• Demonstrated ability to mentor, train, and develop junior/journeyman engineers
• Experience serving as a technical escalation point for complex or mission-critical issues

• Develop and implement baseline configurations aligned with DoD STIGs and cybersecurity policies
• Own the full deployment lifecycle (design → implementation → testing → sustainment)
• Lead system testing, validation, and integration of security tools across enterprise environments
• Serve as the technical lead and escalation point for advanced troubleshooting and mission-impacting issues
• Oversee, prioritize, and direct work of junior and journeyman engineers and administrators
• Provide hands-on mentorship, training, and technical guidance to security personnel
