Context

The Traction Power Specialist is responsible for leading the design and technical delivery of the traction power system for the SRS scope, ensuring that substations, distribution, protection, and system interfaces are fully integrated and meet project requirements. The role also supports the full project lifecycle, from design development and technical coordination through construction, testing, commissioning, and safety certification.

Missions/Main Duties

• Lead the design of the traction power system architecture for the SRS scope, including substations, distribution, and protection.
• Define traction power design criteria and performance requirements.
• Oversee the development of engineering studies, including load flow, short-circuit, harmonic, protection, and selectivity studies.
• Coordinate interfaces with the OCS, grounding and bonding, civil/guideway, and hydro/utility providers.
• Review and validate calculations, drawings, and technical specifications.
• Support construction and field installation by providing on-site technical clarifications.
• Witness and support testing activities, including factory, site, and integration testing.
• Provide commissioning oversight, including energization planning and system cutovers.
• Support safety certification activities, including the preparation of technical evidence and coordination with safety assessors.
