What you will do:
Power Electronics Design & Development
- Lead the architecture, design, and development of advanced power electronics systems for grid-connected applications.
- Design, prototype, and validate power conversion systems (AC-DC, DC-DC, AC-AC), including high-frequency and high-power topologies.
- Develop mixed-signal circuits, including but not limited ADC sensing chains, PWM control, and gate driver for high-performance converters.
- Oversee and contribute to PCB design and layout, with strong emphasis on signal integrity, power density, and manufacturability.
- Lead EMI/EMC design and compliance activities, ensuring products meet relevant regulatory standards for grid-connected equipment.
- Lead system level validation strategies, including test planning, verification, and certification activities.
- Take ownership of hardware design from concept to production, ensuring compliance with safety, quality, and international standards.
- Act as the Technical Lead for key power electronics development, defining system architecture, key technology choices or trade-offs, and validation plans.
- Drive design decisions across converter topologies, control strategies, magnetics, and system integration.
- Lead technical reviews, mentor engineers, and set best practices across power electronics activities.
- Create and maintain high-quality engineering documentation, including system requirements, design specification, technical analysis, and testing reports.
- Support external communications by contributing to technical presentations, product documentation, and customer-facing materials.
- Ensure adherence to relevant industry standards and internal engineering processes.
What will you need:
- Degree in Electrical & Electronic Engineering, Power Electronics, (or equivalent), with extensive experience in end-to-end product development - from concept through to commercialisation.
- Strong track record in designing and delivering high-voltage, high-power power electronics converters.
- Deep understanding of advanced converter topologies such as CHB, LLC, DAB, MMC, and their application(s) in grid-connected systems.
- Proven expertise in power electronics design, including component selection, magnetics, control interfaces, and system-level integration.
- Experience with circuit modelling, simulation and PCB design, using tools such as SPICE, MATLAB/Simulink, and Altium (or equivalent).
- Experience designing and testing high-voltage power electronics systems, such as Power Conversion Systems (PCS), EV chargers, Solid-State Transformer (SST), HVDC/STATCOM, or Medium-voltage VFD (Variable Frequency Drive).
- Experience designing systems to meet EMC/EMI compliance requirements.
- Experience designing and testing commercially-ready systems for CE/UL/TUV certification, including working with external certification bodies.
- Familiarity with system-level control of grid-connected converters, including grid synchronisation, protection, and stability considerations.
- Background in volume manufacturing environments, including design for cost optimisation, yield improvement, and supplier engagement.
- Understanding of energy systems applications such as DC-grid, renewable integration, or energy storage systems.
- 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.
