Cybersecurity Analyst III

AeroVironment•Huntsville, AL

About The Position

The Cybersecurity Analyst III supports enterprise cybersecurity operations through vulnerability remediation and security incident ticket management. The role analyzes security findings, coordinates corrective actions with technical teams, validates remediation, and supports investigation and resolution of security incidents. The analyst works independently on routine and moderately complex assignments, maintains accurate ticket documentation, and escalates significant risks or complex investigations. The position requires technical troubleshooting skills, sound judgment, and consistent follow-through from assignment through verified closure. The analyst reviews vulnerability scan results and security configuration findings, prioritizes and validates findings, identifies asset owners, and coordinates remediation with infrastructure, endpoint, network, and application teams. The role also investigates assigned security tickets, gathers and documents evidence, executes approved response procedures within delegated authority, and escalates higher-severity incidents as needed. Operational duties include maintaining ticket records, meeting response and remediation timelines, contributing to reports and dashboards, updating troubleshooting guides and playbooks, recommending process improvements, using approved scripts and automation, and supporting security assessments, audits, and compliance activities. The role requires access to information subject to ITAR and/or EAR requirements; applicants must qualify as a U.S. person or be eligible for an export license. Some positions require current U.S. citizenship due to contract requirements.
