• Develop, analyze, decompose, and maintain cybersecurity requirements, including traceability across the engineering lifecycle.
• Interpret and translate Risk Management Framework (RMF) and NIST SP 800-53 security controls into actionable system and functional requirements.
• Produce and maintain cybersecurity architecture documentation, system models, and Model-Based Systems Engineering (MBSE) artifacts.
• Assess system designs, interfaces, and proposed modifications to identify cybersecurity risks and impacts.
• Apply cybersecurity concepts, technologies, and controls to system architecture and engineering design activities.
• Define verification approaches, test objectives, and acceptance criteria to validate cybersecurity requirements.
• Support system integration and testing, including troubleshooting and resolution of cybersecurity-related engineering issues.
• Perform cybersecurity risk assessments and create associated technical documentation.
• Collaborate with software, systems, network, cybersecurity, and test engineering teams to address technical challenges.
• Support technical reviews and prepare engineering documentation for complex, mission-critical systems.

Requirements

• U.S. citizenship and an active U.S. Government Secret security clearance (an Interim Secret may be acceptable to start, pending confirmation).
• Bachelor’s degree in Engineering, Computer Science, Cybersecurity, Systems Engineering, or a related technical discipline.
• Five or more years of related systems engineering experience, including at least two years of professional cybersecurity or cybersecurity systems engineering experience.
• Experience developing, decomposing, managing, and tracing technical requirements.
• Experience applying cybersecurity principles and controls to system design, architecture, implementation, and verification.
• Knowledge of RMF and NIST SP 800-53, including interpreting security controls for technical implementation.
• Experience with requirements management tools such as IBM DOORS Next Generation (DNG) or an equivalent tool.
• Experience with MBSE and modeling tools such as Cameo, Rhapsody, or equivalent.
• Working knowledge of cybersecurity technologies and concepts including Zero Trust Architecture, SIEM, next-generation firewalls, identity and access management, and network security.
• Experience developing verification criteria, test objectives, or validation methods for cybersecurity requirements.
• Familiarity with Windows operating environments, including interactions between operating systems, applications, networks, and security controls.
• CompTIA Security+ or another qualifying DoD 8570 IAT/IAM Level II or higher approved certification.
• Ability to work independently in on-site engineering and laboratory environments.
• Strong technical documentation and communication skills.
