Michelle Sanders

Houston, Texas


Dear Hiring Manager,

I have followed your company's innovative approaches to optimizing system performance and infrastructure with keen interest, recognizing the alignment with my professional experience, particularly in Linux systems and robust networking practices.

During my tenure at Dell, I spearheaded the deployment and management of a network of 50 servers, achieving a significant 30% reduction in system downtime. This involved not only implementing rigorous monitoring protocols but also leading the meticulous migration of DNS infrastructure to Bind9, thereby elevating system reliability and performance. Such initiatives underscore my commitment to technical excellence and have a direct impact on maintaining operational continuity.

I am eager for the opportunity to discuss how my background, skills, and certifications align with the needs of your team. Your focus on fostering continuous improvement within the system administration domain resonates with my own professional philosophy and achievements, and I am looking forward to contributing to your company's success.

How to personalize your junior system administrator cover letter greeting

Before you start writing your junior system administrator cover letter, take the time to find out who is recruiting for the role.

Search for the recruiter's name on LinkedIn or the corporate website to address them personally in your junior system administrator cover letter salutation.

What if you can't find out who's recruiting for the role?

Always aim to avoid the very impersonal "Dear Sir/Madam" - instead, opt out for "Dear HR Team" or "Dear Hiring Manager" to make a better first impression.

Your junior system administrator cover letter introduction and the value you bring

Moving on from the "Dear Recruiter" to your professional introduction.

Use those first two sentences of your junior system administrator cover letter to present the biggest asset you'd bring to the organization.

Don't go into too much detail about your achievement or the skill set, but instead - go straight for the win.

That is - what is your value as a professional?

Would you be able to build stronger, professional relationships in any type of communication? Or, potentially, integrate seamlessly into the team?

Intro Paragraph
Delving into the pioneering cloud solutions at Innovatech, I have developed a keen interest in contributing to a team that is at the forefront of technological efficiency. As a seasoned troubleshooter with a commitment to seamless network performance, I am eager to align my technical abilities with Innovatech's vision of transforming business infrastructure.

How to select your best achievement for the middle, or the junior 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 junior system administrator resume.

What else can you include in your junior 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 junior 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
While managing a 300-user network, I spearheaded an initiative to transition our backup system to a cloud-based solution, increasing data recovery speed by 50% and reducing system downtime by 30%. This pivotal enhancement significantly boosted productivity and fortified data security, showcasing my technical acumen and proactive approach to system improvement.

Ending your junior system administrator cover letter to avoid "Sincerely yours"

Yes, this sort of closing statement may work best before your signature.

But you want to give recruiters something more with your junior system administrator cover letter ending.

Some professionals choose to go down the path of promises. In a single sentence, they map out what they'd bring about to the role (whether that's a particular technical skill set or personal traits).

Others, decide to be more concrete by thanking recruiters for their time and prompting for their next interview.

Whatever path you choose, remember to always be polite and respectful of the opportunity you've had. Good manners go a long way.

Closing Paragraph
I am eager to bring my technical skills to your team. Please contact me at your convenience to schedule an interview.

Your professional ambitions could also take center stage. Describe what you plan on achieving in the next five to ten years and the efforts you're making towards your dreams.
