Houston, Texas


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.

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.

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.

  • 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.
