Senior Electrical Engineer, Data Centers

The Hyperscale Datacenter Senior Electrical Engineer is the senior electrical authority for ON.energy's presence 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 

• Inform the end-to-end electrical reference architectures for ON.energy products across hyperscale, colocation, enterprise, and AI factory topologies LV and MV distribution, data center substation interfaces, and next-generation 800 Vdc designs.
• Define single-line diagrams, redundancy models, substation interface assumptions, and fault-tolerance strategies for UPS, BESS, PCS, microgrid, and EMS integration.
• Establish and enforce Interface Control Documents (ICDs) between ON.energy 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 ON.energy in industry working groups and codify insights into technology roadmaps. 

Product & Technology Roadmap 

• Inform the architectural roadmap for ON.energy product 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. 

Experience & Requirements

• Education: B.S. in Electrical Engineering, Power Systems Engineering, or related field required. M.S. preferred; PhD acceptable where paired with substantial applied data center electrical design experience.
• Experience: 5+ years in data center electrical systems, mission-critical facilities, hyperscale infrastructure, or A&E engineering serving hyperscale / colocation customers.
• Domain Depth: Hyperscale and colocation electrical topologies from utility service entrance, data center substation design, MV/LV distribution, UPS and BESS integration, redundancy strategy, fault isolation, and server rack PDU interface requirements. 

Preferred Experience

• Architected power delivery for AI training clusters (>100 kW / rack, liquid-cooled, coincident load dynamics).
• Prior work as a hyperscaler owner's engineer, colocation infrastructure lead, or MEP principal for mission-critical facilities.
• Published contributions to OCP, Uptime, IEEE PES, or CIGRE.
• Professional Engineer (PE) license preferred, especially where paired with hands-on data center, substation, or mission-critical electrical design ownership.
• U.S. Person status, or ability to support DOE / national-lab collaborations where U.S. Person eligibility is required.
