• Configure and maintain enterprise services including Active Directory, DNS, DHCP, WSUS/patch repositories, and repository servers
• Develop and maintain automation scripts and Ansible playbooks to reduce manual effort and enforce configuration consistency
• Monitor system health, performance, and security posture using available tooling; respond to alerts and anomalies proactively
• Support ISSO-led vulnerability scanning and remediation, providing technical implementation for all CAT I/II/III findings within required timelines
• Maintain backup and recovery procedures, ensuring RPO/RTO targets are met across all environments
• Build, document, and transition environments to steady-state operations following ATO, ensuring full knowledge transfer
• Support the IT Engineering Lead and ISSM during security assessments by providing technical demonstrations and collecting compliance evidence

PREFERRED QUALIFICATIONS

• Experience with VMware vSAN and Horizon/VDI environments
• Familiarity with engineering applications such as Siemens NX, Teamcenter, or other CAD/CAM/CAE software
