Dear Hiring Manager,

I am writing to express my interest in contributing my expertise in material science and laser technology to your esteemed company. My proactive approach and proven ability to improve processes and performance through innovative technologies align seamlessly with the forward-thinking ethos I've observed at your organization.

At TechMaterials Inc., I led a team to significantly enhance industrial ceramic processing through advanced laser technology. The resultant material performance improvement of 25% was not only a testament to our team's dedication but also a benchmark in the industry for efficiency gains. Furthermore, I spearheaded the development of an electro-optical characterization method that revolutionized material testing in our labs, achieving a 40% reduction in testing time and markedly increasing throughput. These concrete results demonstrate my capability to drive substantial improvements in a lab environment and to deliver quantifiable success within a high-tech industry setting.

I am eager to bring my hands-on experience and proactive problem-solving skills to your dynamic team. I am confident that my background in optimizing laser applications and collaborative approach to integrating new technologies will contribute effectively to your company's continuous improvement and innovation. Please consider this letter as an expression of my interest in the opportunity and an invitation to discuss how my skills and experiences align with the goals of your organization.

Designing your application engineer cover letter: what is the best format

Let's start with the basics, your application 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 application 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 application 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.

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

  • Technical proficiency in relevant software and programming languages: Demonstrates the ability to build, maintain, and optimize the applications that the company develops or utilizes.

  • Experience with the entire software development lifecycle: Shows an understanding of how to contribute from initial concept to deployment and maintenance, aligned with best practices for application development.

  • Strong problem-solving skills: Essential for diagnosing and troubleshooting issues within applications, ensuring functionality and user satisfaction.

  • Effective communication and collaboration abilities: Highlights the capacity to work well with cross-functional teams, including developers, product managers, and customer support, which is critical in an application engineering role.

  • Familiarity with current industry trends and emerging technologies: Indicates an ongoing commitment to staying updated on new tools and practices that can benefit the development process and foster innovation.

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

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

With your application 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".

List of salutations you can use

  • Dear Hiring Manager,
  • Dear [Company Name] Team,
  • Dear [Hiring Manager's Name],
  • Dear [Department Name] Hiring Committee,
  • Dear Recruiter,
  • Good Day [Hiring Manager's Name],

Your application 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 application 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 pioneering software solutions that power progressive industries, I am invigorated by the opportunity to contribute to [Company Name]'s commitment to cutting-edge technology and user-centric design.

How to select your best achievement for the middle, or the application engineer 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 application engineer resume.

What else can you include in your application engineer 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 application engineer 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
At my previous role, I spearheaded the development of a new feature that resulted in a 150% increase in user engagement. This involved coordinating a cross-functional team, optimizing the app's performance under high traffic conditions, and integrating user feedback to refine functionality. My blend of technical acumen and project management ensured timely delivery, surpassing stakeholder expectations and significantly boosting user satisfaction metrics.

Final words: writing your application engineer cover letter closing paragraph

The final paragraph of your application 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 application 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 discuss how my skills align with the goals of your team, I welcome the opportunity to interview at your earliest convenience.

Which story should you tell in your application engineer cover letter when you have zero experience

Candidates, lacking professional experience in the field - this one is for you.

Your application engineer cover letter is an exercise of integrity, honesty, and, above all, spinning a positive narrative around your strengths.

And what better way to capture recruiters' attention than with your most job-relevant achievement (this could be from your internship or volunteering experience)?

Make sure to back up your success with transferrable skills that are relevant to the job (e.g. how your year, studying abroad, has taught you to be more motivated and handle multicultural environments).

Another safe card you can bet on is your career dream: in the body of your application engineer cover letter, go into the details of how your ambitions would help make the company you're applying for better.

Key takeaways

Writing your application engineer cover letter doesn't need to turn into an endless quest, but instead:

  • Create an individual application engineer cover letter for each role you apply to, based on job criteria (use our builder to transform your resume into a cover letter, which you could edit to match the job);
  • Stick with the same font you've used in your resume (e.g. Raleway) and ensure your application engineer cover letter is single-spaced and has a one-inch margin all around;
  • Introduce your enthusiasm for the role or the company at the beginning of your application engineer cover letter to make a good first impression;
  • Align what matters most to the company by selecting just one achievement from your experience, that has taught you valuable skills and knowledge for the job;
  • End your application engineer cover letter like any good story - with a promise for greatness or follow-up for an interview.
