Experience with network automation and monitoring tools
Scripting skills using Python and/or PowerShell and understanding of IaC(Terraform, CI/CD).
Strong understanding of network security, vulnerability management, and compliance.
Excellent problem‑solving, handling escalations, and stakeholder communication skills.

Desirable

Experience with Security Service Edge (SSE) and Zero Trust architectures.
Background in healthcare or financial services.
