• Review and maintain onboarding/offboarding workflows, runbooks, and Freshservice automations.
• Ensure access changes are accurately executed and documented to support audit and compliance requirements.
• Lead onboarding sessions ensuring that customers have setup their workstation successfully and have access to all associated applications required for their role.

Backup Awareness & Infrastructure Support

• Monitor Veeam backup job status and elevate failures or anomalies to the infrastructure team promptly.
• Support basic infrastructure health monitoring (Zabbix or equivalent) and report anomalies as needed.
• Assist with patch management cycles and vulnerability remediation tracking in NinjaOne and Intune.
