System administrator resume template: templates, keywords and bullet points that get interviews

A system administrator resume is screened twice: first by an applicant tracking system matching keywords, then by a hiring manager scanning for proof. KlarCV handles both — an ATS-safe layout that keeps every word machine-readable, plus an AI bullet assistant that turns your Windows Server / Active Directory and Linux work into quantified achievements.

The template opens straight in your workspace — even if you have never saved it before.

Keywords ATS filters expect on a system administrator resume

Paste the job ad into KlarCV and the match check shows which of these terms are missing from your resume. Typical system administrator postings filter for:

  • Windows Server / Active Directory
  • Linux
  • PowerShell / Bash
  • VMware / Hyper-V
  • Microsoft 365
  • backup & disaster recovery
  • networking (DNS, VPN, VLAN)

Bullet points system administrator hiring managers actually read

Weak bullets describe duties; strong bullets prove impact. For system administrator roles, the signals that move a resume to the interview pile are:

  • Fleet size managed (users, servers, sites) — quantify it (before → after, %, absolute numbers)
  • Uptime and patch-compliance rates — quantify it (before → after, %, absolute numbers)
  • Automation of routine admin work — quantify it (before → after, %, absolute numbers)

Structure: what goes where

One page up to ~5 years of experience, two pages beyond that. Order: contact header with GitHub/portfolio link, a two-line profile summary naming your seniority and core stack, skills grouped by category, then reverse-chronological experience with 3–5 quantified bullets per role. Education and certifications close the page. For system administrator roles, these certifications carry real weight: Microsoft AZ-104, RHCSA, CompTIA Network+.

Frequently asked questions

How do I quantify sysadmin work that is mostly maintenance?
Scale and reliability are your metrics: 'administered 400-user AD estate across 3 sites at 99.9% uptime' or 'automated patching for 120 servers, cutting manual effort 15 h/month'.
Is the system administrator resume builder really free?
Yes. You can build the resume, run the ATS keyword check and export a watermark-free PDF during the current test phase — no subscription required.
Will the template pass real applicant tracking systems?
Yes. Every KlarCV template exports real, selectable text with standard section headings — no text-in-images, no multi-column parsing traps. You can verify it yourself with the built-in ATS check before you apply.
