About IONATE
IONATE is a deep‑tech scale‑up building the hardware and software backbone for smart grids. Our mission is to transform power systems – from grids and microgrids to renewables and data centres – unlocking the massive potential in this under‑innovated sector that touches every aspect of our modern lives.
We are now looking for an Electronics Engineer to join our Power Electronics team. Requiring knowledge and experience in electronics development and design, you will play a key role in the development, design, implementation and testing of electronics circuits and systems, taking concepts and prototypes through to commercial products.
What you will do
 * Contribute to the development of high‑power converters and controllers for grid‑connected applications.
 * Design, simulate, implement, test, verify and troubleshoot electronic hardware, circuitry and components used for power converters, controllers and auxiliary hardware.
 * Develop high‑reliability PCB assemblies, suitable for high‑volume production.
 * Contribute to build and test efforts, including electrical panel assemblies, wiring looms, soldering and PCB rework.
 * Actively participate in technical development and testing across a multi‑disciplinary team including power electronics designers, mechanical engineers, control & software engineers.
 * Be involved hands‑on with hardware design and validation respecting safety, quality and international standards, whilst working to clear timelines.
 * Work to clear timescales and collaborate with a cross‑functional team to deliver projects on time, with ambitious product targets.
 * Create and maintain documentation such as requirements, design descriptions, testing plans and testing reports.
What you will need
 * Degree in Electrical and Electronics engineering or equivalent.
 * Experience in electronics design, ideally in high power applications.
 * Good understanding of electronic and electrical components and their principles.
 * Good understanding of signal processing and passive/active filter designs.
Design, Modelling & Simulation
 * Experience in electronics circuit modelling and simulation.
 * Experience using tools including SPICE, Altium, MATLAB.
Testing & Validation
 * Experience conducting laboratory and site‑based testing using test equipment such as oscilloscopes, power supplies, load banks.
Collaboration & Communication
 * Communication skills enabling you to work with various teams across the globe.
 * Willingness to travel nationally and internationally when required for testing/commissioning.
 * A drive to learn new things.
It would be useful to have
 * Experience in power electronics converters (AC/DC, DC/AC, DC/DC).
 * Design experience for low noise, mixed signal systems.
 * An understanding of best practices related to thermomechanical design.
 * Experience designing systems to meet EMC/EMI standards and testing commercially ready systems for UL/TUV certification.
 * Testing experience working with voltages up to 1kV.
 * Experience designing systems fit for large scale manufacturing and production.
Benefits
 * Employee Option Plan – equity in IONATE.
 * Private Medical & Dental Insurance – full cover through Bupa.
 * Company pension – flexible, sustainable pension product.
 * Career Development – annual budget for professional development.
 * Flexible working schedules – work‑from‑home arrangements.
 * Cycle to Work Scheme – low‑carbon travel bicycle purchase scheme.
 * Slow travel – extra 2 slow travel days per year.
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.
Equal Opportunity
We are 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.
