Sr Principal Cyber Systems Engineer (S) joins the Mission Defense Cyber Team to support the Sentinel program. This role focuses on implementing weapon system requirements to ensure cyber survivability within system designs. The engineer will decompose, derive, and refine cybersecurity requirements across all levels, while guiding security architecture and influencing tool selection. Key responsibilities include performing attack surface analysis, managing risk, and ensuring compliance with standards like CNSSI 1253 and DoD 8570. The role involves collaborating within an Agile, DevSecOps environment to develop Launch and Missile Defense systems. Required skills include proficiency in NIST 800-160, RMF assessment artifacts, and Model-Based System Engineering using tools like Cameo and IBM DOORs. The position addresses the critical challenge of securing complex defense infrastructure against cyber threats while ensuring robust functionality for warfighter advantage.

What you'll do

  • Decompose, derive, and refine system cybersecurity requirements at all levels to ensure built-in protections are integrated into architecture and design.
  • Guide and support security layout, architecture, and the selection and development of security tools.
  • Evaluate proposed implementations to identify security risks, analyze attack surfaces, and verify that cybersecurity protections are functional.
  • Ensure weapon system compliance with contractually obligated standards including CNSSI 1253, DoD 8570, DoD 8510, and AFI 17-101.
  • Propose and design cyber systems architecture changes with full traceability to requirements.
  • Provide technical guidance and oversight across teams to ensure high-quality product deliveries and flight test events meet mission requirements.
  • Perform cyber-attack surface analysis of system designs and provide recommendations to mitigate risks.
  • Participate in cybersecurity assessment activities, including the planning and execution of security penetration tests.

What we're looking for

  • Must possess a Bachelor's degree with 8 years experience, Master's with 6 years, PhD with 4 years, or 14 years of relevant experience in cyber systems engineering fields.
  • Must have an active Secret clearance and be able to obtain a Top-Secret clearance and Special Access.
  • Must be able to obtain an IASAE II certification (CISSP preferred) within six months of hire.
  • Must possess U.S. citizenship for government clearance requirements.
  • Experience with NIST 800-160 system security engineering and the system development life cycle is required.
  • Experience in systems engineering activities including requirement decomposition, architecture, design, implementation, integration, and verification/validation is required.
  • Experience supporting RMF assessment authorization artifacts to satisfy NIST SP 800-37 requirements is required.
  • Preferred qualifications include an active Top Secret/SCI clearance, Software Assurance experience, and expertise in MBSE (Cameo) or IBM DOORs.
