Principal or Sr. Principal Cybersecurity Systems Engineer

A Cybersecurity Systems Engineer (CSSE) ensures cyber survivability attributes are implemented in system designs as it assesses/evaluates the customers'/stakeholders' cybersecurity requirements to decompose, derive, and refine the system's cybersecurity requirements at all levels to drive the built-in cybersecurity protections to the architecture and design. The CSSE also guides/supports the security layout / architecture and influences the security tools selection and development. The CSSE evaluates/assesses the proposed and realized implementations to identify security risks, attack surface, and verify the cybersecurity protections from the design are realized and integrated. The CSSE guides/supports the development of verification efforts to ensure the cybersecurity protections / capabilities are functional, effective, and complete. A CSSE supports the definition of security governance, and risk management.
Essential Duties:

Implement and review cyber requirement decomposition, derivation, and flow down
Implement and review traceability of cyber requirements throughout a spec tree architecture
Support the architecture and design of baked in cybersecurity requirements and protections
Implement and review traceability of cyber requirements to the design & its models
Implement and review the application of cyber security profile stereotypes to a Model Based System Engineering (MBSE) Architecture
Provide cybersecurity system engineering implementation guidance and oversight to technical teams/implementers
Review and Assess stakeholder security objectives, protection needs and concerns, security requirements, and associated verification/validation methods
Implement, review and assess cybersecurity system requirements verification/validation methods
Identify and/or assess vulnerabilities and susceptibility to life cycle disruptions, hazards, and threats
Provide security considerations to inform systems engineering efforts with the objective to reduce errors, flaws, and weakness that may constitute security vulnerability leading to unacceptable asset loss and consequences
Identify, quantify, and evaluate the costs/benefits of security functions and considerations to inform analysis of alternatives, engineering trade-offs, and risk treatment decisions
Author, support and maintain cybersecurity program documentation & RMF package documentation: Cybersecurity Strategies, System Security Plans, Continuous Monitoring Plans, Risk Assessment Report, Security Control Traceability Matrix, Plan Of Actions & Milestones, etc.
Perform other duties and directed.
This position can be filled at the Principal or Sr. Principal level.
