About the Job

Requirements

  • Relevant experience of 10–12 years in traction technology for product design and system integration.
  • Knowledge of simulation tools and techniques for power electronics circuits, IEC standards, traction design principles, component sizing, and rolling stock components.
  • Familiarity with analysis and review methodologies.
  • Familiarity with requirements, configuration, and change management tools such as DOORS or similar.
  • Knowledge of power systems, earthing concepts, EMI-EMC protections, and validations according to IEC 61287 and IEC 61377.
  • Willingness to travel as required for a project and collaborate with international colleagues.

Responsibilities

  • Understand customer requirements and develop the electrical system concept at complete-vehicle level and subsystem concepts.
  • Collect external customer and standards requirements, as well as internal rolling-stock requirements, and allocate them to technical teams.
  • Define the architecture and functionalities of traction drive, auxiliary converter, and energy storage systems, including batteries, using external and internal requirements.
  • Derive vehicle-level performance requirements, discuss them with project teams, and assist with optimizing customer requirements.
  • Ensure consistency and compatibility among traction and auxiliary system functions by verifying component specifications and participating in design reviews.
  • Develop working concepts for traction converters, auxiliary converters, traction motors, traction transformers, and batteries, and generate component specifications for vendors.
  • Define high-voltage component specifications and high-voltage architecture, and work with vendors to develop suitable components for locomotives, metro vehicles, and commuter rail.
  • Develop design documentation and obtain design approval from customers.
  • Develop system designs, including clause-by-clause comments, performance simulations using MATLAB, PSIM, Python, Mathcad, Ansys, SABER, or similar tools, power schemes, component specifications, product descriptions or specifications, system block diagrams, and parts lists as required by the customer.
  • Prepare system and part verification and validation specifications, and perform validation in the test lab and on trains.
  • Define and perform train verification strategies in close collaboration with engineering and validation teams.
  • Conduct prototype tests on subsystems and obtain dispatch or design clearance from the customer.
  • Support implementation or updating of the technical portion of the risk mitigation plan with the project technical manager for traction and auxiliary systems.
  • Analyze technical issues and propose solutions during commissioning and the reliability growth phase.
  • Propose quality, cost, and delivery improvements for traction and auxiliary systems.
  • Coordinate with software, brake, circuit engineering, and mechanical teams to develop electrical subsystems and integrate them into the vehicle.
  • Define performance, braking strategy, slip/slide management, harmonic detection, onboard energy storage functions, medium- and low-voltage supply, and load management, including AC/DC calculations.
  • Resolve technical open issues from investigation through modification implementation and problem closure.
  • Participate in continuous competence development and exchange ideas with teams on technological and process topics.

Desired Qualifications

  • Successfully completed a master's degree in electrical engineering.
  • Ability to analyze and learn, and to work with a results-oriented, team-oriented, and quality-oriented approach.
  • Good communication and presentation skills.
