R&D Power Semiconductor Chip Engineer

Contribute to the development of next-generation power semiconductor chips, with a strong focus on silicon power diodes and related device technologies. Support the end-to-end technology and product development cycle, from concept and simulation through to validation and reliability assessment. Apply and further develop TCAD simulation models to understand device behavior and optimize performance, yield, and cost. Collaborate closely with process engineers, characterization and reliability teams, ensuring alignment between design and manufacturability. Take ownership of individual work packages or sub-projects, contributing to overall project goals and timelines. Drive continuous improvement through data-driven analysis, modelling, and optimization approaches. Actively contribute to knowledge sharing within the team and build a strong systems-level understanding of semiconductor devices and processes.

In our R&D; BiMOS semiconductor chip groups at Hitachi Energy Semiconductors, we are developing advanced power semiconductor devices across multiple voltage classes.
