Platform / DevOps Engineer → SRE
Build the systems other engineers depend on. Requires coding fluency. Rarely entry-level.
Where senior cloud and DevOps people end up when they want to be treated as engineers, not as ticket-takers. Highest ceiling in this list, but almost never an entry role.
You write code comfortably, you've owned production systems, and you find the idea of building an internal developer platform genuinely interesting rather than just a job title.
You want to get there in two years from a helpdesk seat. The job assumes years of coding plus years of running infrastructure, and there's no real shortcut.

Certification sequence
Ordered by realistic relevance, not vendor marketing.
Practical projects
What to actually build, the portfolio that opens interviews.
- Self-hosted CI with GitHub Actions runners
- GitOps with ArgoCD on a homelab cluster
- SLO dashboards in Grafana with synthetic checks
- ·Cloud-first then add automation
- ·Backend dev then add ops
Realistic expectations
What no recruiter will tell you.
That it's just DevOps with a new label. Platform engineering is product work. You're building tools other engineers depend on, with a roadmap, users and feedback loops.
Twelve to twenty-four months from a strong cloud or backend role. Cold entry isn't really a thing here, and the postings that say otherwise are usually mis-titled SRE roles.

Where this fits
A pathway is a sequence, not a destination. Here are the roles and certs along it.
- Cloud Engineer → Cloud Architect
Highest-paid generalist track. Stack: networking + Linux + cloud + IaC.
- Cloud Security Engineer
Cloud-native IAM, workload security, policy-as-code. Entered from cloud, not from SOC.
- Software Engineer (Backend / Full-stack)
Ship product, own services. Portfolio matters more than certs.
- Cloud engineering isn't entry-level anymore
In progress. The market that hired junior cloud engineers in 2019 doesn't exist. What replaced it, and the realistic path in.
- DevOps vs platform engineering. What actually changed
In progress. It isn't a rename. The hiring bar, day-to-day, and career ceiling are all different. Most candidates pick the wrong one.
The next step
The pathway is plausible. Whether it holds for five years is a different question.
