Dear Hiring Manager,

I have followed your company's remarkable journey in pioneering technological solutions and am impressed by your commitment to innovation and excellence. As an experienced Senior System Administrator with a solid background in Linux and Cloud Solutions, I understand the significant role that robust and efficient system administration plays in the success of a tech-focused enterprise.

In my recent role at IBM, I spearheaded a critical project that involved the migration of 60% of our servers to a Cloud-based solution. This initiative not only enhanced our infrastructure's scalability but also resulted in a more cost-effective and resilient ecosystem for our server needs. Notably, I led a team that meticulously planned and executed the migration process, reducing potential downtime risks and subsequently decreasing overall downtime by an impressive 15%. I believe this experience, coupled with my ability to manage server installations and implement custom script solutions, showcases my proficiency in delivering on key company objectives.

I am particularly attracted to the opportunity at your organization due to its reputation for fostering professional development and embracing cutting-edge technologies. I am keen to bring my technical acumen and problem-solving expertise to your team, contributing to your mission of driving industry innovation. I am confident that my proactive approach to system administration and my track record of improving system uptime significantly will be beneficial for your company.

I look forward to the possibility of discussing with you how my skills and experiences align with the goals of your organization. Please feel free to contact me to arrange a meeting at your earliest convenience. Thank you for considering my application.

Sincerely,

TIMOTHY DUNCAN

What should your linux system administrator cover letter look like - formatting and organizing your information

Have you ever wondered what are the must-have sections you need to include in your linux system administrator cover letter? Our builder sets those up for you with:

Kick off your linux system administrator cover letter: the salutation or greeting

When writing your linux system administrator cover letter, remember that you're not writing for some complex AI or robot, but for actual human beings.

And recruiters, while on the lookout to understand your experience, would enjoy seeing a cover letter that is tailored to the role and addresses them. Personally.

So, if you haven't done so, invest some time in finding out who's the hiring manager for the role you're applying to. A good place to start would be LinkedIn and the corporate website.

Alternatively, you could also get in touch with the company to find out more information about the role and the name of the recruiter.

If you haven't met the hiring manager, yet, your linux system administrator cover letter salutation should be on a last-name basis (e.g. "Dear Mr. Donaldson" or "Dear Ms. Estephan").

A good old, "Dear HR Professional" (or something along those lines) could work as your last resort if you're struggling to find out the recruiter's name.

The linux system administrator cover letter introduction: focusing on your unique value, with a creative twist

You are not the only one wondering how to start your linux system administrator cover letter. Those first two sentences introduce your profile and should be memorable.

No pressure.

When beginning your linux system administrator cover letter, immediately point out the unique value of working with you. In other words, what you promise to bring to the role by using your past track record of success.

Start your linux system administrator cover letter with a creative twist by telling a joke or stating something relatable. Select this type of introduction only if it aligns with the company culture.

How to select your best achievement for the middle, or the linux system administrator cover letter body

You probably feel exhausted by this point in your application: you've dived into all the details of your success and skills in your linux system administrator resume.

What else can you include in your linux system administrator cover letter body?

Well, for starters, the next three to six paragraphs should show you further value as a professional. Or, why should recruiters choose you?

Think back on a noteworthy achievement that answers key job requirements and dive deep.

Structure your linux system administrator cover letter middle as you'd a story: following chronological logic and highlighting outcomes, thanks to skills.

At the end of the day, you'd want recruiters to be able to see you as the best candidate for the role and understand more about who you are and what makes your success unique (and valuable to the role).

Body Paragraph
At my previous role at TechCorp, I successfully migrated 30+ servers from an outdated legacy system to a robust cloud infrastructure within a strict 3-month deadline, achieving a 25% cost reduction while enhancing system availability by 99.9%. My adeptness at automation using Ansible reduced deployment time by 40%, exemplifying my commitment to efficiency and reliability in mission-critical environments.

Final words: writing your linux system administrator cover letter closing paragraph

The final paragraph of your linux system administrator cover letter allows you that one final chance to make a great first impression.

Instead of going straight to the "sincerely yours" ending, you can back up your skills with a promise of:

  • how you see yourself growing into the role;
  • the unique skills you'd bring to the organization.

Whatever you choose, always be specific (and remember to uphold your promise, once you land the role).

If this option doesn't seem that appealing to you, close off your linux system administrator cover letter with a follow-up request.

You could even provide your availability for interviews so that the recruiters would be able to easily arrange your first meeting.

Closing Paragraph
I am eager to bring my expertise to your team. Please contact me to arrange an interview at your earliest convenience.
RIGHT

No experience linux system administrator cover letter: making the most out of your profile

Candidates who happen to have no professional experience use their linux system administrator cover letter to stand out.

Instead of focusing on a professional achievement, aim to quantify all the relevant, transferrable skills from your life experience.

Once again, the best practice to do so would be to select an accomplishment - from your whole career history.

Another option would be to plan out your career goals and objectives: how do you see yourself growing, as a professional, in the next five years, thanks to this opportunity?

Be precise and concise about your dreams, and align them with the company vision.
