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><strong><span data-contrast="auto"><span data-ccp-parastyle="heading 10" data-ccp-parastyle-defn="{"ObjectId":"81d40c56-e640-5cda-82bb-83448542e906|1","ClassId":1073872969,"Properties":[469775450,"heading 10",201340122,"2",134234082,"true",134233614,"true",469778129,"heading10",335572020,"1",134224900,"true",335551500,"7949855",268442635,"36",335559739,"40",335560102,"0",469777841,"Arial",469777842,"Arial",469777843,"Arial",469777844,"Arial",469769226,"Arial"]}">Senior Commissioning Engineer</span></span></strong><span data-ccp-props="{"335559739":40}"> </span></p> <p><em><span data-contrast="auto">Project Site Lead — Mission-Critical Power & Energy Storage</span></em><span data-ccp-props="{"335559739":160,"335572079":6,"335572080":6,"335572081":7949855,"469789806":"single"}"> </span></p> <p><strong><span data-contrast="auto">Location: </span></strong><span data-contrast="auto">Field-Based / Remote in United States (with travel to active project sites)</span><span data-ccp-props="{"335559739":40}"> </span></p> <p><strong><span data-contrast="auto">Travel Requirement: </span></strong><span data-contrast="auto">~80%</span><span data-ccp-props="{"335559739":40}"> </span></p> <p><strong><span data-contrast="auto">Position Type: </span></strong><span data-contrast="auto">Full-Time, Hourly (Non-exempt, eligible for OT) + GSA Rate per diem eligible while traveling</span><span data-ccp-props="{"335559739":40}"> + </span></p> <p><strong><span data-contrast="auto">Reports To: Senior </span></strong><span data-contrast="auto">Commissioning Manager</span><span data-ccp-props="{"335559739":40}"> </span></p> <p><span data-contrast="auto">ON.energy is building the power infrastructure that makes the AI era possible.
