R&D Electrical Engineer for Global Multi-physics Simulation Team

Hitachi Energy

Łódź, Poland

#JID3-190159

Position summary

ordance with relevant international standards (e.g. IEC, IEEE).

  • Evaluate transformer performance parameters such as losses, impedance, leakage fields, short-circuit forces, inductances, and transient behavior using circuit-level and electromagnetic finite-element (FEM) simulations.

  • Apply circuit-level, electromagnetic, and multi-physics simulations to support a shift-left development strategy, aiming to predict the outcome of Factory Acceptance Tests early in the design phase and reduce design iterations, testing effort, and development risk for dry-type and liquid-filled distribution and traction transformers.

  • Develop and maintain automation tools and simulation workflows for circuit-level, electromagnetic, and multiphysics simulations, explicitly focused on early design validation and FAT prediction.

  • Develop new multi-physics simulation methodologies by coupling circuit-level and electromagnetic models with: Structural mechanics simulations, Thermomechanical simulations, Acoustic simulations

  • Support feasibility studies, development of new technical concepts, and simulation-based assessment of new technologies and product variants related to dry-type and liquid-filled distribution and traction transformers.

  • Contribute to the design and performance prediction of dry-type and liquid-filled distribution and traction transformers.

  • Support and organize prototyping and testing activities to validate simulation models and new technologies.

  • Support product and technology development projects, contributing to delivery in line with agreed scope, time, cost, and quality.

  • Support the transfer of technology and know-how from R&D to Engineering by:, Writing design rules and technical guidelines, Preparing and delivering internal technical trainings, Collaborating closely with design tools and engineering teams

  • Provide technical support to other departments (Engineering, Product Management, Marketing, Sales) when required.

  • Preferred: knowledge of transformer performance prediction, including: Impedance and transient behavior, Leakage fields, Stray and no-load losses, Short-circuit forces, Mutual inductances and related parameters

  • Preferred: experience with electromagnetic finite element analysis (FEA) using one or more tools such as: ANSYS Maxwell, COMSOL Multiphysics, Altair Flux, FEMM, other EM FEM-based tools

  • Preferred: experience or familiarity with circuit-level simulation tools, such as: LTspice, PSpice, Ansys TwinBuilder/Simplorer or equivalent circuit simulation environment

  • Knowledge of at least one programming language:, Python, MATLAB, C#

  • Exposure to or interest in electrical testing of dry-type and liquid-filled distribution and traction transformers is an advantage.

  • Basic project management capabilities and willingness to take ownership of tasks.

  • Action- and results-oriented mindset combined with strong analytical skills.

  • Innovative spirit and motivation to apply simulation-driven, "out-of-the-box" approaches.

  • Fluent in English, both written and spoken.
