This is the section where round two of the screen actually happens, the closing gate before an
interview hits your inbox. A recruiter takes their time here, and even at that, the current
role still drives around 95% of the result.
That tracks: nothing proves what you can run in production today like the seat you sit in
right now. To earn a "yes", the section has to hit every entry on the
Cloud Engineer role profile, one bullet per domain you named in Domain
Expertise above. Every bullet has to come off something you genuinely held in production,
never a ticket that landed on your queue.
1
Cloud Architecture & Landing Zones
The flagship work of the role. Show the landing zone you designed, the account topology under
it, and the workloads the architecture now carries. Name the design and what it enabled, not
"worked on cloud architecture".

Cost Optimization & FinOps
Where Cloud Engineering meets the business. Show the FinOps program you set up, the

Reliability, DR & Compliance
The discipline that keeps the cloud estate trusted by the business. Show the DR posture you

Tooling & Workflow
The setup that lets one Cloud Engineer carry a multi-account estate. Show the IaC modules
you authored, the review patterns that catch a bad VPC change at PR time, and the docs that
