Ms Revathi Iyer

Head of Platform Engineering

Saarthiroute Logistics Software

Subject: Application for DevOps Engineer

Dear Ms Iyer,

Ninety minutes was a typical deployment at Nandibetta Cloudworks until I automated our release checks in GitHub Actions; now it takes 12. Making that kind of change for the product teams at Saarthiroute Logistics Software is why I am applying to be your DevOps Engineer.

I run the AWS platform and the pipelines that 12 development teams use, with 40 services on Kubernetes (EKS) watched by Prometheus and Grafana. All of it lives in Terraform, and every change goes through a reviewed pull request. Resizing idle servers and adding scheduled shutdowns cut cloud spend by 22%, about ₹85 lakh a year. After I wrote runbooks for the ten most common incidents, mean time to restore fell from 70 to 35 minutes.

Saarthiroute has 15 product teams, a few more than I support today, and a festive-season peak when a bad release can stop trucks leaving a warehouse. That is where a shared pipeline pays off. I built a template with tests, security checks and rollback that eight teams adopted within a quarter, and I would offer the same to your teams before October. I already join the on-call rota one week in six, and I began as a systems administrator looking after 80 Linux servers, so I write runbooks for common incidents with the person woken at night in mind.

Release freezes before a busy season are usually where pipelines and product teams clash, so my first question is how yours are run today. With company details removed, the pipeline template is ready to walk through in a first meeting.

Regards,

Prashanth Gowda

Paragraph by paragraph

  1. The opening

    Starts: “Ninety minutes was a typical deployment at…”

    Opens on the old deployment time and the new one, so the reader meets the result before the tools.

  2. Your strongest evidence

    Starts: “I run the AWS platform and the…”

    Names the cloud, the infrastructure tool and the monitoring stack in one place, then answers the cost and incident lines with figures.

  3. Why this employer

    Starts: “Saarthiroute has 15 product teams, a few…”

    Gives a reason rooted in the employer's size and season, and answers the on-call and runbook line in the advert's own words while stating the on-call load plainly.

  4. The close

    Starts: “Release freezes before a busy season are…”

    Asks one question specific to a seasonal business and offers a work sample, which keeps the close concrete.

Why this letter works

  • Tools are named once, in the evidence paragraph, where a platform lead looks for them.
  • A saving in rupees and a halved restore time sit beside speed, which shows delivery did not come at reliability's expense.
  • The reason for applying is the employer's scale and festive-season peak, facts taken from the advert.
  • The closing question about release freezes is one only someone who has run a busy season would ask.

How to write your own devops engineer cover letter

  1. Give deployment time before and after, and name the CI tool that made the difference.
  2. Put a cloud saving as a percentage and in rupees a year, and say what you changed to get it.
  3. State your on-call rota plainly; platform leads want to know you have carried a pager.
  4. Mention any pipeline template other teams adopted, with how many and how fast.
  5. Ask about release freezes if the employer has a festive or year-end peak.

Common questions

Which tools should a DevOps engineer name in the letter?

The cloud, the infrastructure-as-code tool and the CI system, ideally the ones in the advert. Monitoring tools can follow if there is room.

Should I mention cost savings if cost was not in the advert?

A short line is worth it. Most platform teams answer to a cloud bill, and a measured saving shows judgment as well as skill.

How do I show reliability rather than only speed?

Pair a delivery figure with a restore time or an incident figure, so the reader sees faster releases did not mean more outages.
