Sourcing Manager - Transformers at ON.energy

<div class="content-intro"><p>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.</p></div><h3 data-section-id="colne8" data-start="176" data-end="219"><strong data-start="180" data-end="219">Supply Chain Manager – Transformers</strong></h3> <p data-start="221" data-end="624">The Supply Chain Sourcing Manager – Transformers is responsible for planning, sourcing, purchasing, logistics, and supplier management across transformer and substation equipment.
