Data and Systems Administration Resume: Choose a Format

Choosing a format for your resume as a data and systems administrator is essential to showcase your technical expertise and career history effectively. Whether you’re new to the field or have years of experience, the right format can help you highlight your strengths.

There are three main formats for your SysAdmin resume: chronological, functional, or combination.

Chronological Resumes for Data and Systems Administration

A chronological resume lists your job history in reverse chronological order, starting with your most recent role. This format is ideal if you have a solid data and systems administration history and want to show career progression.

The benefit of this format is its clarity, making it easy for hiring managers to see your relevant experience at a glance. It is also compatible with applicant tracking systems (ATS), which screen resumes before hiring managers review them. However, it may not be the best option if you have employment gaps or are switching careers.

Use This Example

Functional Resumes for Data and Systems Administration

A functional resume focuses on your skills rather than your job history. This format works best for someone new to data and systems administration from another field or with gaps in their work history. It lets you emphasize the technical skills that make you a strong candidate without tying them directly to job titles or a timeline.

However, the downside is that employers often prefer to see a clear job history. Also, functional resumes are incompatible with most ATS, which could hurt your chances of getting noticed.

Combination Resumes for Data and Systems Administration

A combination resume blends features of both the chronological and functional formats. This format starts with a skills section highlighting your technical expertise, followed by a detailed work history. This format works well to show your skills and work experience.

A flexible combination format allows you to tailor your resume to your strengths. However, it can be challenging to organize and could make your resume longer than ideal.

Choosing a Resume Format

When choosing a resume format, a chronological resume is often the safest bet for data and systems administrators. This format highlights your work history and professional growth, making it easy for hiring managers to see how your experience aligns with their needs.

What if you’re just starting or transitioning into a systems administrator role? In that case, you can still use a chronological format by focusing on how your past experiences, even in unrelated jobs, have prepared you for this role.

For instance, emphasize transferable skills from previous positions, like troubleshooting, managing technology, or handling large volumes of data. If you’ve worked in customer service, highlight how you managed technical issues or used problem-solving to assist customers. In roles that involve managing schedules or logistics, you can draw parallels to the organizational and planning skills required in systems administration. If you’ve worked with basic IT systems in any capacity, mention that experience to show your foundational knowledge.

Use job-specific keywords related to data and systems administration to make your resume ATS-friendly. Include industry terms like “network security,” “database management,” or “system troubleshooting.” Even if your experience isn’t directly related to systems administration, tailoring your job descriptions with relevant terminology will demonstrate your potential to employers.

How to Write a Data and Systems Administration Resume

Writing a resume for data and systems administration can be challenging, but it doesn’t have to be. Start by creating a resume outline that includes these key sections:

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

Once that critical information is covered, you can consider additional sections to enhance your resume. Each section of your resume should be tailored to highlight your expertise in maintaining and optimizing IT systems, databases and network infrastructure.

Here’s a step-by-step resume-writing guide to craft each section:

Contact Information

Start with the basics by providing your contact information. Include your full name, city and state, phone number, email address, and LinkedIn profile. You can also include a portfolio or website if it showcases relevant projects.

Summary or Objective

Your resume should start with a summary or an objective statement. Both options briefly introduce the hiring manager to who you are and why you’re a strong candidate.

A resume summary works best if you have experience in data and systems administration. It highlights your key skills and achievements in two to three concise sentences to grab the reader’s attention.

For example, a resume summary for a data and systems administration professional might say:

Detail-oriented systems administrator with 5+ years of experience managing complex databases, maintaining IT infrastructure and ensuring network security for mid-sized organizations. Proven track record of optimizing system performance and implementing security measures to reduce downtime.

However, an objective statement might be more appropriate if you’re new to the field. It shows your enthusiasm for the role and what you aim to achieve for the company.

For example, an objective statement for an aspiring systems administrator might say:

Recent graduate with a degree in information systems and a passion for data management and system optimization. Looking to leverage strong analytical and technical skills in a data and systems administration role.

No matter which you choose, customize this introduction for each job you apply to and use keywords that align with the job description. Tailoring your resume for each job application will help you stand out to the ATS and catch the eye of potential employers.

Work History

The work history section of your data and systems administration resume is your chance to showcase your experience and accomplishments. Start by listing your previous jobs chronologically, starting with your most recent position and working backward.

For each entry, include the job title, company name, location, and dates of employment. Then, write a few bullet points detailing your key responsibilities and achievements beneath each job.

To make your work history shine, start each bullet with strong action verbs like “spearheaded,” “managed,” or “created” to convey a proactive approach to work. Then, quantify your achievements whenever possible. For example, instead of saying, “Managed IT systems,” say, “Managed IT systems for a company with 500 employees, reducing downtime by 30% through proactive monitoring and system upgrades.”

Here’s an example of a job entry for a systems administrator’s resume:

Senior Data and Systems Administrator

10 Tips for Writing a Data and Systems Administration Resume

1. Tailor your resume to the job description: When applying for a data and systems administration role, customize your resume for each job listing. Employers often use specific keywords related to the skills and tools they need, such as “network security” or “database management.” Look at the job description closely, and weave those terms into your resume. This shows the employer that you have the exact skills they’re looking for, and it also helps your resume get past automated systems that scan for keywords.
2. Highlight technical skills: Your technical abilities should be front and center on your resume. As a data and systems administrator, employers expect you to manage databases, troubleshoot IT issues, and ensure network security. Whether it’s proficiency in SQL, experience with cloud platforms like AWS, or knowledge of network infrastructure, highlighting these abilities will demonstrate your expertise in handling complex systems.
3. Include measurable achievements: Don’t just tell employers what you’ve done—show them the impact of your work. Quantify your achievements whenever possible. For example, instead of saying you “maintained IT systems,” you could say you “reduced system downtime by 30% through proactive monitoring and timely upgrades.” Employers want to see how your work benefited the company, so including numbers or percentages gives them a clear idea of the value you brought to your previous roles.
4. Use action verbs: Strong verbs make your resume more dynamic and engaging. Instead of generic phrases like “responsible for,” use more impactful words like “managed,” “implemented,” or “optimized.” For example, you might say you “implemented new security protocols that reduced breaches by 40%.” These verbs help communicate that you’re proactive and results-driven, two qualities that are essential in data and systems administration.
5. Show continuous learning: Technology evolves fast, and employers want to know you’re keeping up with the latest trends and tools. Listing certifications like AWS or CompTIA Security+ on your resume shows you’re committed to continuous learning. Whether you’ve recently completed a relevant course or earned a new certification, include it to demonstrate that you stay current in the field and are constantly building your skill set.
6. Focus on problem-solving abilities: Data and systems administrators are often the go-to for troubleshooting issues. Highlight your problem-solving skills by providing examples of how you resolved technical problems in your previous roles. For instance, if you fixed a system outage that saved the company hours of downtime, include that story. Employers want to know you can step in when things go wrong and find solutions quickly.
7. Emphasize security skills: With cybersecurity being more crucial than ever, showcasing your knowledge of security protocols is necessary. Include that in your resume if you’ve worked with firewalls, VPNs, or encryption methods. Employers need to know that you can protect their systems from potential threats. If you’ve implemented specific security measures, highlight those to show you’re proactive in keeping networks safe.
8. Optimize for ATS: Many companies use applicant tracking systems (ATS) to filter resumes, so using the right keywords and formatting is essential. Include technical terms and skills mentioned in the job description — like “cloud computing,” “network administration\” or “troubleshooting” — to help ensure it passes through the ATS. Avoid using fancy fonts or graphics that might confuse the system, and stick to a clean, easy-to-read format.
9. Include relevant projects: If you’ve worked on specific IT projects that demonstrate your skills, consider adding a dedicated section to your resume. For example, if you helped migrate a company’s data to the cloud or implemented a new database system, you’ve applied your skills to real-world challenges. Including a projects section gives employers insight into how you’ve used your expertise in meaningful ways.
10. Keep it concise: While it’s tempting to include everything you’ve ever done, keeping your resume focused and relevant is important. Highlight essential skills and experiences that align with the data and systems administration role. Employers typically scan resumes, so keeping yours clear and to the point will make it easier for them to see why you’re a strong candidate.
