System Administrator Resume: Choose a Format

The first step in writing a resume for a system administrator is to choose a format. The right format is critical to how your skills and experience are presented. Whether you’re an experienced professional or just starting out, there is a format that will put your qualifications in the best possible light.

There are three formats to consider for a system administrator resume: chronological, functional or combination. Each works a little differently, so let’s break it down!

Chronological resumes for system administrators

A chronological resume focuses on your work history. It lists your previous jobs in reverse order, starting with the most recent. This format is perfect for showing consistent career growth and highlighting your experience in IT or system administration.

The key advantage of this format is its ability to demonstrate career progression, which hiring managers appreciate. It’s also ATS-friendly, making it easier for your resume to pass initial screenings. However, if you have gaps in employment or are transitioning careers, this format might not be the best fit for you.

Functional resumes for system administrators

A functional resume emphasizes your skills and technical knowledge instead of your work history. It’s a good option if you’re new to system administration or have experience from other fields you want to showcase.

This format highlights your relevant skills, such as network management or cybersecurity, without tying them to your previous job titles. However, functional resumes are incompatible with most ATS and can raise questions about your career. That doesn’t mean a functional format can’t work for you, but it does have some limitations.

Combination resumes for system administrators

A combination resume merges elements of both formats by showcasing your skills first and then providing a detailed work history. This format is ideal for someone with impressive technical skills and at least some experience as a system administrator.

The combination format lets you spotlight specialized skills like cloud computing or virtualization while also demonstrating career growth. However, this format can make your resume longer than ideal. When using a combination format, focusing on the most relevant information to employers is critical.

Choosing a resume format

The right resume format highlights your strengths and ensures your qualifications stand out. If you’re unsure which is best, a chronological resume is always a good choice. It’s professional, easy to follow, and preferred by hiring managers. Plus, it’s ATS-friendly, which increases the likelihood of your resume passing the initial screening.

Even if you don’t have direct experience as a system administrator, you can still make a chronological format work for you. Focus on experiences that demonstrate your transferable skills. For example, if you’ve completed an internship, coursework or freelance IT projects, include those details in your resume. Describe how these experiences involved skills like troubleshooting, configuring software or collaborating to solve technical problems.

Also, tailor your resume to align with the job description. For instance, if a system administrator role emphasizes network management, highlight any experience working with network setups or learning network concepts in school. This tailored approach shows hiring managers that you’re capable, eager to learn and have the foundation for success in system administration.

How to Write a System Administrator Resume

Writing a resume for a system administrator role can feel overwhelming, but breaking it into sections makes the process easier. To get started, create a resume outline that includes the following sections:

• Contact Information
• Summary or Objective
• Work History
• Skills
• Education

This step-by-step resume-writing guide will help you make the most of each section. Then, we’ll explore additional sections to help you stand out from the competition. Let’s dive in!

Contact Information

Start by providing your contact information. This section should be simple and professional, as it’s the first thing hiring managers will see. Include your full name, city and state, phone number, email address and (optionally) your LinkedIn profile. Your contact information should look something like this:

Karen Smith
Seattle, WA
555-123-4567
karen.o.smith@email.com
linkedin.com/in/karensmith

Remember to check for typos. Even a small error could prevent hiring managers from reaching out to interview you.

Summary or objective

Next, you will write a brief introduction to your resume to grab the reader’s attention. You can choose either a resume summary or an objective statement based on your experience level.

A resume summary works best if you’re an experienced system administrator. It highlights your career achievements and tells employers why you’re the right fit. For example, a resume summary for a system administrator might say:

Dedicated system administrator with 10+ years of experience in network management, server maintenance, and cybersecurity. Successfully reduced downtime by 35% and led the implementation of cloud-based solutions for enhanced scalability.

On the other hand, an objective statement is ideal for entry-level professionals or career changers. It focuses on your skills, aspirations and enthusiasm for the job rather than past achievements. For example, an objective for a system administrator resume might say:

Motivated IT graduate with hands-on experience in network configuration and server administration. Eager to bring innovative solutions to ABC Company’s IT team.

No matter which type of introduction you choose, customize this section for each application. Include keywords from the job description to help your resume stand out to the ATS and show employers you are an excellent fit for the role.

Work history

The work history section is one of the most critical parts of your system administrator resume. Start by listing your previous jobs chronologically, starting with your most recent and working backward to create a clear career timeline. Each job entry should include your job title, employer’s name and location and the dates of employment. Then, beneath each job entry, write three to five bullet points highlighting your key achievements.

To make this section stand out, don’t just list job duties — focus on accomplishments that showcase your skills and the results you achieved. Hiring managers want to see how you contributed to the success of your team or organization.

Start each bullet point with a strong action verb like “configured,” “optimized” or “implemented.” Avoid vague phrases like “responsible for” and describe what you did and the results you achieved. Quantifying your accomplishments is also important. Use numbers, percentages or time frames to show the real impact of your work.

For example, instead of saying, “Maintained network systems,” you could say, “Managed a network of 200+ devices, ensuring 99.9% uptime by implementing proactive maintenance schedules.” This provides a clear picture of your contributions and expertise.

Additionally, tailor each bullet point to match the job description of the role you’re applying for. If the employer emphasizes cybersecurity, highlight any experience implementing security protocols or responding to threats.

Here’s an example of a well-written job entry on a system administrator resume:

System Administrator
Tech Solutions, Dallas, TX
2018 – Present

• Managed over 200 Linux and Windows servers, achieving 99.9% uptime through proactive monitoring and maintenance.
• Spearheaded the transition to cloud-based infrastructure, cutting operational costs by 20% and improving scalability.
• Implemented advanced security measures that reduced unauthorized access attempts by 40%.

Skills

The skills section of your system administrator resume is your chance to show hiring managers what you bring to the table. A well-rounded skills section should include both hard skills and soft skills, as employers look for candidates who are technically proficient and effective collaborators.

Hard skills are the technical abilities required to perform your job. Soft skills, on the other hand, focus on how well you work with others. By including both hard and soft skills on your resume, you provide a complete picture of your capabilities, making it easier for hiring managers to see your potential.

10 Tips for Writing a System Administrator Resume

1. Tailor your resume to the job description: Every system administrator role is different, so customize your resume for each application. Carefully read the job posting and highlight the skills and experiences the employer values most. For instance, if the role emphasizes network security, prioritize your cybersecurity certifications and experience managing firewalls or detecting threats.
2. Use action verbs: Start each bullet point in your work history with dynamic words like “configured,” “optimized” or “implemented.” These verbs convey a sense of achievement and action, which helps demonstrate your contributions. For example, don’t just say, “Set up backups.” Instead, say, “Implemented a new backup system that reduced recovery time by 50%.”
3. Quantify achievements: Numbers speak louder than words. Quantifying your accomplishments adds credibility and impact to your resume. For example, instead of “Maintained servers,” say, “Managed 200+ servers, achieving 99.9% uptime by implementing proactive maintenance schedules.” Using numbers and percentages helps hiring managers see the scale and value of your contributions.
4. Emphasize certifications: Certifications are a must-have in the IT field. List them prominently in a dedicated section to showcase your qualifications. For instance, certifications like CompTIA Security+ or AWS Certified Solutions Architect can immediately tell hiring managers you’re qualified for cloud or security-related tasks.
5. Include relevant projects: Showcase independent or team projects to highlight your technical skills in action. If you set up a home lab to test virtualization tools or contributed to an open-source project, include it. Briefly describe the project’s goal and your specific role, like “Designed a virtualized environment using VMware to replicate enterprise-level systems for troubleshooting scenarios.”
6. Optimize for ATS: Many companies use applicant tracking systems (ATS) to screen resumes. To pass this initial filter, include keywords from the job description, such as “network configuration,” “Linux,” or “cloud computing.” Also, use a well-organized format using standard headings like “Work History” and “Education.” Use a standard font and avoid overly creative formatting or graphics that an ATS might not process correctly.
7. Highlight technical and soft skills: A good system administrator isn’t just technically proficient — they also need strong soft skills. Balance your skills section by listing hard skills like database management alongside soft skills like communication and problem-solving. For example, you might explain how your ability to communicate helped a non-technical team adopt a new system smoothly.
8. Keep formatting clean: Choose a layout that’s easy to read and professional. Organize your content using consistent fonts, bullet points and headers. Leave some white space to avoid a cluttered look. This will help guide the reader’s eye and make your resume visually appealing.
9. Proofread thoroughly: Attention to detail is crucial in IT, and a single typo on your resume can send the wrong message. Proofread your resume multiple times or ask a friend to review it. Look for common mistakes like inconsistent formatting, misspellings or incorrect dates.
10. Use a professional template: A well-structured template can make all the difference. Choose one that emphasizes your technical skills and work history, with clear headings and sections. Avoid overly flashy designs. Hiring managers in IT value clarity and professionalism over creativity in formatting.
