On.Energy is a Miami-headquartered independent power producer that develops, integrates and operates AI-driven battery energy storage systems across the Americas.
<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><p data-start="181" data-end="394">We are seeking a <strong data-start="198" data-end="244">AWS Cloud / DevOps / Platform Engineer</strong> who can operate with a high degree of ownership and independence while contributing to the design, build, and operation of scalable AWS environments.</p> <p data-start="396" data-end="752">This role is suited for early-career engineers who already have hands-on AWS experience and are ready to take on more responsibility in managing cloud infrastructure end-to-end.
