What should your reliability engineer 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 reliability engineer cover letter? Our builder sets those up for you with:

  • Header - dedicated to your contact information, the role you're applying for, and the date (don't forget to include your name);
  • Greeting and opening paragraph - to create a personalized and memorable experience for recruiters;
  • Body paragraph - emphasizing your skill set and knowledge that aligns with the role and helps you to stand out;
  • Closing paragraph - leaving a great impression and ending with an optional signature.

Use a cover letter template to discover the best formatting for your reliability engineer cover letter: that is single-spaced paragraphs and wrapping your content in a one-inch margin.

Ensure that both your resume and reliability engineer cover letter are in the same font. Stand apart from the crowd by using modern, yet simple fonts, like Chivo and Rubik, instead of the overused Arial and Times New Roman.

Did you know that the Applicant Tracker System (or ATS) won't be assessing your reliability engineer cover letter? Instead, submit your profile in PDF to recruiters to keep the same formatting and the design intact.

Kick off your reliability engineer cover letter: the salutation or greeting

When writing your reliability engineer 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 reliability engineer 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.

Your reliability engineer 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 reliability engineer 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
Intrigued by the opportunity to contribute to a company that prides itself on its commitment to operational excellence and pioneering sustainability initiatives, joining your team as a Reliability Engineer feels like the perfect alignment of my expertise in systems optimization and passion for eco-efficient engineering solutions.
RIGHT

What comes next: your reliability engineer cover letter middle paragraphs

In the next three to six paragraphs (or the body of your reliability engineer cover letter) you have to prove your unique value.

Most candidates tend to mess up at this stage. They tend to just copy-paste information from their resume.

That's one big no-no.

Remember that when writing your reliability engineer cover letter, it has to be personalized. And, your ultimate aim is to catch the recruiter's eye.

So, look back on key job requirements and write down a list that includes the ones you cover.

Next, select just one key achievement from your professional (or personal) history that meets those advert keywords.

Narrate a story around how you've grown your skill set and knowledge. Also, aim to show the unique understanding or soft skills you bring about, thanks to your past success.

Body Paragraph
Instrumental in redesigning a high-traffic production line, I implemented advanced fault tree analysis techniques. This strategic overhaul slashed downtime by 33% and resulted in a sustained 15% increase in overall equipment effectiveness (OEE), showcasing my proficiency in reliability engineering and continuous improvement practices.

Two ideas on how to end the final paragraph of your reliability engineer cover letter

Closing your reliability engineer cover letter, you want to leave a memorable impression on recruiters, that you're a responsible professional.

End your cover letter with how you envision your growth, as part of the company. Make realistic promises on what you plan to achieve, potentially, in the next six months to a year.

Before your signature, you could also signal hiring managers that you're available for the next steps. Or, a follow-up call, during which you could further clarify your experience or professional value.

Closing Paragraph
Eager to discuss how my skills align with your goals, I welcome the opportunity for an interview at your earliest convenience.
RIGHT

Lacking experience: here's how to write your reliability engineer cover letter

As a candidate with no experience, it's important to be honest from the get-go of your application.

Use your reliability engineer cover letter to sell your unique talents. Choose an accomplishment from your academic background or your volunteer work to show the skills that are relevant to the role.

Focus on your career objectives and how you see the job to align with them. Be specific and, at the same time, realistic about where you picture yourself in five years.

Key takeaways

Creating your reliability engineer 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.
