Medium Voltage Power Electronics Engineer

About the Role

We are looking for a Power Electronics Engineer to take a leading role in the design, development and validation of high-voltage and medium-voltage power converter systems.

You will contribute to advanced R&D projects focused on modular and multilevel converter technologies, developing high-performance and reliable power conversion solutions for grid-connected systems, energy conversion and industrial power electronics applications.

Your Responsibilities

• Converter Design: Lead power converter development from initial concept through detailed design, prototyping and validation.
• Power Electronics Development: Design, model and analyse medium- and high-voltage converters, including Modular Multilevel Converters (MMCs) and other multilevel topologies.
• Component Selection: Select appropriate converter topologies, semiconductor devices and passive components based on performance, efficiency and reliability requirements.
• Modelling & Simulation: Develop electrical and thermal models and perform system-level simulations under various operating and fault conditions.
• Control Systems: Support the development of control and modulation strategies for multilevel converters.
• Digital Control & Firmware: Contribute to firmware and digital control development, with DSP and FPGA experience being advantageous.
• Prototyping & Integration: Support the construction, integration and commissioning of laboratory prototypes and R&D test setups.
• Testing & Validation: Plan and conduct experimental testing, including voltage and current measurements, efficiency assessments and performance validation.
• Technical Analysis: Compare experimental results with simulation models and identify opportunities for improvement.
• Documentation: Prepare technical documentation, design reports and test summaries.
• Collaboration: Work closely with mechanical, control and systems engineers on multidisciplinary projects.

Your Qualifications & Skills

• Degree in Electrical Engineering, Power Electronics or a closely related discipline.
• Professional experience in a similar power electronics engineering role.
• Proven experience developing high-voltage or medium-voltage power converter systems.
• Strong knowledge of multilevel converter topologies, particularly Modular Multilevel Converters (MMCs).
• Hands-on experience with simulation tools such as MATLAB/Simulink, PLECS, LTspice or equivalent.
• Understanding of insulation, grounding, protection and safety requirements in high-voltage systems.
• Experience with digital control platforms, including microcontrollers or DSPs; FPGA experience is a strong advantage.
• Practical experience building and testing power electronics hardware.
• A strong interest in research, innovation and developing advanced engineering solutions.
• Excellent written and verbal communication skills in English. German language skills are advantageous.
