Principal Electrical Engineer - Austin, Texas, United States

Originally posted 28 July 2026 by the employer.

This role focuses on designing safe, resilient, and scalable electrical infrastructure for high-density AI computing environments.

About the role

The Principal Electrical Engineer will lead the architecture and delivery of safe, resilient, and scalable electrical infrastructure for high-density AI computing environments. This role will guide projects from early technical studies through design, construction, commissioning, operation, and lifecycle improvement.

What you'll do

• Act as the technical authority for electrical engineering across data center infrastructure projects, from the utility or on-site power source through to the IT rack.
• Lead electrical architecture development through conceptual studies, detailed design, construction, commissioning, operation, and lifecycle improvement.
• Develop electrical standards, specifications, reference designs, qualification plans, and acceptance criteria for power distribution and conversion systems.
• Define electrical protection and safety approaches for AC and DC systems, including fault detection, interruption, isolation, grounding, stored energy, insulation monitoring, lockout, and safe maintenance.
• Develop resilient power solutions for highly dynamic AI and high-performance computing loads, including ride-through, short-duration energy buffering, backup generation, energy storage, and utility interconnection.
• Evaluate established and emerging power conversion, protection, control, and energy-storage technologies, making clear recommendations based on safety, reliability, efficiency, and maintainability.

What you'll need

• Bachelor’s or master’s degree in Electrical Engineering, a closely related discipline, or equivalent relevant experience.
• Substantial experience delivering mission-critical electrical infrastructure in hyperscale data centers, colocation facilities, semiconductor facilities, utilities, or comparable high-availability environments.
• Demonstrated ability to lead a significant technical area, make independent engineering decisions, and influence outcomes across multiple disciplines and external partners.
• Deep knowledge of medium- and low-voltage AC systems and high-power DC distribution systems.
• Strong understanding of power electronics and conversion technologies, including rectifiers, inverters, isolated and non-isolated DC/DC conversion, controls, and galvanic isolation.
• Strong knowledge of electrical fault behaviour and protection, including grounding, insulation monitoring, selective coordination, interruption, arc hazards, stored energy, and safe maintenance.
