Primary Responsibilities

Manage user accounts, groups, permissions, and access controls in Active Directory and related identity-management services.
Perform system monitoring, event-log review, capacity management, and performance tuning.
Apply operating system patches, security updates, and configuration changes in accordance with approved change-management procedures.
Support vulnerability remediation efforts and maintain compliance with applicable security requirements, including STIGs and customer security policies.
Maintain server documentation, system inventories, standard operating procedures, and configuration records.
Support backup, recovery, continuity-of-operations, and disaster-recovery activities.
Investigate and resolve escalated hardware, software, operating system, and access-related incidents.
Coordinate with cybersecurity, networking, cloud, application, and service-management teams to resolve complex technical issues.
Participate in system upgrades, migrations, testing, deployments, and technology-refresh activities.
Provide technical status updates, incident documentation, and operational reports to management and government stakeholders.
Participate in on-call, after-hours, or maintenance-window support as required by the program.

Required Qualifications

Bachelor’s degree in information technology, Computer Science, Cybersecurity, Engineering, or a related field, plus 2-4 years of relevant experience; additional relevant experience may be substituted for education in accordance with contract requirements.
At least 2+ years of experience administering Windows Server, Linux, or mixed enterprise server environments.
Experience with Microsoft Active Directory, Group Policy, DNS, DHCP, file services, and access management.
Experience performing system patching, vulnerability remediation, and configuration management.
Familiarity with system monitoring, log analysis, troubleshooting, and incident-resolution processes.
Experience using ticketing and IT service-management tools, such as ServiceNow, Remedy, or a comparable platform.
Knowledge of cybersecurity principles, least privilege, secure configuration practices, and applicable security controls.
Ability to create and maintain technical documentation, procedures, and operational reports.
Strong written and verbal communication skills and the ability to work effectively in a team environment.

Microsoft, Red Hat, VMware, AWS, Azure, or other relevant technical certifications.
Experience implementing or maintaining DISA Security Technical Implementation Guides (STIGs).
Experience with VMware vSphere, virtualized environments, storage platforms, or backup and recovery tools.
Experience with scripting and automation using PowerShell, Bash, Python, Ansible, or similar tools.
