Technical Documentation:

Develop and maintain endpoint-security engineering documentation, Standard Operating Procedures (SOPs), configuration baselines, implementation plans, troubleshooting guides, and sustainment artifacts.

Vulnerability and Compliance Support:

Coordinate with Cyber compliance, vulnerability-management, and system-administration personnel to support implementation of applicable cybersecurity requirements, directives, remediation actions, and continuous-monitoring activities.

Cross-Functional Collaboration:

Work with Cyber team leads, Information System Security Managers (ISSMs), system administrators, network engineers, and Systems Engineering personnel to ensure endpoint-security capabilities support mission, operational, and security requirements.

Systems Engineering Support:

Provide backup, surge, and project-based support to the Systems Engineering team for enterprise Elastic engineering efforts, as mission priorities require.

Support may include technical coordination, configuration assistance, troubleshooting, documentation, integration activities, and designated implementation projects.

The successful candidate will:

Be able to develop clear technical documentation and communicate effectively with cybersecurity personnel, system administrators, engineers, management, and mission stakeholders.
