DevOps Engineer cover letter sample
Dear Hiring Manager,
I am excited to apply for the DevOps Engineer position at [Company Name]. I am a DevOps engineer with 6 years of experience running AWS infrastructure with Kubernetes and Terraform.
In my current role as DevOps Engineer at Brightpath Health Tech, I migrated 40 services to Kubernetes (EKS) with Terraform, taking deploys from weekly to 30+ a day. I also kept 99.95% uptime across production for 3 years, with on-call alerts cut by half through better thresholds.
Before that, as Systems Engineer at Lone Star Hosting, I automated server provisioning with Ansible, cutting setup from 2 days to 30 minutes. The skills I would bring to [Company Name] include AWS (EKS, EC2, RDS, IAM); Kubernetes and Docker; and Terraform and Ansible.
I would love to discuss how my experience fits your team's plans for the year ahead. Thank you for considering my application.
Sincerely,
Lucas Silva

How to write a devops engineer cover letter
- 1. Open with the role and your strongest match
Name the job and the company, then sum up who you are in one sentence, as the sample does: “I am a DevOps engineer with 6 years of experience running AWS infrastructure with Kubernetes and Terraform.”
- 2. Prove it with one or two results
Pick the achievements that matter most for this employer and keep the numbers. For a devops engineer, a result like “Migrated 40 services to Kubernetes (EKS) with Terraform, taking deploys from weekly to 30+ a day.” says more than a list of duties.
- 3. Show the skills the posting asks for
Mention the tools and skills from the job description that you genuinely have, for example: AWS (EKS, EC2, RDS, IAM); Kubernetes and Docker; Terraform and Ansible; GitHub Actions and Jenkins.
- 4. Close with a clear next step
Thank the reader and say you would welcome a conversation. Keep the whole letter to one page.
Mistakes to avoid
- !Repeating your resume line by line instead of choosing the two results that matter most for this job
- !Opening with "I am writing to express my interest" - start with the role and why you fit
- !Sending the same letter to every employer without naming the company or the role
- !A tool list with no evidence of scale
Frequently asked questions
- How long should a cover letter be?
- Between 250 and 400 words on one page: an opening, one or two paragraphs of evidence and a short close.
- Who should I address it to?
- Use the hiring manager’s name when you can find it. Otherwise “Dear Hiring Manager” or “Dear [Company] Hiring Team” is fine.
- Do I need a cover letter if it is optional?
- Yes, when you can tailor it. A short, specific letter is one of the easiest ways to stand out from applicants who skip it.
