• Support general infrastructure operations including patching, monitoring, backup/DR validation, DNS/DHCP, and Active Directory tasks.
• Assist Senior Engineers with playbook-driven integration tasks such as firewall decommissioning, network enforcement, and security alignment.
• Support security-focused tasks including MFA enforcement, endpoint policy alignment, and basic vulnerability checks during onboarding.
• Participate in data discovery, migration planning, and validation for file share migrations to OneDrive/SharePoint.
• Coordinate with ISPs, telecom vendors, and hardware providers during deployments and cutovers.
• Document risks, issues, and progress using JIRA/Teams/SharePoint, escalating when appropriate.
• Contribute thorough documentation—including as-builts, updated runbooks, lessons learned—back into the Master Integration Playbook.
• Deliver end-user training and knowledge-transfer sessions at acquired sites.
