Principal/Senior Engineer – MV DC-DC Power Conversion

We are recruiting on behalf of a leading global technology organisation for a Principal/Senior Engineer – MV DC-DC Power Conversion to lead the development of high-power medium-voltage DC-DC conversion technologies for applications including data centres, renewable energy, energy storage and EV charging.

Key Responsibilities

• Develop technical roadmaps for MV DC-DC power conversion within 10kV–35kV Solid-State Transformer (SST) systems.

• Lead architecture design, simulation and development of high-power isolated DC-DC converters using DAB, LLC and CLLC topologies.

• Lead Medium-Frequency Transformer (MFT) design, addressing insulation, partial discharge and thermal management challenges.

• Drive R&D innovation and collaborate with leading research institutes and universities.

• Provide technical support throughout strategic customer projects, including prototypes, testing and on-site technical consultation.

Key Requirements

• 5–8+ years’ relevant industry experience in medium-voltage power conversion, SST or related technologies.

• Strong expertise in SST and MV high-power isolated DC-DC converters.

• Proven knowledge of DAB, LLC and CLLC topologies and control strategies.

• Strong experience with Medium-Frequency Transformer design, high-voltage/high-frequency insulation and partial discharge suppression.

• Experience with high-voltage SiC devices, gate driver design and series voltage balancing.

• Proven experience across the full hardware development lifecycle and project management.

• Strong proficiency in PLECS and experience with electric and magnetic field simulation.

• Experience developing 6kV, 10kV or 35kV SST systems is highly desirable.

• Strong analytical, technical leadership and problem-solving skills.

What’s on Offer

• Opportunity to lead the development of next-generation medium-voltage power conversion technology.

• Exposure to high-impact applications across data centres, renewable energy, energy storage and EV infrastructure.

• Collaboration with leading international research organisations and universities.

• Opportunity to influence technology roadmaps and commercial product development.

• Technical responsibility within an innovative and growing global organisation.
