Principal Site Reliability Engineer

Hitachi Energy is seeking a Principal Site Reliability Engineer to ensure the secure, reliable, and efficient operation of cloud‑hosted environments that support ESS software products and customer deployments.

The Site Reliability Engineering (SRE) competency within Cloud Operations ensures our SaaS products are reliable, scalable, secure, and cost efficient across AWS and Azure. The SRE role combines software engineering and operations to improve service reliability and operational excellence, including critical incident response, proactive problem management, error budgets, and toil reduction.

Responsibilities include ensuring operational excellence through consistent execution of cloud operations processes, continuous improvement initiatives, and cross functional collaboration with Product Development (R&D), Architecture, and Customer Experience (CX) teams.

A core responsibility is leading Cloud Maturity Assessments across products and cloud platforms, identifying gaps in cloud deployment/security/operational readiness, and partnering with Product Development (R&D), DevOps, Program Management Office (PMO), and SecOps to drive remediation into roadmaps and releases.

This role will require close partnership with Product Development (R&D), Quality, Security, and Customer Experience (CX) teams as part of supporting reliable product delivery and customer operations. In addition, the role will engage with peer cloud, infrastructure, and platform teams across the broader organization.

Duties and Responsibilities:

* Lead Cloud Maturity Assessments across products deployed on AWS and Azure, using standardized scoring templates, weighted maturity dimensions, and executive reporting (heatmaps/dashboards) to identify maturity gaps and translate findings into an actionable improvement backlog.

* Define and implement reliability standards for observability, establish service health practices, and drive consistent operational practices across products and platforms to enable scalable “run” operations and consistent SLAs.

* Facilitate cloud provider / internal and operational readiness reviews (FTR/WAFR‑style) to ensure workloads meet validated standards and coordinate follow‑on “day‑2” operational improvements identified during reviews.

* Implement SRE best practices: SLIs/SLOs, error budgets, capacity planning, load/performance considerations, and automation to reduce operational toil.

* Lead post‑incident reviews and reliability improvements that measurably improve uptime, resilience, and operational consistency.
