£65-80K - Full-time - London/Hybrid

IONATE is a deep technology start-up building the technology backbone for smart electricity grids. Our team is looking for a Senior Power Electronics Engineer to support our work on game-changing green technology and grow within our world-class team.

This role will suit someone who thrives in a fast-moving, ever-changing environment, where no two days are the same.

Reporting to the Head of Product and requiring extensive knowledge and experience in power electronics development and design, you will play a key role in developing, designing, implementing and testing power 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. You will need an innovative approach to engineering with well-grounded reasoning and experience. Importantly you will contribute to live ongoing projects and test activities and work with the team to continue developing our HIT technology.

Requirements

What you will do:

• Develop power electronics hardware and circuitry for power converters in grid connected applications

• Focusing on systems design, simulation, component selection and testing in a design proving FAT and SAT capacity

• Design, implement, test, verify and troubleshoot power converters, data converters, ADC and PWM systems, thermal power electronics design, EMC/EMI mitigation, PCB design and layout optimization and interfaces to transformers, controllers, filters, electromechanical systems

• Be involved hands-on with hardware design and validation respecting safety, quality, and international standards

• At times take on the role of a systems engineer, ensuring all teams and components are aligned and well-integrated to produce a cohesive product

• Actively participate in technical development and testing across a multi-disciplinary team including transformer designers, power electronics designers, control software engineers

• 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 and specification documents, testing reports and product manuals

What you will need:

• Degree in Electrical and Electronics engineering or equivalent

• Extensive experience in power electronics design, ideally in high power applications

• Experience in electronics circuit modelling and simulation

• HiL and SiL simulations are a plus

• Experience using tools such as SPICE, Altium, MATLAB, Confluence, JIRA

• Good understanding of electronic and electrical components and their principles, integrated circuits and high frequency electronic systems

• Ability to design, create and test PCB boards

• Good understanding of signal processing and passive/active filter designs

• An understanding of best practices related to thermomechanical designs

• Experience conducting laboratory and site-based testing using test equipment such as oscilloscopes, power analysers, grid emulators etc

• Experience designing systems fit for large scale manufacturing and production

• Communication skills enabling you to work with various teams across the globe

• A drive to learn new things!

It would be useful to have:

• Experience in power electronics converters (AC/DC, DC/AC, DC/DC)

• Experience using schematic capture and layout tools

• Design experience for low noise, mixed signal, and HF systems

• Experience designing systems to meet EMC/EMI standards is a plus

• Experience designing and testing commercially ready systems for UL/TUV certification is a plus

• Soldering and PCB rework.

• Willingness to travel nationally and internationally when required for testing/ commissioning

Benefits

• Flexible working schedules: You will be based in our modern West London offices but will have the flexibility for hybrid work-from-home arrangements. Talk to us at the application stage about any scheduling preferences you may have.

• Employee Option Plan: You get equity in IONATE, so as we succeed so do you.

• Company pension: a competitive, 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.

• Cycle to Work and EV scheme: Low carbon travel is important for everyone, so we have in place both cycle and EV schemes to help you purchase a bicycle or electric car.

• 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 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.
