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.
The UX/UI Designer is responsible for the design, prototyping, and front-end development of SCADA products and automation interfaces that ensure a seamless and intuitive experience for operators and engineers managing energy storage systems. This role bridges aesthetic design, user research, and technical front-end implementation, working to transform complex system data and stakeholder feedback into high-performance, responsive, and scalable visual solutions.
