• Good knowledge of networking fundamentals (TCP/IP, DNS, NTP, DHCP).
• Scripting ability in Bash and Python for automation.
• Familiarity with virtualised environments such as VMware.
• Experience with monitoring and logging tools (e.g., Zabbix, Splunk).
• Strong Linux security expertise (SELinux, SSH hardening, certificates).
• Worked within an ITIL‑based support environment.
