Full-time, hybrid with London office base - 3 days-per-week
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 datacentres – unlocking the massive potential in this under-innovated sector that touches every aspect of our modern lives.
We are now looking for a Power 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.
With a focus on grid-connected inverter design, you will be actively contributing to analyses, design reviews, simulations, technical discussions, verification and validation processes. Importantly, you will be contributing to live, ongoing projects and test activities, as well as closely working with the team to continue developing our HIT technology.
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.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
