🏢 About HITACHI ENERGY

Hitachi Energy is at the forefront of advancing sustainable energy systems, aiming for a carbon-neutral future. Working here means you'll contribute to critical infrastructure that powers the green transition, with a strong emphasis on innovation and reliability.

About This Role

As a DevOps Engineer, you'll design and maintain hybrid infrastructure with a core focus on Kubernetes container orchestration. You'll build and manage CI/CD pipelines using GitHub Actions and ArgoCD, and implement monitoring with Prometheus/Grafana to ensure high system reliability for sustainable energy solutions.

💡 A Day in the Life

A typical day might start with monitoring dashboards in Grafana to check system health, then attending a stand-up to discuss pipeline issues. You might spend the morning automating a deployment with Helm and ArgoCD, and the afternoon troubleshooting a Kubernetes cluster performance problem or refining Terraform modules for new infrastructure.

⚠️ Common Mistakes to Avoid

  • Don't list generic DevOps skills without tying them to the specific tools (Kubernetes, GitHub Actions, ArgoCD, Prometheus, Grafana).
  • Avoid vagueness about your experience level—be explicit about years and depth, especially with Kubernetes.
  • Don't neglect security and networking; these are critical in hybrid environments, so be ready to discuss them.
