Senior Electrical Engineer, Data Centers

is building the backbone of energy and AI infrastructure powering grid-safe data centers and mission-critical facilities. The company supplies and operates hyperscale power systems that solve the toughest resilience challenges delivering custom solutions for AI data centers mission-critical facilities and front-of-the-meter assets. ON recently announced a 5GW partnership with 3GW currently under construction across multiple hyperscale data center campuses. With patented technology and proprietary softwaredevelops projects worldwide that set new benchmarks for resilience.

The Hyperscale Datacenter Senior Electrical Engineer is the senior electrical authority forpresence at hyperscale colocation enterprise and AI-focused data centers. This role is focused on data center electrical engineering while maintaining utility-interface fluency to translate customer operator substation and site-infrastructure requirements into deployable product requirements interfaces and reference electrical designs.

Key Responsibilities

Reference Architectures & System Definition

• Establish and enforce Interface Control Documents (ICDs) between equipment and upstream utility downstream IT load and site controls.

Requirements Engineering

• Own the requirements traceability matrix from customer SOW to system architecture to subsystem to component test.
• Define compliance boundaries against applicable standards such as TIA-942 ASHRAE TC 9.9 and IEC 62040.

Customer & Ecosystem Engagement

• Act as the technical face to hyperscale colocation and AI infrastructure customers throughout new product development.
• Lead architecture reviews with project engineering teams data center operators and chip / server OEMs.
• Represent in industry workinggroups andcodify insights intotechnologyroadmaps.

Product & Technology Roadmap

• Inform the architectural roadmap forproduct architectures.
• Evaluate emerging DC power distribution solid-state transformer and grid-interactive architectures; recommend build / buy / partner strategies.
• Own vendor evaluation and technology partner scorecards from a systems-fit perspective.
