The ideal candidate will work closely with Systems Engineering, Software Engineering, Hardware Engineering, DevSecOps/IT, Software Assurance, Configuration Management, Test & Evaluation, Manufacturing, Program Management, and Government cybersecurity stakeholders. The Cybersecurity Engineer is responsible for helping shepherd the system from initial requirements and architecture through design, implementation, integration, cybersecurity assessment, RMF activities when applicable, qualification, production readiness, fielding, and sustainment.

· Identify applicable cybersecurity requirements derived from DoD policies, NIST publications, DFARS clauses, CMMC requirements, RMF controls, Security Technical Implementation Guides (STIGs), program protection requirements, Supply Chain Risk Management (SCRM), and customer-specific security requirements.

· Participate in system and software architecture development and design reviews.

· Evaluate system architecture for cybersecurity weaknesses and recommend practical risk-reduction measures.

· Ensure authorization documentation accurately represents the actual engineered and production system rather than treating RMF documentation as a separate compliance activity.

· Working knowledge of NIST SP 800-53, NIST SP 800-37 RMF, NIST SP 800-171, NIST SP 800-218 Secure Software Development Framework (SSDF), and applicable DoD cybersecurity requirements.

· Understanding of DoD RMF processes and security control implementation.

· Experience developing cybersecurity requirements and verification criteria.

· Ability to translate cybersecurity requirements into language understandable to engineering, manufacturing, test, and program personnel.

· Experience with cybersecurity risk assessment and vulnerability management.

· Knowledge of secure software architecture and secure coding concepts.

· Understanding of Linux security and system hardening.

· Experience with vulnerability assessment technologies such as ACAS, Nessus, SCAP/STIG tools, or equivalent platforms.

· Familiarity with SAST, DAST, SCA, dependency scanning, secrets scanning, and software supply-chain security.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
