  • Administer TACACS+ for network device access control, including policy updates, authentication troubleshooting, and auditing.
  • Participate in on-call rotation and respond to network incidents within defined SLA windows.
  • Produce and maintain accurate network documentation, runbooks, and change records.
  • Collaborate with security, cloud, and application teams to support cross-functional initiatives.
  • Execute approved change requests following ITIL-aligned change management processes.
