Northrop Grumman’s Aeronautics Systems sector is seeking a Cyber Systems Engineer (Principal or Senior Principal Level) to join our team of qualified, diverse individuals in defining the future. This position will be located in Rancho Bernardo, CA or Redondo Beach, CA.
In this role, you will play a pivotal role in both new system development and the ongoing sustainment of existing platforms by applying a solid working knowledge of the Risk Management Framework (RMF) to identify, assess, and mitigate cybersecurity risks. You will design, develop, integrate, test, and verify system‑security solutions, ensuring that each RMF step, from categorization through continuous monitoring produces the required artifacts: Security Assessment Plan (SAP), Security Assessment Report (SAR), Risk Assessment Report (RAR), System Security Plan (SSP), Plan of Action & Milestones (POA&M), Security Control Traceability Matrix (SCTM), and Continuous Monitoring (ConMon) documentation needed to obtain and sustain an Authority to Operate (ATO).
This role requires hands‑on experience with NIST SP 800‑53 and a solid understanding of the Systems Development Life Cycle (SDLC), including the key engineering milestones (PDR, CDR, SFR, TRR) and the associated cybersecurity deliverables required at each engineering phase. The ideal candidate will be proficient in creating and maintaining the full suite of compliance documentation, adept at embedding security controls directly into development pipelines, and possess strong communication skills to work effectively with architects, developers, program managers, and auditors throughout the acquisition and systems development lifecycles.
You will also be expected to understand:
Direct experience developing RMF assessment and authorization artifacts in accordance with NIST SP 800-37
Hands on experience using security compliance tools (e.g., ACAS, SCAP, STIG, SCC),
