Systems Administrator CV Examples & Writing Guide

A systems administrator CV gets an interview when the IT manager can see, in one screen, which platforms you ran (Windows Server, Linux, Active Directory, VMware, Azure or AWS), at what scale (servers, users, sites), and what you kept running or fixed, with numbers such as uptime, ticket volume, patch compliance and backup success rate. Certifications go near the top.

Systems administrator CV example (Windows and Linux, 6 years)

A CV for a sysadmin with about six years of experience in a mid-sized company, written the way an IT manager reads it: environment first (what you ran and how big it was), then what you did to it. The name and employers are made up; the numbers are the kind you can pull from monitoring, ticketing and patch reports.

Every bullet names the platform, the scale and a number. "Managed servers" tells an IT manager nothing; "140 VMs on a 3-host vSphere cluster at 99.95% uptime" tells them exactly what level you are.

What IT managers check first on a sysadmin CV

A sysadmin CV gets two readers: a recruiter who matches keywords, and an IT manager who judges whether you have run an environment like theirs. Both spend under a minute on the first pass.

  • Platform match. Windows, Linux or both? On-premises VMware, Azure, AWS or hybrid? If the job advert says Windows Server, Active Directory and Azure and your CV leads with Ubuntu and AWS, you are filtered out before anyone reads a bullet. Put the environment in your personal statement and skills section, in the job advert's words.
  • Scale. How many servers, VMs, users, sites? A 30-server, 200-user environment is a different job from 1,500 servers across 3 data centres. Managers use the numbers to place you at junior, mid or senior in seconds.
  • Evidence you kept things running. Uptime, backup success rate, restore tests, patch compliance, time to restore after an outage. Sysadmin work is invisible when it goes well, so make it visible with numbers.
  • Automation. A sysadmin who patches 140 servers by hand is a liability in 2026. PowerShell, Bash, Ansible or Intune on the CV, with a bullet that shows hours saved, moves you up the pile.
  • Certifications that match the stack. AZ-104 for an Azure shop, RHCSA for Linux, a VCP (now VCP-VVF or VCP-VCF Administrator) for VMware. Not because the cert proves skill, but because HR filters on it.

“The first thing I look for is whether they have run something my size. Number of servers, number of users, on-prem or cloud. Then I look for one bullet that shows they fixed something that was broken when they arrived. If both are there, they get a phone screen.”

Systems administrator CV skills: how to organise them

The skills section on a sysadmin CV is a lookup table for the recruiter and a truth test for the interviewer. Group by category so a recruiter finds "Active Directory" in one second, and list only what you can be quizzed on. Twenty to thirty items across six to eight categories is normal; this is one of the few jobs where a long skills list is expected.

Windows-focused sysadmin
Operating systems: Windows Server 2016/2019/2022, Windows 11 · Identity: Active Directory, Group Policy, Entra ID, Microsoft 365, Exchange Online · Virtualisation: Hyper-V, VMware vSphere · Cloud: Azure (VMs, Backup, Monitor) · Automation: PowerShell, Intune, SCCM/MECM · Backup: Veeam · Monitoring: PRTG, SolarWinds · Ticketing: ServiceNow
Linux-focused sysadmin
Operating systems: RHEL 8/9, Ubuntu Server 22.04, Rocky Linux · Automation: Bash, Python, Ansible, Terraform · Services: Nginx, Apache, Postfix, BIND, NFS, Samba · Containers: Docker, Podman, basic Kubernetes · Cloud: AWS (EC2, S3, IAM), Linode · Monitoring: Zabbix, Prometheus, Grafana, ELK · Security: SELinux, firewalld, fail2ban, CIS benchmarks, OpenSSL/PKI
Entry level (honest about depth)
Hands-on: Windows Server 2022 (home lab and placement), Active Directory, Windows 11 imaging, Microsoft 365 admin centre, ticketing (Freshdesk) · Working knowledge: Ubuntu Server, PowerShell, Bash, VMware Workstation, Hyper-V · Studying: Azure (AZ-104), RHCSA
  • Include version numbers. "Windows Server 2022" and "RHEL 9" tell a manager you are current; "Windows Server" alone could mean 2008.
  • Spell tools the way job adverts spell them: "Active Directory" not "AD" on first use, "Microsoft 365" not "O365". ATS keyword matching is often literal.
  • Soft skills (documentation, on-call reliability, explaining outages to non-technical staff) belong in bullets as evidence, not in the skills list.
  • No skill bars or star ratings. They do not parse and managers ignore them.

Sysadmin work experience bullets: weak to strong

The formula for a sysadmin bullet: the system, the scale, the tool, and a number that shows the result (uptime, hours saved, cost reduced, compliance raised). Six rewrites of the bullets most sysadmins actually write:

Weak (duty only)Strong (scale, tool, result)
Responsible for server administration and maintenance.Administer 85 Windows Server 2019/2022 and Ubuntu VMs on a 2-host Hyper-V cluster for 400 users; 99.9% uptime on file, print and ERP services over 18 months.
Performed patch management.Automated monthly Windows and Linux patching for 85 servers with PowerShell and Ansible, cutting patch weekend from 2 people for 10 hours to 1 person for 2 hours, with 97% compliance inside the 14-day window.
Managed Active Directory.Own Active Directory for 1,100 accounts across 4 OUs and 60 Group Policy objects; automated onboarding and offboarding with PowerShell and HR system exports, cutting account setup from 2 days to 20 minutes.
Handled backups.Rebuilt the backup schedule in Veeam for 120 VMs with an immutable Linux repository and monthly restore tests; job success rate rose from 89% to 99.6% and the annual DR test restored core systems in under 4 hours (target 8).
Migrated to the cloud.Moved 30 workloads (file, print, two line-of-business apps) from an end-of-life vSphere 6.7 cluster to Azure over 4 months; retired 3 hosts and a SAN, saving about £30,000 a year in hardware support and power.
Improved security.Applied CIS Level 1 hardening baselines to 85 servers, rolled out MFA to all 400 users, and closed 22 of 25 findings from an external vulnerability scan within one quarter, in time for Cyber Essentials Plus certification.
Where the numbers live: your monitoring tool for uptime, the backup console for success rates, Intune or WSUS for patch compliance, the ticketing system for volume and SLA, and finance for the hardware costs you retired.

Systems administrator personal statement examples (2 years, 5 years, senior, Linux)

Three lines: your title and years, the environment you run (platforms, scale), and one result with a number. One for each career stage below. Use a personal statement, not a career objective, unless you have no IT experience at all.

2 years' experience (junior sysadmin)
Systems administrator with 2 years supporting a 300-user Windows environment: 40 servers on Hyper-V, Active Directory, Microsoft 365 and Veeam backups. Scripted user onboarding in PowerShell, cutting setup time from 3 hours to 15 minutes, and maintained 99.8% uptime on file and print services. CompTIA Security+ and Network+.
5 years' experience (mid-level, hybrid)
Systems administrator with 5 years running hybrid Windows Server and RHEL environments (120 VMs on vSphere and Azure) for a 700-user healthcare group. Led the Exchange to Microsoft 365 migration for 700 mailboxes with zero data loss and automated patching with Ansible, raising compliance from 74% to 98%. AZ-104 and RHCSA certified.
Senior systems administrator
Senior systems administrator with 11 years, the last 4 as technical lead for a 3-person infrastructure team supporting 2,000 users across 12 sites (450 VMs, vSphere, Azure, Windows and Linux). Cut annual unplanned downtime from 31 hours to 6, led the migration of 200 workloads to Azure, and ran the DR programme that passed two external ISO 27001 audits.
Linux system administrator
Linux systems administrator with 6 years managing 300+ RHEL and Ubuntu servers for a SaaS company, on-premises and in AWS. Built the Ansible and Terraform automation that brought server provisioning from 2 days to 30 minutes, and the Prometheus and Grafana monitoring stack that cut mean time to detect from 40 to 3 minutes. RHCSA and AWS Certified CloudOps Engineer – Associate.

Sysadmin certifications: which ones count and how to list them

No certification is legally required to be a systems administrator in the UK, but many job adverts list one or two as required or preferred, and recruiters filter on them. Match the certification to the stack in the job advert:

  • Windows and Microsoft cloud: Microsoft Certified: Azure Administrator Associate (AZ-104) is the current standard. The old MCSA and MCSE certifications were retired in 2021; if you hold one, list it with the year, but do not expect it to open doors on its own. Microsoft 365 Certified: Administrator Expert (MS-102) helps for Microsoft 365-heavy roles.
  • Linux: Red Hat Certified System Administrator (RHCSA) is the one hiring managers trust most because it is a hands-on exam. CompTIA Linux+ and LPIC-1 are recognised but weigh less. Red Hat Certified Engineer (RHCE) for senior Linux and automation roles.
  • Virtualisation: VMware (Broadcom) VCP-VVF Administrator or VCP-VCF Administrator for vSphere-heavy shops. The older VCP-DCV exam has been retired, and Broadcom has reorganised the VMware certifications, so check the current names; if you hold a VCP-DCV, keep listing it with the year.
  • Cloud: AWS Certified CloudOps Engineer – Associate (formerly SysOps Administrator) or AWS Certified Solutions Architect – Associate for AWS environments; Google Associate Cloud Engineer for Google Cloud.
  • Foundational and security: CompTIA Network+, Security+ and Server+ help at junior level. For UK public-sector and defence work, security clearance (usually SC) matters more than any certificate; write "SC cleared" or "willing to undergo SC clearance". Cisco CCNA if you also touch switches and firewalls. ITIL 4 Foundation is often "preferred" at larger organisations and managed service providers.

List certifications in their own section under the personal statement or skills, with the full name, exam code and year earned. Renew or drop expired ones; interviewers check. A degree, HND or IT apprenticeship is typical, but plenty of good sysadmins have no degree and a stack of certs, and hiring managers know it.

Entry-level systems administrator CV (graduate, service desk to sysadmin)

Almost nobody is hired as a sysadmin with zero IT experience. The realistic path is 1st or 2nd line support or desktop support for 1 to 3 years, taking on server tasks, then moving up. Your CV has to show that you have already touched servers, even if your title never said so.

  • Pull the server work out of your service desk job and give it its own bullets: Active Directory account changes, Group Policy edits, patching, VM snapshots, backup checks. "Created 300 AD accounts and managed 20 GPOs" is sysadmin experience whatever your title.
  • Home lab counts, and IT managers respect it. Give it a short section: "Home lab: 6 VMs on Proxmox (Windows Server 2022 domain controller, Ubuntu web and file servers, pfSense firewall); patching automated with Ansible; documented in GitHub."
  • Certifications carry more weight here than at any later stage. Network+, Security+ and one of AZ-104 or RHCSA will get you screened in for junior sysadmin roles. List scheduled exams with the date.
  • Placements, apprenticeships and volunteer IT for a charity belong on the page with numbers (users supported, machines imaged, tickets closed). Split the skills list into hands-on, working knowledge and studying.
  • One page. No career objective about "seeking to grow"; write a short personal statement that names your lab, certifications and any support experience.
Do not list every technology you have watched a video about. A junior CV with Kubernetes, Terraform, Azure, AWS and Cisco all in the skills line reads as a wish list.

Format, length and ATS keywords for a systems administrator CV

Most mid-sized and large employers run applications through Workday, Oracle (Taleo), SAP SuccessFactors or Greenhouse, which parse the CV into fields before a person sees it. Sysadmins have long skills lists, and that is exactly what breaks in a two-column template.

  • Length: two pages is the UK norm for experienced sysadmins and infrastructure leads; one page is fine for graduates and juniors. Collapse jobs older than 10 years to one line each.
  • Single column, standard fonts, no icons, tables or text boxes. Section names the parser expects: Personal Statement (or Profile), Skills, Certifications, Experience, Education.
  • Skills as plain text lines grouped by category, as in the sample. Multi-column skill grids often parse as word soup.
  • Text-based PDF named Firstname-Lastname-CV.pdf unless the job advert asks for Word.
  • Keywords to mirror from the job advert, once each, same spelling: the exact OS versions, "Active Directory", "Group Policy", "Microsoft 365", "VMware vSphere" or "Hyper-V", "Azure" or "AWS", "PowerShell", "backup and disaster recovery", "patch management", "ITIL".
  • Mention on-call and out-of-hours maintenance windows if you have done them; many job adverts require it.
  • No photo, no date of birth, no marital status and no full street address (town or city is enough).

Before you apply, paste the job advert and your CV into the cvplex ATS checker. It shows which platform names are missing and which bullets have no number.

Frequently asked questions

How do I write a systems administrator CV?

Lead with a three-line personal statement that names your platforms (Windows Server, Linux, Active Directory, VMware, Azure or AWS), the scale you ran (servers, users, sites) and one result with a number. Follow with a categorised skills section, your certifications with exam codes and years, then experience bullets that each give the system, the scale, the tool and the result. Up to two pages; one is enough early in your career.

What skills should I put on a systems administrator CV?

Group them by category: operating systems with versions, directory and identity (Active Directory, Group Policy, Entra ID, Microsoft 365), virtualisation and cloud, scripting and automation (PowerShell, Bash, Ansible), backup and storage, networking basics, monitoring and ticketing tools, and security (patching, hardening, MFA). Twenty to thirty items is normal. List only what you can be interviewed on.

What certifications should a sysadmin have on a CV?

Match the stack: AZ-104 for Microsoft and Azure shops, RHCSA for Linux, VCP-VVF or VCP-VCF Administrator for VMware, AWS CloudOps Engineer – Associate for AWS. CompTIA Network+ and Security+ help at junior level. Write the full name, exam code and year. MCSA and MCSE were retired in 2021, so list them only as history.

How do I write a systems administrator CV with 2 years of experience?

Focus on scale and one or two improvements. State the size of the environment you supported (servers, users), the tools you used daily, and something you automated or fixed, with a number: onboarding time cut, patch compliance raised, a backup problem solved. Add your certifications and, if you have one, a home lab line. Keep it to one page.

Can I get a system administrator job with no experience?

Rarely straight in, but you can get a junior or service desk role with server exposure and move up in 1 to 3 years. Your CV should show a home lab with specific VMs and services, certifications (Network+, Security+, then AZ-104 or RHCSA), and any placement, apprenticeship, volunteer or university IT work with numbers. Be honest in the skills list about what is hands-on versus studied.

Systems administrator CV: personal statement or career objective?

Personal statement. An objective tells the employer what you want; a personal statement tells them what you have run. Even at entry level, a short profile that names your lab, certifications and any real support experience beats "seeking a challenging position". The only time an objective makes sense is a complete career change with no IT background at all.

Should a Linux systems administrator CV look different?

Same structure, different emphasis. Lead with distributions and versions (RHEL 9, Ubuntu 22.04), automation (Bash, Python, Ansible, Terraform), the services you ran and your monitoring stack. RHCSA carries real weight, and an active GitHub with your playbooks is worth linking.
