• Execute configuration management tasks in accordance with approved change control processes, ensuring system integrity and compliance

• Serve as the initial operational support point for incidents and service requests affecting mission systems, providing timely triage and documentation

• Manage cases within the enterprise service management platform (ServiceNow), ensuring accurate logging, impact assessment, and resolution tracking

• Assess operational impact and prioritize incidents based on severity, urgency, and mission effect

• Troubleshoot system functionality, access issues, and integration points to determine root cause or appropriate escalation path

• Coordinate with engineering teams, system administrators, and mission stakeholders to resolve system outages, performance issues, or configuration discrepancies

• Contribute to operational documentation, knowledge articles, and standard operating procedures to support consistent service delivery

• Participate in training and readiness activities to maintain proficiency with evolving cyber mission systems and tools

• Leverage approved automation and AI-enabled support tools to improve monitoring efficiency, response times, and service quality
