Key qualities recruiters search for in a candidate’s cover letter

  • Strong analytical and problem-solving skills: Essential for designing complex hardware systems and troubleshooting issues during development.
  • Proficiency in hardware design tools: Knowledge of CAD software and simulation tools is critical for creating schematics and prototypes.
  • Experience with hardware testing and validation: Crucial in ensuring that designs meet the required specifications and reliability standards.
  • Understanding of manufacturing processes: Ensures that design is feasible within production constraints and can lead to more efficient, cost-effective solutions.
  • Excellent communication and teamwork abilities: Hardware engineers must effectively collaborate with cross-functional teams, including software engineers and project managers.

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

When writing your hardware 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 hardware 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.

  • Dear [Company Name] Team,
  • Dear [Department Name] Team,
  • Dear [Mr./Ms./Dr.] [Last Name],
  • Dear [First Name] [Last Name],
  • Dear [Job Title] Search Committee,

Introducing your profile to catch recruiters' attention in no more than two sentences

The introduction of your hardware engineer cover letter is a whole Catch 22 .

You have an allocated space of no more than just a paragraph (of up to two sentences). With your introduction, you have to stand out and show why you're the best candidate out there.

Set out on a journey with your hardware engineer cover letter by focusing on why you're passionate about the job. Match your personal skills and interests to the role.

Another option for your hardware engineer cover letter introduction is to show you're the ideal candidate. Write about how your achievements and skills are precisely what the company is looking for.

However you decide to start your hardware engineer cover letter, always remember to write about the value you'd bring about. Making it both tangible (with your metrics of success) and highly sought out.

Intro Paragraph
Driven by a relentless pursuit of innovation and a commitment to pushing the boundaries of hardware performance, I am eager to contribute to Acme Corp's legacy of groundbreaking solutions in the IoT space. My background in developing cutting-edge embedded systems aligns harmoniously with the forward-thinking philosophy Acme Corp embodies, a synergy I am keen to cultivate.

That one achievement in your hardware engineer cover letter body

The lengthiest part of your hardware engineer cover letter is the body.

Within the next three to six middle paragraphs, present yourself as the best candidate for the role.

How can you do that without retelling your whole professional resume?

Select one key achievement that covers job-crucial skills and technologies (and is memorable).

Within the body of your hardware engineer cover letter, aim to tell the story of how you achieved your success. Also, write about how this would help out your potential team.

Body Paragraph
At XYZ Tech, my redesign of an AC-DC power supply circuit for a high-volume consumer product not only improved efficiency by 15% but also reduced thermal footprint by 20%. This advancement significantly cut production costs by 5% per unit, leading to an annual savings of over $200,000, and was pivotal in extending the product's market-leading position through its acclaim in performance reliability.

Time to wrap up your hardware engineer cover letter

Writing the closing paragraph of your hardware engineer cover letter is just as important as the salutation.

You have to make it personalized to the job advert and recruiter.

Experienced professionals advise candidates to end with a request or reminder for follow-up. Write that you're grateful for the opportunity, and, at the same time, hint that you're available for the next steps of the process.

Otherwise, you could also conclude your hardware engineer cover letter by facing the future. How do you see yourself, as part of the team? In particular, how would you settle in your new role in the first six months to a year?

Closing Paragraph
I am eager to bring my expertise to your team and discuss how I can contribute to your goals. Please contact me at your earliest convenience to arrange an interview.

Is it beneficial to mention that you have no experience in your hardware engineer cover letter?

Lacking professional experience isn't the end of the world for your hardware engineer cover letter.

Just be honest that you may not have had roles in the industry, but bring about so much more.

Like, your transferable skills, attained thanks to your whole work and life experience (e.g. the skills your summer spent working abroad taught you).

Or, focus on what makes you, you, and that one past success that can help you stand out and impress recruiters (think of awards you've attained and how they've helped you become a better professional).

Alternatively, write about your passion and drive to land the job and the unique skill set you would bring to enhance the workplace culture.
