Example Cover Letter: DevOps Engineer
Dear CoreOps Team,
I am writing to apply for the DevOps Engineer position at CoreOps Cloud. With five years of experience building and maintaining cloud infrastructure for SaaS products, I specialize in designing reliable, cost-efficient systems that let developers focus on shipping rather than firefighting.
In my most recent role, I reduced our monthly AWS spend by $45k through right-sizing and spot instance strategies, while simultaneously improving deployment frequency from weekly to multiple times per day. I also led our SOC 2 Type II compliance effort, coordinating across engineering, security, and legal teams.
CoreOps' emphasis on infrastructure as code and developer experience is exactly the environment where I do my best work. I would love to bring my Terraform, Kubernetes, and platform engineering experience to your team.
Thank you for your consideration.
