The Principal Cyber Systems Security Engineer leads the incorporation of cyber survivability requirements into system architectures, ensuring systems can operate in contested cyber environments. The position emphasizes collaboration with cross-functional engineering teams and external integrators, guiding programs through the DoD acquisition process and ensuring cybersecurity is designed in from the outset rather than treated as a compliance afterthought., * Apply systems security engineering (SSE) principles across the entire system lifecycle, from requirements definition and upfront design through verification, deployment, and sustainment. * Drive the implementation of cyber survivability requirements into system architectures, leveraging standards such as NIST SP 800-160. * Develop and analyze system-level security architectures, identify vulnerabilities early in the acquisition lifecycle, and engineer appropriate mitigations. * Lead Program Protection capability development by integrating Anti-Tamper (AT), Supply Chain Risk Management (SCRM), and software assurance into overarching system designs. * Provide technical input and guidance throughout the DoD acquisition lifecycle, including engineering reviews, program milestone decisions, and verification and validation activities. * Act as a key technical contributor in program-level risk assessments, ensuring cybersecurity is an integral part of decision-making processes. * Collaborate closely with cross-functional engineering teams, including software, hardware, and DevSecOps, to ensure cybersecurity is built into systems rather than added as a later compliance measure. * Engage regularly with customers and other system integrators to ensure they understand and correctly implement technical security requirements. * Review technical implementations from partner organizations, identify gaps or issues, and clearly explain what needs to be corrected and why. * Produce and maintain clear, comprehensive technical documentation and security-related artifacts that support acquisition and engineering activities. * Perform some project management responsibilities, including tracking progress on security engineering tasks and coordinating with stakeholders to meet program objectives. * Contribute to the culture of continuous improvement by sharing best practices in secure engineering design and promoting secure-by-design principles across programs., Use of Artificial Intelligence (AI): We may use Artificial Intelligence (AI) to support parts of our hiring process, including sourcing, screening, and evaluating candidates.
