The OpportunityWe are looking for a Junior R&D Electrical Engineer to join our Global Multi-physics Simulation Team within the Transformers business. In this role, you will support the development of advanced dry-type and liquid-filled distribution and traction transformers by performing circuit-level, electromagnetic, and multi-physics simulations.
You will work in a global, cross-functional R&D environment with strong interaction with engineering, testing, and product development teams, contributing to a shift-left approach where simulations are used to predict product performance early in the development cycle and anticipate factory test results.
How you'll make an impact:- Perform circuit-level, electromagnetic, and multiphysics simulations of all typical performance measures of dry-type and liquid-filled distribution and traction transformers, in accordance 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.
Your background- M.Sc. in Electrical Engineering.
- Initial professional experience in electrical engineering, preferably with exposure to transformer design, is an advantage.
- Strong theoretical foundation in circuit theory, electromagnetics, and transformer physics for dry-type and liquid-filled distribution and traction transformers.
- 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.
