The ideal candidate will work closely with Systems Engineering, Software Engineering, Hardware Engineering, DevSecOps/IT, Software Assurance, Configuration Management, Test & Evaluation, Manufacturing, Program Management, and Government cybersecurity stakeholders. The Cybersecurity Engineer is responsible for helping shepherd the system from initial requirements and architecture through design, implementation, integration, cybersecurity assessment, RMF activities when applicable, qualification, production readiness, fielding, and sustainment.

• Identify applicable cybersecurity requirements derived from DoD policies, NIST publications, DFARS clauses, CMMC requirements, RMF controls, Security Technical Implementation Guides (STIGs), program protection requirements, Supply Chain Risk Management (SCRM), and customer-specific security requirements.
• Assist Systems Engineering in establishing system security boundaries, trust boundaries, information flows, external interfaces, and cybersecurity assumptions and constraints.
• Participate in system and software architecture development and design reviews.
• Evaluate system architecture for cybersecurity weaknesses and recommend practical risk-reduction measures.
• Provide cybersecurity engineering guidance for authentication, authorization, least privilege, encryption, key management, logging, auditing, secure communications, interface protection, network segmentation, and data protection.
