• Document security events and associated analysis in a ticketing system using clear and accurate technical writing to support appropriate review and action.
• Maintain regular face-to-face interaction with the customer and address customer-raised issues with little or no supervision.
• Perform system checks in a timely manner and ensure all associated documentation is complete and accurate.
• Assist senior analysts and/or managers with forecasting and modeling current threats.
• Collaborate with infrastructure, storage, database, and application teams to align network defense monitoring with CESO operational requirements as the program transitions to a secure cloud environment.

• Bachelor's degree and 2+ years of related experience; additional experience, education, or training may be considered in lieu of degree.
• Strong knowledge of computing systems, including Windows, Red Hat, and cloud environments (AWS and Azure), with particular expertise in networking, communication protocols, and common security technologies such as IDS/IPS systems and firewalls.
• Experience implementing application and hardware security settings in accordance with vendor and DISA best business practices.
