What greeting should you use in your mechanical engineer cover letter salutation

A simple "Hello" or "Hey" just won't work.

With your mechanical engineer cover letter salutation, you set the tone of the whole communication.

You should thus address the hiring managers by using their first (or last name) in your greeting.

But how do you find out who's recruiting for the role?

The easiest way is to look up the role on LinkedIn or the corporate website.

Alternatively, you could also contact the organization via social media or email, for more information.

Unable to still obtain the recruiter's name?

Don't go down the "To whom it may concern path". Instead, start your cover letter with a "Dear HR team".

top sections icon

List of salutations you can use

  • Dear Hiring Manager,
  • Dear [Specific Job Title] Hiring Team,
  • Dear [Specific Name of the Hiring Manager if known],
  • Dear [Company Name] Recruitment Team,
  • Dear [Department Name] Team,
  • Dear Sir/Madam,

Your mechanical 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 mechanical 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
With a proven track record in innovative mechanical design and a deep respect for [Company Name]'s commitment to sustainable engineering solutions, I am keen to contribute my expertise towards delivering high-efficiency projects that align with the company's visionary approach to the industry.

What to write in the body of your mechanical engineer cover letter

Now that you've got your intro covered, here comes the heart and soul of your mechanical engineer cover letter.

It's time to write the middle or body paragraphs. This is the space where you talk about your relevant talent in terms of hard skills (or technologies) and soft (or people and communication) skills.

Keep in mind that the cover letter has a different purpose from your mechanical engineer resume.

Yes, you still have to be able to show recruiters what makes your experience unique (and applicable) to the role.

But, instead of just listing skills, aim to tell a story of your one, greatest accomplishment.

Select your achievement that:

  • covers job-crucial skills;
  • can be measured with tangible metrics;
  • shows you in the best light.

Use the next three to six paragraphs to detail what this success has taught you, and also to sell your profile.

Body Paragraph
In my role at Automaton Works, I led the design of a new gearbox that reduced production costs by 20% while enhancing efficiency by 15%. My innovative approach to material selection and gear geometry, backed by extensive FEA simulations, not only met but surpassed the client's requirements for a high-performance, cost-effective solution, positioning us as the go-to vendor in a highly competitive market.

Final words: writing your mechanical engineer cover letter closing paragraph

The final paragraph of your mechanical engineer 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 mechanical engineer 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
Eager to bring my technical expertise to your team, I welcome the opportunity to discuss how my skills align with the goals of your company and to arrange an interview.

Addressing limited to no experience in the mechanical engineer cover letter

There's nothing to worry about if you lack professional experience.

Your mechanical engineer cover letter could bridge the gaps in your professional history by focusing on what matters most to recruiters, that's either:

  • skills - focusing on transferable ones you've gained, thanks to your life experience (e.g. volunteering, certificates, etc.);
  • achievements - select the most relevant and noteworthy one from your history (e.g. education, projects, etc.);
  • motivation - describe how you envision your professional growth in the next up to five years, thanks to this opportunity.

Key takeaways

We hope this mechanical engineer cover letter writing guide has shown you how to:

  • Format your mechanical engineer cover letter with the mandatory sections (e.g. header, greeting, intro, body, and closing) and select the right font (P.S. It should be the same as the one you've used for your resume);
  • Substitute your lack of professional experience with your most noteworthy achievement, outside of work, or your dreams and passions;
  • Ensure recruiters have a more personalized experience by tailoring your cover letter not just to the role, but to them (e.g. writing their first/last name in the salutation, etc.);
  • Introducing your biggest achievement and the skills it has taught you in your mechanical engineer cover letter body;
  • Write no more than two sentences in your mechanical engineer cover letter introduction to set the right tone from the get-go.
