Electronics Engineer

IONATE
London
Salary: £55,000 - £65,000

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 data centers - 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.

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 and 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.
Requirements

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 etc.
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

Your benefits:
  • Employee Option Plan: You get equity in IONATE, so as we succeed so do you.
  • Private Medical & Dental Insurance: From day one, we provide you with full, comprehensive private medical and dental cover through Bupa. You also have the option to add any dependents to your cover. Please ask us for more details.
  • Company pension: a flexible, and sustainable pension product to help you plan for your future.
  • Career Development: It's important to us that you have the opportunity for ongoing professional development and career growth. You will receive an annual budget for professional development and work with your team to set and reach goals every year.
  • Flexible working schedules: You will have the flexibility for work-from-home arrangements. Talk to us at the application stage about this.
  • Cycle to Work Scheme: Low carbon travel is important for everyone, so we have in place a cycle scheme to help you purchase a bicycle.
  • Slow travel: We believe in a low carbon future, so if you wish to travel by a lower carbon method - but it takes much longer than flying - we will give you an extra 2 slow travel days per year.
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. 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.
