Create a Linux Administrator Resume Engineers Actually Respect
A Linux administrator resume centered on distributions, systemd, Ansible automation and incident work, with a sample resume and a detailed writing guide.
Example Linux Administrator summary
Linux administrator with six years keeping Red Hat and Ubuntu fleets healthy for payment and hosting workloads. Manages roughly 700 hosts through Ansible roles and automated provisioning, tunes storage and kernel parameters for database servers, and cut recurring security findings by more than 80% through automated errata patching. Carries the on-call pager for tier one services and writes runbooks a new administrator can follow unaided.

What actually gets this resume read
- Name your distributions and their families, since Red Hat shops and Debian shops screen for different package and service habits.
- State the host count you manage and how much of it is under configuration management rather than hand edits.
- Show one deep troubleshooting story in a bullet: the symptom, the tool you reached for, and the root cause you found.
- Put your automation tool front and center, whether Ansible, Puppet or Salt, and say how many roles or manifests you own.
- Include hardening and compliance work by name, such as SELinux policy, CIS benchmarks or STIG remediation.
- Mention on-call scope honestly: rotation size, tier of services covered, and what you changed to reduce paging.
