How to write a Resume Summary
Writing the optimal summary or objective section on a resume demands a clear understanding of personal strengths, professional intent, and the specific demands of the role you're applying to - in this case, a System Administrator. With clarity in these areas, you're well-positioned to create a summary that attracts attention, expresses your career aspirations, and increases your chances of landing an interview.
Significance of Summary/Objective Section
The importance of your resume's summary or objective section cannot be understated. It's the opening statement that sets the tone of your entire narrative. When a potential employer picks up a resume, the summary section likely makes the first impression. It's a quick snapshot of who you are professionally, your experience, what you have to offer, and your long-term career aspirations. Essentially, it's a 'movie trailer' for your resume, highlights reel of your key accomplishments and an articulation of your career objectives.
Crafting a Summary/Objective for a System Administrator
System Administrators are a crucial part of any company's IT team. They are responsible for overseeing, maintaining, and improving computer systems based on the specific needs of their employer. This is a highly technical role, but interpersonal skills are equally important, as the job often requires coordination between various teams.
When writing the summary/objective section, focus on your technical acumen, problem-solving prowess, capacity to work under pressure, and the outcomes of your efforts in previous roles. Highlight your proficiency with different systems and platforms, substantiated by specific achievements or certifications. But remember, It's equally important to demonstrate your ability to translate technical jargon into plain language for non-technical colleagues and stakeholders.
You should also express your career objective in clear terms. Why are you interested in this role? How does it fit into your long-term aspirations? What kind of work environment do you thrive in? Answers to these questions can provide a succinct statement of your career aspiration.
Also, as the technology domain is continually evolving, demonstrating a commitment to learning and keeping up-to-date with emerging technologies could add another attractive element to your resume.
Remember that the summary/objective should be concise, typically just 2-3 sentences. Furthermore, while the aim is to impress, try to stay away from buzzwords that don't communicate clear information about you.
Writing an effective summary/objective section on your resume is really about making sure you meet three key criteria: be interesting, be truthful, and keep it relevant to the role you want. Achieve this, and you will undoubtedly set the stage for the rest of your resume to shine.
Strong Summaries
- Results-driven Systems Administrator with 5 years of experience specializing in network topology design.
- Innovative Systems Administrator with a deep understanding of cloud network infrastructure with over 8 years of hands-on experience.
- Detail-oriented Systems Administrator with profound expertise in managing Unix/Linux environments and proficiency in scripting languages.
- Highly-skilled Systems Administrator, knowledgeable in Windows Server and Active Directory, with more than 10 years of professional experience.
- Energetic Systems Admin with 6 years of professional experience in cloud systems and Database management, especially in AWS and Oracle DB.
Why these are strong?
The above examples are good because they're specific, clear, and concise. Each summary starts by stating the professional's skills, like being results-driven, innovative, detail-oriented, highly-skilled, or energetic. They also provide explicit information about their skills, such as network topology design, cloud network infrastructure, Unix/Linux environments, or scripting languages. By listing their years of experience, the examples let potential employers see their longevity and reliability in the field. Also, mentioning specific software/tools like Windows Server, Active Directory, AWS, and Oracle DB shows their expertise in those areas, which may be crucial for certain roles based on the job description.
Weak Summaries
- As a System Administrator, I did a bunch of stuff. I fixed things. I help people.
- I'm a super awesome System Administrator - the best, really. I'm better than anyone else so hire me.
- Worked as system admin. Tasked with administrating systems.
- I am the one who have always been solving computer problems for friends and family.
Why these are weak?
The above examples are poor illustrations of a Professional Summary for a System Administrator's resume, primarily for three reasons.
Firstly, they lack specifics. It's critical to include concrete details about your professional experience and achievements in your resume summary. For example, 'fixing things' and 'administrating systems' are vague terms that don't clearly express your responsibilities or accomplishments in a way that's meaningful to potential employers.
Secondly, these summaries include unprofessional language. Statements like 'I'm a super awesome System Administrator - the best, really' may communicate confidence, but they also come across as arrogant and unprofessional. It's better to demonstrate your proficiency through specific examples of your work.
Finally, bringing an informal approach or personal history into a resume like 'I am the one who have always been solving computer problems for friends and family' is not recommended. It fails to provide a professional image.
A good professional summary should consist of a concise, polished overview of your skills, achievements, and career goals, using professional language and specific details that match the job description.
Showcase your Work Experience
Creating an impeccable work experience section for your System Administrator resume is not as daunting as you might think. A well-written Work Experience section provides potential employers with evidence of your technical and problem-solving abilities, showcasing that you're more than capable of upholding their networks and systems.
Structuring your Work Experience Section
When constructing this section, it's important to list your previous roles in reverse chronological order, starting with your most recent position. Include the job title, company name, location, and dates of employment. This basic information helps employers understand the progression of your career.
Clearly Detail your Job Activities and Achievements
Each role should have a brief, but explicit description of your responsibilities and achievements. While responsibilities paint a picture of your day-to-day tasks, including your achievements highlights how your work positively affected the organizations you've served. Be sure to focus on measurable accomplishments where possible.
Since you are a System Administrator, mention specific tasks such as setting up and maintaining computer systems, troubleshooting IT issues, and administrating network security. Pertinent achievements might include significant improvements in system efficiency, successful issue resolution, or positive changes in network security.
Quantify your achievements and impact using concrete numbers, metrics, and percentages to demonstrate the value you brought to your previous roles.
Tailor to the Job
Pay attention to the job description for the role you're applying and tailor your work experience section to match. Highlight experiences that align with the needs and responsibilities mentioned in the job advertisement.
Quantify where Possible
Quantifying your achievements helps provide a clearer context for your performance and impact. For instance, instead of saying you improved system efficiency, detail by how much exactly or mention the scope and scale of networks you've managed.
Use Action-oriented Language
Utilize action words to start each of your job responsibility and achievement bullets. Words like "led," "managed," "optimized," and "implemented" convey that you were active and impactful in your roles.
There you have it; a strong Work Experience section reconciles with the job description, details activities and achievements, and is clear, concise, and quantified where possible. Armed with these guiding principles, you're well on your way to creating an impressive narrative of your work history that reflects exactly why you're a great fit for that new System Administrator position.
Strong Experiences

- Implemented a new data back-up process that improved efficiency by 30%.
- Provided 24/7 support for critical infrastructure, leading to 98% uptime.
- Coordinated server upgrades, enhancing system performance by 20%.
- Lead the migration from on-premises servers to a cloud-based system, reducing costs by 15%.
Why these are strong?
These are good examples because each bullet point uses active verbs and quantifiable results, which shows the impact of each task. The points covered are also varied, showcasing a wide range of skills and applications, which may be more appealing to a potential employer. Furthermore, they are concrete and specific, leaving little room for misinterpretation about the job role.
Weak Experiences
- Installing, configuring, and trashing servers.
- Making laptops and computers work.
- Used computer stuff to fix things.
- Played around with the network.
- Prevented bad things from happening to the system.
Why these are weak?
The above examples are bad practices as they fail to define the specific roles which the system administrator did. They are vague and lack professionalism. They also fail to use the appropriate terminologies which reflect the job's demands. For example, 'Installing, configuring, and trashing servers' and 'Prevented bad things from happening to the system' are ambiguous and fail to detail what exactly the applicant did. Similarly, 'Played around with the network' is too casual for a resume. Furthermore, 'Making laptops and computers work' is too general and doesn’t indicate any specialized skills. Lastly, 'Used computer stuff to fix things' is not only too vague, it also lacks the formal tone expected in a resume.
Skills, Keywords & ATS Tips
Understanding the relevance of hard and soft skills on a System Administrator resume, plus the links between keywords, ATS and skill matching, can boost your chances of landing the job you're eyeing.
Hard and Soft Skills in a System Administrator Resume
In a System Administrator resume, both hard and soft skills play vital roles. Hard skills focus on technical know-how. These include solving technical issues, system security setup, and server management. Employers often list the hard skills they want in job postings.
Soft skills, on the other hand, showcase your ability to work within a team and an organisation overall. These include things like communication, teamwork, and problem-solving abilities. Although they can’t be measured like hard skills, they’re just as important.
A balanced mix of both hard and soft skills on your resume showcases your technical proficiency and your ability to fit into the company culture.
Connection Between Keywords, ATS and Skill Matching
Keywords, more specifically skill-related keywords, play a significant role in getting your resume noticed. Applicant Tracking Systems (ATS), which many companies use, scan resumes for these keywords to decide which ones to pass to human recruiters.
The ATS matches keywords from your resume with the ones in the job listing. This is why it's essential to include industry-specific hard and soft skills that align with those mentioned in the job advertisement.
So, to ensure that your resume garners attention, use the exact skills listed in the job post. Matching the language of the job posting improves the chance your resume will get past the ATS and be seen by a real person.
