• Drive continuous improvement of vulnerability scanning, reporting, and compliance processes
• Ensure alignment with DoD cybersecurity frameworks, ACAS architecture standards, and operational requirements

  • Demonstrated experience designing:
    • Scanner architectures

  • Experience leading large-scale or enterprise-level implementations (multi-system / multi-team environments)
• Technical Leadership
  • Proven experience leading engineering teams or tasking junior personnel
  • Demonstrated ability to mentor, train, and develop junior/journeyman engineers
  • Experience serving as a technical escalation point for complex or mission-critical issues
• Technical Environment
  • Deep knowledge of:
    • ACAS architecture and scanning operations
    • DoD STIGs and vulnerability management processes
    • Enterprise cybersecurity engineering practices
  • Experience with system hardening, compliance validation, and security tool integration
• Certifications & Clearance
  • DoD 8140 / 8570 IAT Level II (or higher)
  • ACAS certification (required based on role)
  • Active clearance (as required by contract)

How you will wow us:
