Systems Administrator CV: example, skills and writing tips

Systems administrator CV example

The CV below shows the level of detail recruiters look for: the size of the infrastructure, the technologies, your level of responsibility, projects and results.

Every line says what was administered, at what scale, with which tool and with what result. The rest of this guide shows how to build each section in the same way.

Job title and professional summary

Choose a title that reflects your actual role

Infrastructure titles vary a lot between companies. Keep the real titles of your past roles and use your CV title to make your main environment obvious.

Systems Administrator – Windows / VMware
Linux Systems Administrator
Systems Administrator – Microsoft 365 / Azure, hybrid environment

Systems Administrator – Windows / VMware is more informative than IT Administrator if your specialism is clearly Microsoft and virtualisation.

Professional summary examples

Windows and virtualisation

Systems administrator with 6 years’ experience on Windows Server and VMware. Active Directory, Group Policy, backups, monitoring, patch management and level 2/3 support on an infrastructure of more than 250 servers.

Linux

Linux systems administrator with 5 years’ production experience. Server administration, Bash scripting, automation, monitoring, incident management and support for business-critical applications.

Junior systems administrator

Junior systems administrator with a two-year work-study placement: Active Directory accounts and groups, Windows Server support, VM creation in VMware, backup monitoring and PowerShell scripts for routine tasks.

Avoid summaries such as “IT enthusiast, autonomous and versatile”: they say nothing about your technical level.

Systems administrator skills by area

Bring forward your core stack and prove it in your experience. The third column shows how to turn each skill into a CV line.

Technologies: show your real level

• Give context, not ratings: “administration of a VMware environment hosting 200 VMs” says far more than “VMware: expert”.
• Versions and distributions: add them when they matter for the posting (for example Debian, Ubuntu, Red Hat or Rocky Linux), without stacking keywords.
• Monitoring tools: name the ones you use (Centreon, Zabbix, Nagios, PRTG, Dynatrace…) and what you monitor.
• Ansible, Terraform, Docker, Kubernetes: state your actual level, for example “modified and ran existing Terraform configurations” versus “wrote Terraform modules”. Docker experience is not Kubernetes experience.
• Cloud: list the services and operations you actually handle rather than ten service names.
• Certifications (Microsoft, Linux, cloud): list only those you hold, with their exact official title.

Experience and achievements

A simple structure for each line

Describe your work in this order: context → your own action → technology or method → scale → result. Make your level clear: operating, administering and designing are different responsibilities.

Too vague

Windows Server migration.

Informative

Took part in the migration of [X] servers to a newer Windows Server version: dependency inventory, build of new servers, service migration, tests with application teams and decommissioning after validation.

Achievement examples to adapt

Replace [X] and [Y] with your own figures, and keep only those you can rely on:

• Administered [X] servers and [X] user accounts across [N] sites.
• Automated account creation in PowerShell, cutting processing time from [X] to [Y] minutes per request.
• Migrated [X] servers to a new platform with no unplanned downtime outside maintenance windows.
• Analysed recurring incidents on a service, corrected its configuration and added an automatic check; related incidents fell by [X]%.
• Kept patch compliance above [X]% on the servers in scope.
• Contributed to availability above [X]% on the services in scope.
• Created an internal knowledge base of recurring incidents and their resolution.

Availability depends on several teams: “contributed to” is the honest wording. A backup is only useful if it can be restored, so restore tests are worth mentioning.

Education and qualifications

Systems administrators come from IT, systems and networks, telecommunications or computer science courses, engineering schools and technical certifications. Use the format degree – specialism – institution – year:

[Degree] – [specialism]
[Institution] — [year]

• Certifications: list them if you hold them, they are relevant and recent enough to add value, with their exact official title.
• Experienced administrators: recent hands-on experience usually carries more weight than education.

ATS readability and tailoring

Make your CV easy to read for ATS and recruiters

Employers and IT services companies often search applications by technical environment. The aim is not to “beat” software, but to make your stack easy to identify:

• use standard headings: Professional summary, Technical environment, Key figures, Experience, Education, Certifications;
• keep a readable layout with real text, without skill bars or logos replacing the names of technologies;
• use the terms that match your work: systems administrator, Windows Server, Linux, Active Directory, VMware, Microsoft 365, Azure or AWS, backup, PowerShell, Bash, monitoring, patching, level 2/3 support.

Systems Administrator – Windows / VMware – 300 servers – PowerShell – Azure is far clearer than Versatile IT administrator when the posting is for infrastructure expertise.

Tailor your CV to each job

Adjust your title, summary, highlighted stack, projects and certifications to the posting, without inventing a skill.

Junior systems administrator or career change

With little professional experience, be precise about what you have actually done:

• Internships and work-study placements: describe them like real jobs, with the systems, tickets and tools involved.
• Home lab: a lab can show initiative (a small domain, VMs, scripts), as long as it is clearly labelled as a personal lab.
• From IT support: bring forward server, directory and backup tasks you already handle, and your scripting.
• Towards systems engineer or DevOps: gradually show design work, projects, automation and infrastructure as code, without changing past titles.

Trained or working in France?

If your IT background is French, a few adjustments make your CV clearer to English-speaking recruiters.

French qualifications

Keep the French name and add a short explanation, without claiming an equivalence with British, American or other qualifications:

• BTS SIO (services informatiques aux organisations): a French two-year higher vocational diploma in IT services for organisations.
• BTS CIEL (cybersécurité, informatique et réseaux, électronique): a French two-year higher vocational diploma covering cybersecurity, IT, networks and electronics.
• BUT Réseaux et télécommunications or BUT Informatique: French three-year university technology degrees.
• Licence: a French three-year university degree; give its field, for example systems and networks.

BTS SIO – [option] (French two-year higher vocational diploma in IT services)
[School] — [year]

French job titles and terms

Translate the work, not the words. An “administrateur systèmes” is a systems administrator; an “ESN” (entreprise de services du numérique) is an IT services company or consultancy; “astreinte” is on-call; “exploitation” is IT operations; “MCO” is keeping systems in working order (run or operational maintenance); a “PRA” is a disaster recovery plan and a “PCA” a business continuity plan.

Mistakes to avoid and final checklist

Listing too many technologies without context

Show which ones you actually administer.

Leaving out the size of the infrastructure

Servers, users, VMs and sites give recruiters essential context.

Claiming cloud expertise after occasional use

Name the services and operations you actually handle.

Confusing operations and administration

Explain your level of responsibility.

Forgetting projects and results

Migrations, automation, fewer incidents and time saved make a strong CV.

Calling yourself DevOps without the scope

Keep your title aligned with your real experience and show your automation skills.

Ignoring security

Patching, access and vulnerabilities are part of modern system administration.

Checklist before you apply

• The title names your main environment.
• Key figures show the scale (servers, users, VMs, sites).
• Each role states your level: operations, administration, projects or design.
• Technologies are described by their use; certifications have their exact title.
• At least one automation, project or incident result is quantified honestly.
• The layout is readable and technologies are written as text.
• The CV has been adjusted to the posting.

CVReader sample: systems administrator CVs and job postings in France

In the extraction of 13 October 2026, CVReader identified 128 systems administrator profiles among recently analysed CVs, and 205 systems administrator postings among recent France Travail postings. This is a French sample, not a measure of the UK, US or global market.

How to read these figures

• CVs: profiles analysed by CVReader in the 3 months before the extraction.
• Postings: France Travail postings from the 30 days before the extraction.
• The periods differ on purpose: a CV from a few weeks or months ago can still be used to apply to a recently published posting.
• These figures do not describe all candidates or all vacancies in France. They should not be read as a number of postings per candidate, a shortage, a level of competition or a likelihood of being hired.

CVReader methodology. Aggregated data. Each CV is assigned to a single occupation, based on the match estimated by CVReader; only profiles with a sufficient match are included in the figures shown. Figures come from an extraction supplied to CVReader and are not updated in real time. Extraction date: 13 October 2026. CVs: profiles analysed in the 3 months before the extraction. Postings: France Travail, in the 30 days before the extraction. Occupation: ROME M1801 – Administrateur / Administratrice de systèmes d'information (ROME is the French public employment service’s occupation classification).

Systems administrator CV: frequently asked questions

Which skills should I put on a systems administrator CV?

Prioritise the systems you actually administer, Active Directory, virtualisation, backups, cloud, scripting, monitoring and security, as far as they match your experience.

Should I mention both Windows and Linux?

Yes, if you administer both. Describe your responsibilities rather than simply naming them.

Which figures should I include?

The number of servers, virtual machines, users, sites and migrations shows the size of your environment.

Should I mention PowerShell?

Yes, if you use it to automate tasks. Ideally, describe one or two concrete automations and the time they saved.

How do I move towards a systems engineer or DevOps role?

Gradually show projects, automation, infrastructure as code, design work and wider technical responsibilities, without changing your past titles.

Is a CV the same as a resume?

In the United States and Canada, the document used to apply for most jobs is usually called a resume; in the UK and many other countries it is called a CV. The advice in this guide applies to both.
