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><span data-contrast="none">We’re looking for a Principal Power Electronics Engineer to set the technical direction for the grid-connected inverters at the heart of ON.energy’s AI UPS product family. This is the senior technical voice for power electronics on the product team: you architect the converter and controls approach, resolve the hardest engineering trade-offs, set the engineering standards others work to, and represent ON.energy’s inverter engineering externally — to vendors, customers, certifying bodies, and the broader industry. You are fluent in power electronics, its controls (grid-following and grid-forming), and BESS integration — ideally with UPS experience in mission-critical applications — and you own the inverter technical thread from proposal through FAT, commissioning, and field feedback for MW-scale systems.</span><span data-ccp-props="{"201341983":0,"335559738":0,"335559739":80,"335559740":250}"> <br><br></span></p> <p><strong><span data-contrast="none"><span data-ccp-parastyle="heading 10">Key Responsibilities</span></span></strong><span data-ccp-props="{"335559738":200,"335559739":70,"335572079":6,"335572080":0,"335572081":1307647,"469789806":"single"}"> </span></p> <p><strong><span data-contrast="none">Architecture & technical authority</span></strong><span data-ccp-props="{"335559738":120,"335559739":50}"> </span></p> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335551500":1710618,"335552541":1,"335559685":320,"335559991":220,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1"><span data-contrast="none">Own the grid-connected-inverter product architecture and converter-controls strategy — grid-following and grid-forming operation, current limiting, and dynamic grid support — and the technical roadmap across concurrent product cycles.</span><span data-ccp-props="{"201341983":0,"335559739":40,"335559740":240}"> </span></li> </ul> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335551500":1710618,"335552541":1,"335559685":320,"335559991":220,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="2" data-aria-level="1"><span data-contrast="none">Define the engineering standards, design rules, and review gates the team works to; act as the final technical authority on the inverter change baseline.</span><span data-ccp-props="{"201341983":0,"335559739":40,"335559740":240}"> </span></li> </ul> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335551500":1710618,"335552541":1,"335559685":320,"335559991":220,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="3" data-aria-level="1"><span data-contrast="none">Serve as the company’s SME for grid-code and UPS performance compliance — IEEE 2800, IEEE 1547, UL 1741, IEC 62040-3, ERCOT ride-through — and set the inverter qualification / type-test program, acceptance criteria, and current-limit / short-circuit and data-evidence requirements suppliers must meet.</span><span data-ccp-props="{"201341983":0,"335559739":40,"335559740":240}"> </span></li> </ul> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335551500":1710618,"335552541":1,"335559685":320,"335559991":220,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="4" data-aria-level="1"><span data-contrast="none">Act as the ultimate escalation point for inverter root-cause analysis (current-limit, post-fault recovery, thermal, control instability) and drive corrective design changes.</span><span data-ccp-props="{"201341983":0,"335559739":40,"335559740":240}"> </span></li> </ul> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335551500":1710618,"335552541":1,"335559685":320,"335559991":220,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="5" data-aria-level="1"><span data-contrast="none">Mentor senior power-electronics, controls, and project engineers to scale the team’s technical capability.</span><span data-ccp-props="{"201341983":0,"335559739":40,"335559740":240}"> </span></li> </ul> <p><strong><span data-contrast="none">Vendor management & supply strategy</span></strong><span data-ccp-props="{"335559738":120,"335559739":50}"> </span></p> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335551500":1710618,"335552541":1,"335559685":320,"335559991":220,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="6" data-aria-level="1"><span data-contrast="none">Own the strategic inverter vendor / OEM relationships and decide their architecture — sole-source vs dual-source, co-development depth, and IP boundaries.</span><span data-ccp-props="{"201341983":0,"335559739":40,"335559740":240}"> </span></li> </ul> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335551500":1710618,"335552541":1,"335559685":320,"335559991":220,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"h
