AIEngineer

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. ON.energy is investing in AI as a horizontal capability across the business, from corporate functions to field operations and OT environments. We're standing up a small team to drive adoption, and we're hiring an AI Engineer to build the systems that make it real. You'll partner closely with our Program Manager, AI Enablement, who owns the roadmap and drives adoption across departments. Your job is to ship: prototype quickly, harden what works, and build the technical patterns the rest of the company will reuse. This is a hands-on builder role with high visibility. The CTO is the executive sponsor for AI Enablement, your work will be in front of executives regularly, and the systems you ship will touch most of the company within your first year. Responsibilities Will Include: Building production AI systems end to end, from prototype through deploy and monitor Working directly with stakeholders across Engineering, Operations, HR, Finance, and Commercial to translate workflow problems into shippable tools Writing the evaluation harnesses, prompts, retrieval logic, and integration code that make LLM-powered features reliable Establishing reusable technical patterns: prompt and model governance, eval frameworks, data access, deploy practices Contributing to the technical roadmap, including where to invest, what to kill, and what's worth buil
