• Conduct architecture reviews and identify security risks across software, embedded, cloud, and hardware systems
• Develop secure design standards, engineering guidance, and product security best practices
• Support secure development initiatives including code review, dependency management, secrets management, and vulnerability remediation
• Threat Modeling & Risk Assessment:
• Lead threat modeling exercises for software, embedded systems, hardware platforms, and supporting infrastructure
• Conduct cybersecurity risk assessments for products, systems, and operational environments
• Identify attack surfaces, trust boundaries, and potential exploitation paths
• Work with engineering teams to prioritize and remediate identified security risks
• Develop mitigation strategies for cybersecurity threats impacting deployed systems and sensitive technologies
• Compliance & Security Authorization:
• Support cybersecurity compliance initiatives and product authorization efforts including:
• RMF (Risk Management Framework)
• ATO (Authority to Operate)
• Export control and regulated data handling requirements
• Assist with development of system security documentation, security controls, SSPs, and assessment artifacts
