I’m applying for the Cloud Engineer position at Datadog. After three years of managing multi-cloud infrastructure and watching my team rely on Datadog dashboards to keep everything running, I’d love to help build the monitoring platform from the inside.
At my current role at a healthcare SaaS company, I led our cloud migration from on-premise VMware to AWS, moving 45 services over 8 months with zero unplanned downtime. I designed the landing zone architecture using AWS Organizations, implemented guardrails with Service Control Policies, and built the IaC foundation in Terraform that our 6 engineering teams now use for all infrastructure changes.
I also reduced our monthly AWS bill by 34% ($28K/month) through a combination of right-sizing, Reserved Instance planning, Savings Plans, and spot instance adoption for batch workloads. Beyond cost, I implemented a disaster recovery strategy with cross-region replication that brought our RTO from 24 hours to under 45 minutes.
I’d welcome the chance to discuss how my cloud architecture and operational experience could contribute to Datadog’s infrastructure team. I’m available anytime.
Five things this cover letter does that most cloud engineer applications don’t.
Ryan’s team depends on Datadog — so applying to build it isn’t just career ambition, it’s contributing to a tool they already trust. This personal connection is genuine and verifiable.
45 services migrated with zero unplanned downtime over 8 months is a headline accomplishment. It shows Ryan can plan and execute at scale, not just manage existing infrastructure.
$28K/month in savings is concrete and impressive. It proves Ryan thinks about infrastructure as a business function, not just a technical one.
Reducing RTO from 24 hours to 45 minutes shows Ryan doesn’t just build systems — they prepare for when things go wrong. This is critical for infrastructure roles.
Ryan summarizes their value proposition in two words: “cloud architecture and operational experience.” Concise and directly relevant to the role.
