• Working knowledge of platform security, RBAC, secrets management, compliance scanning and vulnerability remediation using tools such as HashiCorp Vault or CyberArk.
• Comfortable working in an Agile squad, using Jira, Confluence, ServiceNow and Teams to manage work, incidents, change and stakeholder engagement.

Desirable

• Experience with Dell PowerEdge infrastructure, iDRAC, firmware planning and platform hardware expansion.
