  • Support system hardening, patching, and configuration management in compliance with STIGs for Linux, Windows, and network devices
  • Monitor systems for security events and supporting incident response and risk mitigation activities
  • Assess security impacts of system changes and supporting configuration control boards (CCBs)
  • Collaborate with system engineers, administrators, and DevSecOps teams to integrate security throughout the system lifecycle
  • Provide cybersecurity risk input to program leadership, Authorizing Officials (AOs), and stakeholders

Requirements

  • 8+ years of professional experience in a similar position, supporting similar responsibilities
  • Professional experience with RMF, A&A, POA&M, and ATO documentation (XACTA/eMASS)
  • Hands-on experience with vulnerability scanning and compliance tracking (ACAS, IAVM)
  • Experience securing Linux and Windows systems, STIGs, patching, and system hardening
  • Knowledge of NIST 800-series publications and incident response processes
  • DoD 8570 IAT Level II or higher certification (such as Security +, CySA +, CISSP)
  • Strong analytical, communication, and collaborative skills
  • US citizenship with Active or Current (within 2 years of active) Top Secret Security Clearance with SCI eligibility
  • Bachelor's degree in Computer Science, Cybersecurity, Information Technology or STEM related field

Recommended Qualifications
