• Excellent initiative, motivation, problem‑solving, and analytical skills with the ability to work independently and as part of a team.
• TS/SCI clearance required with the ability to obtain a CI Poly.
• Must meet DoD 8140/CSWF for 652‑Intermediate or be willing to obtain the appropriate credential within 6 months.

Preferred Requirements

• Hands‑on proficiency and expertise in configuring or operating industry‑standard cybersecurity toolsets such as ACAS, Trellix, Splunk, Rapid7, and similar solutions.
• Experience working with a wide range of vendors and technologies including Microsoft, Linux, Cisco, VMWare, NetApp, ServiceNow, etc.
• Leveraging scripting (e.g., PowerShell, Python) or automation (e.g., Ansible, Chef, Puppet) to automate the implementation, testing, verification, validation, and monitoring of systems security configurations.
