devops engineer cover letter example (2026)
A DevOps cover letter should show the path from commit to prod and one incident — not a cloud certification list.
When this letter is worth sending
Useful when the posting mixes SRE and DevOps language and you need to show which one you actually did.
Example letter (teaching draft)
Fictional names and companies. Copy the structure, not the metrics. If you cannot discuss a line in an interview, delete it.
Dear Hiring Manager, I am applying for the DevOps Engineer role because you want deploys that match staging, not a wiki of bash. At Lumina I moved deploys to GitHub Actions and Terraform so staging stopped being a snowflake. Paging moved from CPU to error-rate after a checkout outage that sales noticed first. I will not put 99.99% on a letter. I will walk through the runbook. Best, Alex Patel
