It integrates into the network like a transformer but solves key power quality issues through all-in-one power flow control. Beyond the passive voltage step, it provides data visibility, stepless and dynamic voltage control, harmonics removal and reactive power control with millisecond-precision. Its innovative hybrid design leveraging magnetic control makes it a robust, reliable, and affordable upgrade.While deployed to remove constraints and prevent issues, HITs effectively light up real-time control nodes for the very first time. Once placed in strategic points of the network, IONATE’s AI platform can coordinate them to form a true smart system, coupling top-down grid orchestration with instantaneous bottom-up control in the physics. This full stack will achieve real-time system optimisation and turn the passive old grid into a flexible, decentralized platform that catalyses innovation. <h3>3 reasons why you should apply:</h3>You’ll work on something that matters. The most rewarding aspect of our job is seeing what we build in the lab get used in the real world. As our tech gets used in solar farms, batteries, and electricity grids, your work will help shape the future of the green energy transition.​The thinking you’ll do here is not your average exercises on repeat. Building a brand-new class of tech requires cutting-edge ideas. If you like to solve unconventional problems, to be given freedom to explore, to challenge – and be challenged by – field experts, you will fit just right in.​The rocket ship is taking off. Our innovation has been proven and demand is immense. IONATE is now rapidly scaling up and undertaking global projects. Joining early and working side-by-side with our leadership team means ample opportunity to grow your role together with our company. IONATE has a friendly team that collaborates and supports one-another. If you don’t fit all the description above, but you are passionate about the work we are doing and could add value to our team, please get in touch. We believe in making positions fit the skills of people, not the other way around. We are also committed to providing equal opportunities, an inclusive work environment, and fairness for everyone. We value diversity in race, gender identity, sexuality, age, family or civil status, disability, religion, or ethnicity and encourage you to apply wherever you come from.
