Design Engineer cover letter example


New York, NYC



Dear Hiring Manager,

I am writing to express my interest in the Mechanical Engineer position at your esteemed company. My extensive background in mechanical engineering, combined with my drive to improve processes and systems, makes me an excellent fit for your team. I am particularly impressed by your commitment to innovation and excellence in the aerospace and defense sector, which aligns perfectly with my experience and professional values.

During my tenure at Rau-Ward, a lead provider of products to the oil and gas industry, I managed to cut down the cycle time of a crucial manufacturing process. Specifically, I reduced the cycle time of a batch of pre-cured strips by a full minute through meticulous time and motion analysis. Additionally, by re-evaluating component configurations, I successfully decreased the requirement for fasteners by 25%, significantly reducing material costs and simplifying the assembly process. These enhancements not only streamlined production but also contributed to a substantial increase in efficiency and profitability for the company.

I am eager to bring my track record of success and commitment to efficiency to your team. My proactive approach and continuous improvement focus have consistently generated positive outcomes, and I am confident in my ability to contribute to your company’s mission. I would be grateful for the opportunity to discuss how my background, skills, and certifications align with the needs of your organization.



Mechanical Engineer
What makes this cover letter good:

  • Quantifiable Achievements: Including specific achievements with measurable outcomes, like reducing cycle time by a full minute and decreasing the use of fasteners by 25%, effectively demonstrates the candidate's ability to contribute to efficiency and cost savings.
  • Relevant Experience: Highlighting experience in related industries to the company's focus, such as the aerospace and defense sector, provides the hiring manager with evidence of the applicant's applicable background and potential for a smooth transition into the role.

  • Customization to Company Goals: Tailoring the cover letter to reflect the company's mission and values, as well as expressing enthusiasm for contributing to those goals, can help the candidate establish a connection with the employer and demonstrate a strong cultural fit.
  • Designing your design engineer cover letter: what is the best format

    Let's start with the basics, your design engineer cover letter should include your:

    • Header
    • Greeting
    • Introduction
    • Body paragraph
    • Closing statement
    • Signature (that's not a must)

    Next, we'll move to the spacing of your design engineer cover letter, and yes, it should be single-spaced (automatically formatted for you in our cover letter templates).

    Don't go for a old-school font (e.g. Arial or Times New Roman), but instead, pick an ATS-favorite like Chivo, Volkhov, or Raleway, to stand out.

    Our cover letter builder is also set up for you with the standard one-inch margin, all around the text.

    Finally, ensure your design engineer resume and cover letter are in the same font and are submitted in PDF (to keep the formatting in place).

    P.S. The Applicant Tracker System (or ATS) won't be assessing your [job] cover letter, it's solely for the recruiters' eyes.

    Personalizing your design engineer cover letter salutation

    Always aim to address the recruiter from the get-go of your design engineer cover letter.


    • the friendly tone (e.g. "Dear Paul" or "Dear Caroline") - if you've previously chatted up with them on social media and are on a first-name basis;
    • the formal tone (e.g. "Dear Ms. Gibbs" or "Dear Ms. Swift") - if you haven't had any previous conversation with them and have discovered the name of the recruiter on LinkedIn or the company website;
    • the polite tone (e.g. "Dear Hiring Manager" or "Dear HR Team") - at all costs aim to avoid the "To whom it may concern" or "Dear Sir/Madam", as both greetings are very old-school and vague.

    The design engineer cover letter introduction: focusing on your unique value, with a creative twist

    You are not the only one wondering how to start your design engineer cover letter. Those first two sentences introduce your profile and should be memorable.

    No pressure.

    When beginning your design engineer cover letter, immediately point out the unique value of working with you. In other words, what you promise to bring to the role by using your past track record of success.

    Start your design engineer cover letter with a creative twist by telling a joke or stating something relatable. Select this type of introduction only if it aligns with the company culture.

    Intro Paragraph
    Immersed in the latest sustainable design practices, I am keen to contribute to the pioneering solutions at TerraFirma Dynamics, known for its commitment to environmental innovation. My track record in designing energy-efficient systems aligns seamlessly with your company's mission to redefine industry standards.

    Choosing your best achievement for the middle or body of your design engineer cover letter

    Now that you have the recruiters' attention, it's time to write the chunkiest bit of your design engineer cover letter.

    The body consists of three to six paragraphs that focus on one of your achievements.

    Use your past success to tell a story of how you obtained your most job-crucial skills and know-how (make sure to back these up with tangible metrics).

    Another excellent idea for your design engineer cover letter's middle paragraphs is to shine a light on your unique professional value.

    Write consistently and make sure to present information that is relevant to the role.

    Body Paragraph
    At my previous role at InnovTech, I successfully led the design of a new sustainable housing project, where I reduced the overall material costs by 20% while still meeting all environmental and safety standards. This accomplishment was a result of meticulous design optimization and collaborative supplier negotiations. My approach not only saved the company $500,000 over the project's lifecycle but also won the 2021 Eco-Smart Design Award, reflecting my commitment to cost-efficiency and sustainable engineering solutions.

    Final words: writing your design engineer cover letter closing paragraph

    The final paragraph of your design 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 design 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
    I eagerly anticipate discussing how my skills will benefit your team. Please contact me to arrange an interview.

    Design Engineer cover letter advice for candidates with no experience

    If you're worried about writing your Design Engineer cover letter and have no professional experience, we sure have some advice for you.

    Turn recruiters' attention to your transferable or relevant skills gained thanks to your life and work experience.

    Instead of writing about past jobs, focus on one achievement (whether from your volunteering experience, education, etc.) and the skills it has helped you build.

    Alternatively, you could focus your Design Engineer cover letter on your career objectives and goals. Always remember to make those relevant to the job you're applying for by detailing how you see yourself growing as part of the company.

    Recruiters would be way more impressed with candidates who fit the job profile and can bring about plenty of skills and vision to the table.
