Principal/Senior Engineer - MV DC-DC Power Conversion (m/f/d)

Your mission

Technology Planning:
Align with industry trends and customer demands across data centers, PV, energy storage, and EV charging sectors to formulate technical roadmaps for the DC-DC power conversion subsystem within 10kV–35kV medium-voltage direct-connected Solid-State Transformers (SST), ensuring superior competitiveness of product solutions.

Core Technology R&D:
Lead the architecture design, simulation modeling, and key component design of medium-voltage high-power isolated DC-DC converters (topologies including DAB, LLC, CLLC), and take full accountability for the competitiveness of R&D deliverables. Lead the design of Medium-Frequency Transformers (MFT), and tackle technical challenges such as insulation design under medium-voltage high-frequency operating conditions, partial discharge (PD) suppression, and thermal management under complex working conditions.

Technology Insight & Collaboration:
Track cutting-edge technologies of medium-voltage high-power isolated DC-DC converters to identify innovation opportunities; cooperate with top industrial research institutes and universities to incubate new technologies and facilitate technology transfer and mass deployment.

Technical Support for Key Projects:
Provide end-to-end technical support for frontline sales in strategic project development, prototype testing, and on-site technical consultation to drive successful closure of key customer projects.

Your areas of expertise

Professional Expertise:
Seasoned specialist in Solid-State Transformers (SST) and medium-voltage high-power isolated DC-DC conversion. Proficient in topologies including DAB, LLC and CLLC as well as their control schemes; well-versed in Medium-Frequency Transformer (MFT) design, high-voltage high-frequency insulation and partial discharge suppression. In-depth research and hands-on development experience in high-voltage SiC device application, gate driver design, and series voltage balancing control.

Core Business Competency:
Skilled in the full hardware development workflow for medium-voltage high-power converters with proven project management capabilities.

Simulation Tools Proficiency:
Expertise in PLECS simulation software; capable of conducting electric field and magnetic field simulations to analyze electric field strength for medium-voltage insulation design.

Professional Experience:
Minimum 5–8 years of relevant industry experience. Candidates with proven successful development experience of medium-voltage (6kV/10kV/35kV) SST are highly preferred.
