Job Description:

Are you ready to shape the future of AI-powered infrastructure? Hitachi Energy is expanding its Grid Solutions team and seeking a Principal Power Systems Architect to lead the electrical design of next-generation hyperscale AI data centers.

This is a unique opportunity to become the technical authority behind some of the world's most advanced and energy-intensive facilities. In this role, you will own the end-to-end electrical architecture, from high-voltage utility interconnections and transmission systems through medium- and low-voltage distribution networks to rack-level power delivery. You will help define the future of data center electrification by driving innovative, reliable, and scalable solutions that support the rapidly growing demands of artificial intelligence.

Working alongside a team of specialist engineers, you'll guide complex technical studies, influence critical design decisions, and collaborate with utilities, grid operators, EPCs, OEMs, and industry stakeholders. Your expertise will help ensure resilient, compliant, and efficient power systems that enable the next generation of digital infrastructure.

If you are passionate about power systems engineering, large-scale infrastructure, and solving complex technical challenges while leading high-impact projects, this role offers the opportunity to make a lasting contribution to the energy transition and the future of AI.

• Lead the electrical architecture of hyperscale AI data center campuses from grid connection to rack-level power.
• Direct multidisciplinary power system studies and ensure alignment across engineering domains.
• Develop utility interconnection strategies and support large-load grid integration initiatives.
• Review and approve key technical studies, designs, and engineering deliverables.
• Define system-level specifications for transformers, power electronics, BESS, reactive compensation, and UPS solutions.
• Serve as the primary technical interface for utilities, EPCs, grid operators, and equipment suppliers.
• Identify and mitigate technical risks throughout the project lifecycle.
• Mentor engineering teams and foster technical excellence across power systems disciplines.

• Master's degree or Ph.D. in Electrical Engineering with a focus on power systems, grid dynamics, power electronics, or high-voltage systems.
• Minimum 15 years of relevant industry experience in power systems engineering and large-scale infrastructure projects.
• Proven experience with utility interconnection processes, grid compliance requirements, and large-load integration in North America.
• Strong knowledge of ANSI, IEEE, UL, and NERC standards applicable to power system design and operation.
• Experience with industry-leading simulation tools such as PSS4E, PowerFactory, PSCAD, or similar platforms.
• Demonstrated ability to work across power systems, data center infrastructure, controls, power electronics, and related engineering disciplines.

Responsible to ensure compliance with applicable external and internal regulations, procedures and guidelines.
