Did anything ever come straight out of the box and work right the first time? Sometimes. An expert like you can tweak it to get the maximum performance. Just like you know Cisco and Linux, we know CVs.

Use this CV format cfg:

System Administrator CV Format

  • The reverse-chronological CV format will bring your most relevant experience to the top. 
  • Use CV fonts like Calibri or Garamond in 10–12pt.
  • Set 1-inch CV margins, and use white space to guide their eyes. 
  • The one-page CV is probably best. If you have sizable experience and are applying to a specialist position, feel free to extend your CV length
  • Order your CV sections like this: CV Header, Objective, Experience, Education, and “Additional.”
  • Send your CV as a PDF, unless instructed to otherwise.
  • Use a modern CV template unless you’re applying to a traditional company.

We’re ready to boot.

2. Write a Fibre Optic System Administrator CV Summary

Your CV profile must be as smooth and fast as a fibre optic connexion. Get the right information through, right away. There is no time to waste. According to the Ladders Eye Tracking Study, employers only spend an average 7.4 seconds scanning a CV.

After you are finished writing your system admin CV, scan it through a few times, and think which pieces of information you’d like to transmit in 7.4 seconds. Then scan the job posting, and think about what they’d like to know you can do by the time 7.4 seconds are up.

Summarise your best achievements with relation to the above, back them up with numbers, and write a 1Gbps CV summary.

System Administrator Professional Summary

Good Example
A cost-saving system administrator with 4+ years of experience, and a proven track record in supporting 1,500 users across 4,000 stationary and mobile devices at NeoCorp Jersey. Reduced tickets and ticket response time by 37% and 50% respectively. Improved server uptime from 97% to 99.9%. Seeking to leverage the optimization and saving skills in a new position at T&G.
Bad Example
I am a system administrator with 4 years of experience of managing the IT infrastructure of NeoCorp Jersey, including desktops and mobile devices. Handle all day-to-day IT operations, user tickets, and cybersecurity. Able to start immediately.

Don’t waste packets. Be scarce with words also, sum up the significance of your achievements, but if you need to explain them, do it in your job description. 

But what if you’re writing an entry-level system administrator CV? Think internships, volunteering, and school achievements. Here’s an example of a junior system administrator CV.

Good Example
Motivated system administrator looking to boost ROI at CrocLabs Inc. Have worked as a volunteer sys admin at local homeless shelters for the last 2 years. Completed work under budget for both time and cost.
Bad Example
Entry-level network administrator with no professional work experience so far. Seeking a new job with room for advancement.

Expert Hint: To make sure you do not sound generic, considering writing a targeted CV, and referencing your future employer in the CV profile.

3. Patch Your System Administrator CV Job Description To the Newest Version

The CV work experience section is where you score the points. You have their attention. Demonstrate that you are as perfect as Linux for this job. Focus on the requirements of the job, if it’s a Windows system admin CV, focus on your Windows experience, and vice versa.

Back up your performance with solid numbers to show exactly the kind of impact you can make on their business. Be the Disc Defragmenter they need.

Here’s how:

4. Buffer Your Education Section Without Glitches

The length of the education section on your CV will depend on the size of your experience. If you have terabytes of relevant experience, you can cut down and just list the school name and major. 

If you have relatively little experience, list your GPA, you can expand this section with relevant coursework or achievements sections. Focus on the aspects that fit the profile of your new position.
