Job description

• Serve as the primary liaison between the Patch Management team and Customer Support Technicians for findings requiring local or hands-on action.

• Support endpoint version control and software compliance using Tanium or equivalent endpoint-management tools.

• Troubleshoot and resolve one-off, nonstandard endpoint issues outside routine patching and vulnerability-remediation workflows.

• Track vulnerability status, document remediation actions, and report aging or at-risk findings.

• Communicate directly with customers and support technicians to clarify findings, gather system context, and confirm remediation.

• Escalate systemic patching, configuration, or compliance gaps to leadership with supporting data.

• Support continuous improvement of endpoint vulnerability-management and patch-compliance processes.

• Two to four years of experience in endpoint systems administration, vulnerability management, or a related information technology role.

• Active DoD Secret security clearance.

• DoD 8570/8140 IAT Level II certification, such as CompTIA Security+ CE.

• Working knowledge of vulnerability-scanning and remediation workflows, including ACAS, Nessus, or similar tools.

• Solid understanding of patch management concepts, endpoint configuration, and compliance practices.

• Ability to work on-site at Redstone Arsenal, Alabama.

• Experience with Tanium, including Comply, Deploy, Patch, or Connect modules.

• Demonstrated ability to independently troubleshoot complex, nonrepeatable endpoint issues rather than relying solely on documented remediation playbooks.

• Familiarity with DoD or federal compliance frameworks, including Security Technical Implementation Guides (STIGs) and ACAS reporting standards.

• Experience supporting customers in a matrixed, enterprise, or customer-facing IT environment.
