TL;DR · Senior Principal Cyber Systems Engineer

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 by evaluating stakeholder requirements, decomposing them into technical specifications, and driving built-in protections into architecture designs. The engineer will manage security layouts, influence tool selection, perform attack surface analyses, and oversee verification efforts to ensure capabilities are functional and complete. Key responsibilities include ensuring compliance with standards like CNSSI 1253 and DoD 8570 while operating in Agile and DevSecOps environments. Required expertise includes NIST 800-160, RMF assessment artifacts, and Model-Based System Engineering using tools like Cameo and IBM DOORs. The role addresses critical security risks for launch and missile defense systems, ensuring robust protection across complex digital communication networks and infrastructure.

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 while influencing the selection and development of security tools.
  • Evaluate implemented designs to identify security risks, analyze attack surfaces, and verify that cyber protections are functional and complete.
  • Ensure weapon system compliance with contractually obligated cybersecurity standards including CNSSI 1253, DoD 8570, and DoD 8510.
  • Propose and design cyber systems architecture changes with full traceability to specific requirements.
  • Provide technical guidance and oversight across teams to ensure high-quality product deliveries and successful flight test events.
  • 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 lieu of a degree.
  • Relevant fields include Systems Engineering, Cybersecurity Engineering, Computer Engineering, or Computer Science.
  • 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.
  • Direct experience with NIST 800-160 system security engineering or the system development life cycle is required.
  • Experience in systems engineering activities such as requirements decomposition, architecture, design, implementation, and verification/validation is required.
  • Experience supporting RMF assessment authorization artifacts to satisfy NIST SP 800-37 requirements is required.
  • U.S. Citizenship is required for this position.
