Northrop Grumman Mission Systems Mission Defense Cyber Team has an opening for a Staff Cyber Systems Engineer (CSSE) supporting the Sentinel program based out of Roy Ut. Other operating locations include Annapolis Junction, MD, San Antonio, TX, Redondo Beach, CA, Huntsville, AL, San Diego, CA, and Colorado Springs, CO.
A Cybersecurity Systems Engineer (CSSE) ensures cyber survivability attributes are implemented in system designs as it assesses/evaluates the customers’/stakeholders’ cybersecurity requirements to decompose, derive, and refine the system’s cybersecurity requirements at all levels to drive the built-in cybersecurity protections to the architecture and design. The CSSE also guides/supports the security layout / architecture and influences the security tools selection and development. The CSSE evaluates/assesses the proposed and realized implementations to identify security risks, attack surface, and verify the cybersecurity protections from the design are realized and integrated. The CSSE guides/supports the development of verification efforts to ensure the cybersecurity protections / capabilities are functional, effective, and complete. A CSSE supports the definition of security governance, and risk management.
