What does a system administrator do?

The inconspicuous presence of system administrators should make us all the more grateful for the countless automated things in our lives we take for granted. For any organization to operate without computer networks is unthinkable, but those systems don’t run completely on their own. 

System administrators are responsible for ensuring the day-to-day functions of computer networks are failsafe, and for troubleshooting unforeseen glitches. Their expertise enables them to organize, install, and support system components such as local area networks (LANs), wide area networks (WANs), network segments and data communication systems.

Statistical insight

The Bureau of Labor Statistics in the U.S. projects employment growth for network and computer systems administrators of 5% from 2020 to 2030. Although overall demand for information technology workers remains robust, the trend toward cloud-based systems means fewer system administrators are needed in workplaces.

How to write a system administrator resume

You’ll seldom go wrong following these two simple rules for any resume.

  1. Don’t exceed one page.
  2. Include these resume sections:
  • Header
  • Summary
  • Employment history
  • Education
  • Skills

To better the chances of your system administrator resume hitting the mark, there’s one more ground rule: customize a different version for each specific job application. 

  • Convincing the employer or client that you are the best job match is about speaking directly to what is required and expected. Make sure you know exactly what that is by carefully reviewing the posted job description and researching all other avenues.
  • Optimizing your resume with adequate keywords will help ensure it passes through the applicant tracking systems (ATS) that many hiring organizations use to screen online document submissions.

Choosing the best resume format for a system administrator

The best format for structuring your system administrator resume will depend on the career path you’re following. If you’ve worked mostly in employee positions and have your sights set on another one, the most commonly used chronological format is a good choice. 

A functional resume format may be suitable for system administrators who have worked independently in consulting roles. It allows you to highlight your qualifications from the perspective of projects, clients or transferable skills. Hybrid (combination) resume formats are another versatile option, incorporating both chronological and functional elements. 

Expert tip

Don’t overlook the header

A striking resume header will get your system administrator job application noticed for the right reasons, especially if the same visual style applies to your cover letter so the two documents match. An eye-appealing header design distinguishes you from other candidates and displays your contact information prominently for recruiters to easily get in touch.

Resume summary example

An attention-grabbing resume summary, sometimes called profile or personal statement, is your direct and immediate connection with recruiters. In as few concise and precise words as possible —including ATS-beating keywords — it’s a synopsis of who you are, what you’ve accomplished and why you’re an ideal fit for this job and employer. It’s also the place where you can, and absolutely should, express hints of your personality, passion and purpose.

Here is a resume example summary that senior system administrators can customize.

Employment history sample

The more work experience you have, the more selective you need to be in determining which of your most relevant and desirable accomplishments to list in the employment history section.

Your work history descriptions should be framed as achievements, rather than job titles and duties. Help employers or clients to envision your past contributions being replicated for them in the future. Include facts and figures to quantify savings, efficiencies and any other measurable outcomes to your credit.

Below is a system administrator employment history resume sample you can adapt.

CV skills example

For each customized version of your CV, be very selective about the mix of skills that seem most likely to gain you a winning edge over other system administrators. Never squander the opportunity by being too vague or generic. Being more precise and adding a unique context could make a crucial difference. Remember that your hard skills — notably computer expertise — will not only be shared by other candidates but also expected by recruiters. 

Also, be sure to include some soft skills to give a sense of your attitude, habits and how well you get along with others. Your competitors might not emphasize or even mention their people skills.

Check out the skills section from our system administrator resume sample below.

Resume layout and design

Fancy or flashy is never a good look for any resume, but flawless always is. Keep the layout and design simple, for a document that appears user-friendly at arm’s length. From font styles to margin widths, your formatting choices should be consistent with a sleek, streamlined and uncomplicated result. 

But that need not be synonymous with plain and boring. Eye-appeal can be achieved without sacrificing simplicity. Inviting and easy to read should be your overriding visual consideration.

Expert tip

If graphic design programs aren’t exactly in your wheelhouse, you may consider using a professionally-designed resume template to keep your formatting clean and customizable.

Key takeaways for a system administrator resume

  1. All of your resume content and wording should be tailored to what the hiring organization needs and values. Incorporating enough keywords is an ATS-proof safeguard.
  2. Limited page space dictates that only your most directly relevant qualifications be highlighted in each resume section.
  3. Don’t overlook the importance of people skills in a system administrator role, since your technical expertise alone may not be enough to set you apart.
