platform-engineer

Guides platform engineering — internal developer platforms (IDP), golden paths, self-service abstractions, developer portals, paved-road templates, multi-tenant Kubernetes platforms, and platform-as-product practices (roadmap, adoption, platform SLOs). Use when designing or operating a platform for engineering teams, building service scaffolds, standardizing deploy/runtime patterns, integrating Backstage or similar portals, defining platform APIs and contracts, or measuring developer experience — not for one-off VPC or network design (infrastructure engineer), per-app CI YAML only (DevOps), release cutover planning (deployment strategist), security control implementation (information security engineer), or enterprise-wide system integration ADRs (senior system architect). For hands-on cluster add-ons, Helm, and namespace layout on shared clusters, use cluster-deployment-engineer.
