Job Summary

Join a mission-focused cybersecurity team supporting critical DoD environments. This role is a hands-on engineering leadership position responsible for architecting, deploying, and leading enterprise ACAS (Assured Compliance Assessment Solution) implementations.

This is not a tools administration role—you will own the design, deployment, and lifecycle management of enterprise vulnerability scanning capabilities while providing technical leadership across the team.

What you will do:
  • Architect, design, and lead enterprise deployment of ACAS solutions, including scanner architecture and repository design
  • Develop and implement baseline configurations aligned with DoD STIGs and cybersecurity policies
  • Own the full deployment lifecycle (design → implementation → testing → sustainment)
  • Lead system testing, validation, and integration of security tools across enterprise environments
  • Serve as the technical lead and escalation point for advanced troubleshooting and mission-impacting issues
  • Oversee, prioritize, and direct work of junior and journeyman engineers and administrators
  • Provide hands-on mentorship, training, and technical guidance to security personnel
  • Drive continuous improvement of vulnerability scanning, reporting, and compliance processes
  • Ensure alignment with DoD cybersecurity frameworks, ACAS architecture standards, and operational requirements
What you will bring: 

  • Experience

    • 10+ years of cybersecurity engineering experience (not limited to administration or operations)
    • Proven experience architecting and leading enterprise deployments of ACAS or similar vulnerability management platforms
    • Demonstrated experience designing:
      • Scanner architectures
      • Repository structures
      • Baseline configurations
    • Experience managing end-to-end deployment lifecycle of cybersecurity tools
    • 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:
  • Experience implementing ACAS in large DoD enterprise environments
  • Familiarity with Zero Trust architectures
  • Experience integrating vulnerability tools with SIEM / security analytics platforms
  • Scripting/automation experience (PowerShell, Python, etc.)
  • Background supporting mission-critical or classified environments

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
