  • Ensure full compliance with relevant EN, IEC, and IEEE standards, as well as local regulations.
  • Support system integration with OCS (Overhead Contact System), SCADA, protection, and power quality systems.
  • Conduct load flow, short-circuit, and harmonic studies using modern simulation tools.
  • Review and validate design documents, calculations, and single line diagrams.
  • Support tender preparation, cost estimation, and technical evaluation of suppliers.
  • Collaborate with multidisciplinary teams including OCS, SCADA, RAMS, and Civil Interfaces.
  • Provide technical support during installation, testing, and commissioning.

  • Strong understanding of EN standards (EN 50163, EN 50388, EN 50119, EN 50122) and IEC frameworks.
  • Familiarity with power system design software such as ETAP, DIgSILENT PowerFactory, or PSCAD.
  • Excellent command of English (written and spoken).
  • Team-oriented mindset with strong problem-solving and analytical skills.

Preferred Attributes

  • Experience with international HSR projects (Europe, Asia, or the Middle East).
  • Knowledge of renewable integration or energy efficiency measures in traction power.
  • Chartered Engineer or equivalent professional certification.
  • Experience in client interfacing, tendering, or consulting roles.
