How to get a Systems Administrator Resume past the ATS

  • Include both abbreviations and full terms for technologies (e.g., 'Active Directory (AD)' and 'DHCP (Dynamic Host Configuration Protocol)') as ATS may search for either variant
  • List operating system versions explicitly (Windows Server 2016/2019/2022, RHEL 7/8, Ubuntu) rather than generic 'server administration' to match precise job requirements
  • Incorporate action verbs specific to systems work: 'administered', 'deployed', 'configured', 'maintained', 'migrated', 'automated', 'troubleshot', 'monitored'
  • Place technical skills in both a dedicated Skills section and within job descriptions, as some ATS weight context-embedded keywords more heavily
  • Use exact scripting language names (PowerShell, Bash, Python) rather than 'scripting experience' to trigger technical filters
  • Match infrastructure scale descriptors from job postings (e.g., 'enterprise environment', '500+ users', 'multi-site infrastructure') to demonstrate relevant experience level
