Dear Hiring Manager,

The layout of your projects conveys a commitment to excellence and a patient-first approach, values that deeply resonate with my professional philosophy.

At MedTech Innovations, I led a critical overhaul of the patient data query system, designing and implementing new APIs that handled billions of data points with enhanced efficiency. A highlight of this initiative was the staggeringly improved data retrieval speed and API performance—my solutions increased reliability and response time by an impressive 40%. This venture not only elevated the user experience but also fortified the infrastructure’s compliance with stringent data protection laws, an essential factor for our industry.

With a proven track record of solving complex problems and enhancing system reliability, I am enthusiastic about the prospect of contributing to your team's success. I am particularly impressed with your dedication to delivering cutting-edge solutions and am eager to bring my technical skills and passion for healthcare technology to further the profound impact of your work.

Yours sincerely,

Payton Webster

What makes this cover letter good:

  • Emphasize relevant experience: Highlighting specific, quantifiable achievements, such as improving data retrieval speed and API performance by 40% at a previous job, demonstrates the impact the applicant can have on the potential employer's projects.
  • Show alignment with company values: Drawing parallels between one's own professional philosophy and the company's commitment, such as a 'patient-first approach', shows that the candidate is a cultural fit and understands the company's mission.
  • Relevancy to the role: Focusing on expertise that directly relates to the job requirements, like the development of high-performance backend systems, clearly aligns the candidate's skills with the needs of the role.
  • Express enthusiasm for the company's work: Conveying a genuine interest in the company's initiatives and a desire to contribute to its success can set the applicant apart as someone who is likely to be passionately engaged with their work.

Structuring and formatting your infrastructure engineer cover letter

Here's what the structure of your infrastructure engineer cover letter should include:

  • Header (with your name, the position you're applying for, and the date);
  • Salutation (or greeting);
  • Introductory paragraph (or your opening statement);
  • Body paragraph (or further proof of your experience);
  • Closing paragraph (with a call to action);
  • Signature (that is optional).

Use the same font for your infrastructure engineer resume and cover letter - modern fonts like Lato and Rubik would help you stand out.

Your infrastructure engineer cover letter should be single-spaced and have a one-inch margins - this format is automatically set up in our cover letter templates and our cover letter builder.

When submitting your cover letter, always ensure it's in PDF, as this format keeps the information intact (and the quality of your document stays the same).

On one final note - the Applicant Tracker System (ATS or the software that is sometimes used to initially assess your application) won't read your infrastructure engineer cover letter.

  • Experience with infrastructure automation and configuration management tools (e.g., Ansible, Terraform, Puppet): Indicates the ability to streamline operations, increase efficiency, and ensure consistent environments across multiple deployments.

Personalizing your infrastructure engineer cover letter salutation

Always aim to address the recruiter from the get-go of your infrastructure 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.

Get creative with your infrastructure engineer cover letter introduction

Recruiters are going to assess plenty of candidate profiles for the role. Thus, anything you do to stand out will win you brownie points.

Use your infrastructure engineer cover letter introduction to share something memorable about your experience.

But before you go down the rabbit hole of creativity and humor, align your message with the company culture.

For example, if you are applying for a role in some startup, use those first two sentences to tell a funny story (about your experience) to quickly connect with the recruiter.

Intro Paragraph
Steeped in the philosophy of leveraging scalable infrastructure to drive innovation, I am poised to contribute to [Company Name]'s reputation for cutting-edge solutions. My background aligns seamlessly with the pioneering spirit and technical rigor that is synonymous with your teams and projects.

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

Now that you've got your intro covered, here comes the heart and soul of your infrastructure 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 infrastructure 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
At XYZ Corp, I spearheaded the cloud migration for a 5,000-user base, which reduced operational costs by 20% and improved system availability by 99.9%. This complex project demanded rigorous planning and deep expertise in AWS and automation tools, exemplifying my ability to deliver scalable infrastructure solutions under tight deadlines.

Finishing off your infrastructure engineer cover letter with what matters most

So far, you've done a fantastic job in tailoring your infrastructure engineer cover letter for the role and recruiter.

Your final opportunity to make a good impression is your closing paragraph.

And, no, a "Sincerely yours" just won't do, as it sounds too vague and impersonal.

End your infrastructure engineer cover letter with the future in mind.

So, if you get this opportunity, what do you plan to achieve? Be as specific, as possible, of what value you'd bring to the organization.

You could also thank recruiters for their interest in your profile and prompt for follow-up actions (and organizing your first interview).

Closing Paragraph
I am eager to bring my expertise to your team. Please contact me to schedule an interview so we can discuss my application in further detail.

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

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

Your infrastructure 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 infrastructure engineer cover letter, go into the details of how your ambitions would help make the company you're applying for better.

Key takeaways

Winning recruiters over shouldn't be difficult if you use your infrastructure engineer cover letter to tell a story that:

  • Is personalized by greeting your readers and focusing on key job skills greets;
  • Isn't spread all over the place, but instead focuses on one key achievement and selling your value as a professional;
  • Introduces your enthusiasm for the role, passion for the job, or creativity in communication;
  • Is also visually appealing - meeting the best HR practices;
  • Ends with a nod to the future and how you envision your growth, as part of the company.
