Remove blockers and act fast to resolve issues across the teams to ensure smooth delivery of projects. Project Execution and Management Ensure that projects are delivered in scope, on time and within budget working in tandem with the project manager. Be involved customer, supplier and partners facing conversations at each stage of the project ensuring technical alignment. Monitor project status, report technical and schedule progress, and anticipate issues to inform risk management reviews and decisions. Participate in supplier evaluations, logistics, procurement, and quality assurance for critical components. Site-Based Engineering and Travel Traveling nationwide or internationally, at times on short notice to customer, partner, supplier and test sites for surveys, testing, installations and onboardings. Conduct site surveys and work with customers to integrate start-up solutions into their operations, adapting quickly to project scope changes. Perform functional and acceptance testing, commissioning, installations, and post-delivery troubleshooting across all projects. Collecting field data and lessons learned to inform incremental improvements to improve design and support future product development. Requirements Bachelor’s or Master’s degree in Electronics, Electrical, Power Electronics or Mechatronics Engineering. Experience with transformers, high power/grid connected inverters, substation design or any grid interfaced/high power-power electronics hardware product is highly valued. Demonstrated experience traveling for site-based project work for site surveys, SAT, FAT, installation and commissioning is a must. Proficient in technical project management, cross-functional collaboration and utilising tools such as Confluence, JIRA, MS Projects, AutoCAD and SAP. Strong verbal and written communication skills for both technical and non-technical audiences. Comfortable working independently with minimal supervision and willing to travel extensively as required. Familiarity with commissioning, safety standards, and onsite troubleshooting, especially in hardware-heavy environments.

About IONATE Driven by first-principles engineering, IONATE is transforming power systems for the energy transition. Our hardware is the Hybrid Intelligent Transformer (HIT): a new building block for the power grid and everything connecting. 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. 3 reasons why you should apply: 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.
