Job description

The Opportunity:

Our R&D engineers and scientists develop breakthrough technologies that change the way the world works, and industries do business. We constantly push the limits of convention, while retaining our focus on delivering quality products and solutions to our customers.

Power Electronics in Hitachi Energy has over 100 years of history, it’s started from development and manufacturing of Mercury-Arc Valves; introduction of breakthrough technologies like HVDC; pioneering power semiconductor manufacturing; bringing electricity to transportation; and enabling Smarter, Stronger and Greener Power Grids.

Hitachi Energy has committed to Net-Zero in the 2050 strategy, focusing R&D development to deliver technologies which support achieving The Carbon-Neutral Future. The backbone for the grid transformation is Power Electronics, where we are developing new efficient solutions for: integrating renewables, providing energy storage, improving power quality, and enabling green transportation & eMobilty solutions.

The Power Electronics team has being established in Krakow in 2021, as part of this team, you will be working in a small, cross-functional team of highly skilled engineers consisting of Power Electronics, Control Engineers, HW Electronics and Mechanical Engineers. You will develop a new breakthrough modular converter platform based on wide bandgap semiconductors (e.g. SiC) for a range of grid and DC applications. You are expected to push the technology boundaries in terms of efficiency, size and operational performance. If you are ready for the challenge, then join us.

You will cooperate with global R&D teams, in case of technical questions you will get direct support from Simon Round Corporate Executive Engineer – Power Electronics & Digital. A creative environment allows you to utilize your knowledge and skills in technology and product development to identify and implement innovative solutions for a new Product Platform.

How you'll make an impact:

• Be part of the design process for our future converters technology and other power electronic sub-systems and take a leading role to take new ideas from idea generation through simulation, circuit design, prototyping all the way to verification.
• Take responsibility for specification, selection, qualification and verification of semiconductors, passive component and protection concepts.
• Contribute to feasibility studies on converter topologies, while gaining knowledge on Power Grids applications and requirements.
• Support a fast, iterative design process in a cross-functional, dedicated team. Use fast prototyping and lab mockups to close learning loops and achieve results quickly.
• Build up and maintain measurement and test setups to verify performance, efficiency and robustness.
• Contribute to solving technical challenges related to EMC/EMI, thermal management & safety.
• We offer an exciting job in an international environment where you will get great possibilities to develop further within Hitachi Energy.
