About This Role

As an IAM Engineer specializing in Active Directory, you will be the backbone of identity and access management for Hitachi Energy's global operations. Your work ensuring robust AD infrastructure, automating tasks with PowerShell, and supporting AWS integration directly supports secure, reliable energy systems. This role is critical for maintaining operational integrity and enabling digital transformation initiatives.

💡 A Day in the Life

A typical day starts with checking AD health dashboards and resolving any overnight alerts or replication issues. You might spend the morning troubleshooting a Tier 3 escalation from the help desk, then develop a PowerShell script to automate user offboarding. Afternoons could involve coordinating with the cloud team on AWS EC2 integrations or planning a domain controller upgrade, all while collaborating via Slack and video calls with a global team.

3

Explicitly mention any experience with AWS EC2 or Quest tools (e.g., Recovery Manager for AD) in a dedicated skills section, as these are pluses.

4

Tailor your cover letter to connect your AD expertise to Hitachi Energy's mission of sustainable energy—e.g., how secure IAM supports reliable power grids.

Research Hitachi Energy's recent news on digital transformation or sustainability projects and subtly reference them in your application to show genuine interest.

⚠️ Common Mistakes to Avoid

  • Avoid vague statements like 'I have experience with AD'—be specific about years, scale, and complex scenarios.
