<div class="content-intro">ON.energy is building the power infrastructure that makes the AI era possible. As AI demand surges past what the grid and traditional data centers can support, ON.energy provides a new class of power technology proven at gigawatt scale and trusted by the world’s leading cloud and AI companies. Our systems are already deployed across 2.5 GW of hyper-scale campuses, validated by top U.S. national labs, and certified for grid-safe operation by major utilities. With real products in the field, we’re scaling faster than the grid can, transforming power from a bottleneck into a competitive advantage for the companies building the future.</div>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  <ul> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="1" data-aria-level="1">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. </li> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="1" data-aria-level="1">Define single-line diagrams, redundancy models, substation interface assumptions, and fault-tolerance strategies for UPS, BESS, PCS, microgrid, and EMS integration. </li> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="1" data-aria-level="1">Establish and enforce Interface Control Documents (ICDs) between ON.energy equipment and upstream utility, downstream IT load, and site controls. </li> </ul> Requirements Engineering  <ul> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="4" data-aria-level="1">Own the requirements traceability matrix from customer SOW to system architecture to subsystem to component test. </li> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="4" data-aria-level="1">Define compliance boundaries against applicable standards such as TIA-942, ASHRAE TC 9.9, and IEC 62040. </li> </ul> Customer & Ecosystem Engagement  <ul> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="6" data-aria-level="1">Act as the technical face to hyperscale, colocation, and AI infrastructure customers throughout new product development. </li> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="6" data-aria-level="1">Lead architecture reviews with project engineering teams, data center operators, and chip / server OEMs. </li> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="6" data-aria-level="1">Represent ON.energy in industry working groups and codify insights into technology roadmaps. </li> </ul> Product & Technology Roadmap  <ul> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="9" data-aria-level="1">Inform the architectural roadmap for ON.energy product architectures. </li> <li data-leveltext="" data-font="Symbol" data-listid="5" data-list-defn-props="{"335552541":1,"335559685":360,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"singleLevel"}" data-aria-posinset="9" data-aria-level="1">Evaluate emerging DC power distribution, solid-state transformer, and grid-interactive architectures;
