• Analyze complex systems, networks, software architectures, configurations, and interfaces from a cybersecurity perspective
• Identify vulnerabilities, attack techniques, system weaknesses, and potential mission impacts
• Evaluate defensive technologies and mitigation approaches; translate cybersecurity findings into actionable engineering recommendations
• Assess how cyber threats, vulnerabilities, architectures, configurations, and defensive measures may affect system and mission performance
• Partner with systems engineers, software engineers, architects, and cybersecurity professionals to incorporate cybersecurity requirements into engineering decisions
• Communicate technical findings, cyber risks, and recommended mitigations clearly to multidisciplinary engineering and customer teams
• Support the development of more secure and cyber-resilient Navy and DoD mission systems
