Senior Electrical R&D Engineer - Converter Valve

The opportunity
Join the electrical design valve R&D team at Hitachi Energy, where engineers develop next-generation technologies in HVDC (High Voltage Direct Current) transmission. Our work enables electricity to travel over long distances and undersea cables, connecting billions to reliable power.

Our team is part of GI Valve and oversees the development of semiconductor-based HVDC and SVC converter valves. As a Senior Electrical R&D Engineer, this position involves working on key development projects related to power transmission. Responsibilities include ensuring the reliability, safety, and quality of converter valve systems used in HVDC applications. The role also includes developing and implementing reliability strategies, conducting failure analysis, and supporting continuous improvement activities. Collaboration with other teams and projects will be required as business needs change.

In this role, you get a broad network of contacts within Hitachi Energy's global organization and a good insight into how we work in different functions at Hitachi Energy. You will work in an inclusive environment with a team of competent, professional and friendly colleagues who will help you grow with the tasks.

As a Senior R&D Engineer, you will generate, propose, and implement innovative technology solutions.
