication skills with ability to engage senior leadership and technical teams
