System Administrator cover letter example


Kansas City, KS


Dear Hiring Manager,

With a solid background in network administration and hands-on experience in maintaining robust Cisco systems across retail and warehouse environments, I am eager to bring my expertise to your team. While my resume outlines the breadth of my technical skills, it is my strategic improvements in network management that I believe will be most beneficial for your organization.

At Best Buy, I spearheaded the implementation of a new inventory management system that culminated in annual cost savings of $100,000. This initiative not only optimized operations but also showcased my ability to manage complex projects with a direct impact on the bottom line. My tenure with FedEx, where I was instrumental in maintaining 24/7 network connectivity for 40 branch offices, further underscores my capacity to support enterprise-level network infrastructures under demanding conditions.

I am keen to discuss how my strategic vision and robust technical skills can contribute to the success of your team. I welcome the opportunity for an interview at your earliest convenience and look forward to exploring how we can collaborate.

The system administrator cover letter salutation: how to address hiring managers

After covering the format of your system administrator cover letter, let's look at the salutation.

Back in the day, the cordial "To whom it may concern" or "Dear Sir/Madam", might have worked out fine.

But, nowadays, your cover letter should approach hiring managers on a more personal basis.

So, what to do about your cover letter salutation?

If you've messaged the recruiters and are on a first name basis or a more formal one, use the hiring manager's name in the greeting (e.g. "Dear Sophie," "Dear Ms. Givens", or "Dear Mr. Everett,").

Always aim to make the effort to find out the name of the hiring manager, who'd be assessing your application. Search on LinkedIn, double-check the advert on the corporate website, or message the brand on social media to find out more about the role.

If you can't find the hiring manager's name (and still want to sound professional), use "Dear HR Team,", "Dear Hiring Manager,", or the likes.

List of salutations you can use

  • Dear Hiring Manager,
  • Dear [Company Name] Team,
  • Dear [Department] Manager,
  • Dear Mr./Ms. [Last Name],
  • Dear Dr. [Last Name],
  • Dear [Job Title] Search Committee,

Your system administrator cover letter intro: showing your interest in the role

On to the actual content of your system administrator cover letter and the introductory paragraph.

The intro should be no more than two sentences long and presents you in the best light possible.

Use your system administrator cover letter introduction to prove exactly what interests you in the role or organization. Is it the:

  • Company culture;
  • Growth opportunities;
  • Projects and awards the team worked on/won in the past year;
  • Specific technologies the department uses.

When writing your system administrator cover letter intro, be precise and sound enthusiastic about the role.

Your introduction should hint to recruiters that you're excited about the opportunity and that you possess an array of soft skills, e.g. motivation, determination, work ethic, etc.

Intro Paragraph
Diving into the innovative network solutions that [Company Name] has pioneered, I'm captivated by the synergy between your technological ambitions and my systematic approach to IT infrastructure management. My tenure in system administration aligns seamlessly with the cutting-edge and user-centric environment that defines your company's backbone.

Structuring your system administrator cover letter body to add more value

You've hinted at your value as a professional (this may be your passion for the job or interest in the company) in your introduction.

Next, it's time to pan out the body or middle of your system administrator cover letter.

When creating your resume, you've probably gone over the advert a million times to select the most relevant skills.

Well, it's time to repeat this activity. Or just copy and paste your previous list of job-crucial requirements.

Then, select one of your past accomplishments, which is relevant and would impress hiring managers.

Write between three and six paragraphs to focus on the value your professional achievement would bring to your potential, new organization.

Tell a story around your success that ultimately shows off your real value as a professional.

Body Paragraph
At my previous role, I spearheaded the migration of our on-premises infrastructure to a cloud-based solution, consolidating resources and achieving a 30% reduction in operational costs. This complex project involved coordinating a team of five to ensure a seamless transition with zero downtime for our services, showcasing my project management and technical skills in cloud computing.

A sincere and original way to end your system administrator cover letter

When writing their system administrator cover letter, candidates tend to use one of these phrases, "Sincerely yours" or "I look forward to hearing from you".

Both statements show good manners, but your cover letter should end in a more actionable manner.

Write about:

  • how you see yourself growing in the role/organization;
  • the benefits you would bring about (you'd impress even more with tangible metrics);
  • the next steps in the process (provide your availability for interviews).
Closing Paragraph
I am eager to bring my expertise to your team and discuss how I can contribute to your goals. Please reach out to arrange an interview at your earliest convenience.

What to write on your system administrator cover letter, when you have zero experience

The best advice for candidates, writing their system administrator cover letters with no experience, is this - be honest.

If you have no past professional roles in your portfolio, focus recruiters' attention on your strengths - like your unique, transferrable skill set (gained as a result of your whole life), backed up by one key achievement.

Or, maybe you dream big and have huge motivation to join the company. Use your system administrator cover letter to describe your career ambition - that one that keeps you up at night, dreaming about your future.

Finally, always ensure you've answered why employers should hire precisely you and how your skills would benefit their organization.

Key takeaways

Creating your system administrator cover letter should be a personalized experience for the role and the recruiter, where you:

  • Format your cover letter using the same ATS-friendly font (e.g. Railway) as you did for your resume;
  • Greet recruiters, using their name, and follow up with two sentences to introduce yourself, your interest in the role, and to stand out;
  • Map out one key success from your career (or life) that has taught you job-crucial skills;
  • Substitute your lack of experience with an achievement from your internships, degrees, or volunteering gigs;
  • End with a promise for your potential or your availability for an interview.
