System Administrator CV Example and Writing Guide

Companies want a system administrator who keeps infrastructure running, solves problems quickly and works securely. Your CV should show the size of the environment you managed and the improvements you made.

State the size of the environment

Say how many servers, users and sites you were responsible for. Separate physical, virtual and cloud environments.

Give uptime and backup results

Availability, restore tests and shorter outages are the strongest evidence for a system administrator.

Show your automation skills

Tasks you automated with PowerShell, Bash or Ansible save time. Say what you automated and how much time it saved.

What Every System Administrator CV Should Include

• Servers, users and sites managed
• Operating systems and virtualisation
• Backup and disaster recovery
• Certifications

Example Work Experience Lines

Write your experience in the same concrete, measurable way:

• "Managed infrastructure for 450 users across 3 sites and 60 virtual servers."
• "Rebuilt the backup process and introduced monthly restore tests, cutting restore time from 6 hours to 90 minutes."
