A Cloud Engineer cover letter that gets read.

Dear Hiring Manager, When [Company] processes [specific number] of requests daily across multi-region deployments, infrastructure reliability becomes non-negotiable. As a Cloud Engineer with [X years] of hands-on experience architecting and maintaining cloud systems, I've built similar scale by designing Kubernetes clusters that reduced deployment time by [percentage] and implementing Infrastructure-as-Code practices that decreased infrastructure provisioning from weeks to hours. My work directly supports software engineering teams by removing bottlenecks—whether through optimizing CI/CD pipelines, managing containerization strategies, or ensuring observability across distributed systems. In my current role at [Previous Company], I've developed expertise in the core areas this position demands: cloud platform architecture (primarily [AWS/GCP/Azure]), Terraform and CloudFormation for IaC, Docker and Kubernetes orchestration, and monitoring solutions using [specific tools]. Most recently, I led a migration of [specific workload] that improved system performance by [metric] while reducing cloud costs by [percentage]. I've also mentored junior engineers on cloud best practices and contributed to runbooks that reduced MTTR for production incidents by [percentage]. What attracts me to [Company] is your commitment to [specific technical initiative or company detail]. I'm eager to apply my expertise in cloud infrastructure to accelerate your engineering team's velocity and maintain the reliability standards your users depend on. I'd welcome the chance to discuss how my experience with [specific relevant technology or challenge] can directly contribute to your infrastructure goals.
