Job summary

Hitachi Energy Ltd. is seeking an R&D Electrical Engineer to lead circuit-level, electromagnetic, and multi-physics simulations for dry-type and liquid-filled distribution and traction transformers.

You will work with a global team to accelerate product development while validating designs with simulation-driven methods. Ideal candidates hold an advanced degree in EE, have strong FEA and scripting skills, and can contribute to innovative workflows.

Qualifications

• M.Sc. or Ph.D. in Electrical Engineering.
• Professional experience in electrical engineering; transformer design is highly valued.
• Strong knowledge of circuit theory, electromagnetics, and transformer physics.
• Experience with electromagnetic finite element analysis (FEA) tools such as ANSYS Maxwell, COMSOL Multiphysics, Altair Flux, FEMM, or similar.
• Knowledge of simulation and programming tools such as LTspice, PSpice, PowerFactory, ETAP, Python, MATLAB, or C#.
• Strong analytical, communication, and collaboration skills, with the ability to work effectively in a global environment and travel as needed.

Responsibilities

• Perform circuit-level, electromagnetic, and multi-physics simulations for transformers.
• Analyze transformer performance, including losses, impedance, leakage fields, transient behavior, inductances, and short-circuit forces.
• Support simulation-driven product development strategies that enable early design validation and prediction of factory test results.
• Develop and maintain automated simulation workflows and engineering tools to improve efficiency and accuracy.
• Advance innovative multi-physics methodologies by integrating electrical, structural, thermomechanical, and acoustic simulations.
• Contribute to feasibility studies, technology assessments, and the development of new products and technical concepts.
• Support prototype validation and testing activities to verify simulation models and enhance product performance.
• Share technical expertise through design guidelines, internal training, and close collaboration with engineering and design teams.
