DevOpsエンジニアの職務経歴書例（シニア）

“Significant production experience with Kubernetes (ideally GKE) and packaging/deploying workloads with Helm.”

“Design and evolve our cloud architecture on GCP - networking, interconnects, IAM and high-availability topology - and express it entirely as code with Terraform, following GitOps as a first principle.”

“Build and own the CI/CD pipelines that plan, review, test and safely apply IaC changes - Policy-as-Code guardrails, drift detection and progressive rollout so infrastructure changes ship as confidently as application code.”

“Strengthen our observability stack - metrics, logs, traces and alerting across Prometheus, Thanos, Grafana, Loki, Tempo and Alertmanager - so the platform is easy to run and reason about.”

“Proven experience building CI/CD pipelines for IaC - automated plan/apply, code review, Policy-as-Code, drift detection and safe rollout.”

“Working proficiency in Go for automation and tooling.”

“Participate in our Follow-The-Sun on-call model: watch and triage alerts, join and declare incidents, lead structured debugging and escalation, and drive blameless post-mortems and the post-actions that actually close the loop.”

“5+ years in a DevOps, Platform/Infrastructure, or SRE role, with a proven track record operating large-scale, high-availability, high-performance systems in production.”

“Security and compliance experience in a regulated environment (SOC 2, secrets management, audit logging).”

“Strong grasp of incident management end to end: joining and declaring incidents, structured debugging under pressure, escalation, clear documentation, and post-mortems that drive real change.”
