Linux systems administrator resume examples from 2025

Put a resume summary on the top of your resume to highlight your accomplishments. A resume summary sums up your experience and skills, making it easy for hiring managers to understand your qualifications at a glance. Here are some tips to write a strong, impressive resume summary:

Step 1: Mention your current job title or the role you're pursuing.

Step 2: Include your years of experience in linux systems administrator-related roles. Consider adding relevant company and industry experience as relevant to the job listing.

Step 3: Highlight your greatest accomplishments. Here is your chance to make sure your biggest wins aren't buried in your resume.

Step 4: Again, keep it short. Your goal is to summarize your experience and highlight your accomplishments, not write a paragraph.

These four steps should give you a strong elevator pitch and land you some linux systems administrator interviews.

Your Skills section is a place to list all relevant skills and abilities. Here is how to make the most of your skills section and make sure you have the right keywords:

1. Look to the job listing. You often need to include the exact keywords from the job description. Take note of the skills listed for the job.
2. Put all relevant hard and soft skills in your skills section.
3. Be specific. If you are too broad, you may not be giving the best picture of your skills and leave the hiring manager uncertain of your abilities.
4. Be up to date. Software names change and companies merge. Don't look out of touch by being careless.
5. Be accurate. Spelling and even upper or lowercase can dramatically change meanings. Make sure you are correctly listing your skills.

These five steps should give you a strong elevator pitch and land you some linux systems administrator interviews.

Your work experience should be structured:

1. With your most recent roles first, followed by earlier roles in reverse chronological order.
2. Job title, along with company name and location on the left.
3. Put the corresponding dates of employment on the left side.
4. Keep only relevant jobs on your work experience.

Your resume is not a list of responsibilities or a job description. Instead, it is your chance to show your accomplishments and show why you're good at what you do.

• Use the What, How, and Why format. Answering these questions turns a bland job description into an effective showcase of your abilities.
• What were your responsibilities or goals?
• How did you accomplish them?
• Why were your results important? (How did it impact your company? Can you quantify the results in numbers? )

Here are examples from great linux systems administrator resumes:

The education section should display your highest degree first.

Place your education section appropriately on your resume. If you graduated over 5 years ago, this section should be at the bottom of your resume. If you just graduated and lack relevant work experience, the education section should go to the top.

If you have a bachelor's or master's degree, do not list your high school education. If your graduation year is more than 15-20 years ago, it's better not to include dates in this section.
