Senior Traction Power Supply (TPS) Engineer

Joining Arup  

Arup’s purpose, shared values, and collaborative approach has set us apart for over 75 years, guiding how we shape a better world. 

This role is responsible for the planning, design, analysis, integration, and technical assurance of rail traction power supply and distribution systems (AC and DC) for metro, light rail, commuter rail, and electrified mainline rail projects. The engineer translates operational requirements and client standards into safe, reliable, maintainable, and cost-effective traction power solutions, coordinating closely with multidisciplinary teams through concept, preliminary, detailed design, construction support, testing, and commissioning.

This job posting represents an active vacancy within our organization and is open for immediate recruitment.

The opportunity  

• Develop traction power supply and distribution concepts and basis-of-design documents (system voltage, feeding philosophy, substation spacing, redundancy, return circuit, negative bonding, and operational switching).
• Perform and/or review power system studies: traction load flow, voltage drop, short-circuit and ground-fault analysis, power quality/harmonics, power factor, and protection coordination/selectivity.
• Design traction power substations, paralleling/switching stations, sectioning and paralleling arrangements, feeder cables, return/negative circuits, and associated interfaces to utility supply.
• Develop earthing/grounding, bonding, and stray current control designs; carry out step-and-touch potential calculations and soil resistivity interpretation; coordinate mitigation measures with civil/track/structures.
• Produce deliverables including single line diagrams, schematics, wiring diagrams, cable schedules, equipment layouts, routing plans, bills of materials/quantities, and technical specifications.
• Define functional requirements for remote power control and traction power SCADA (RTUs/PLCs, I/O lists, communications, alarm philosophy); support factory/site acceptance testing and commissioning.
• Coordinate multidisciplinary interfaces (OCS/third rail, track, signaling, telecom, stations, structures, fire/life safety, and systems integration) and resolve technical conflicts and constructability issues.
• Provide technical assurance: independent checking of calculations and drawings, compliance with client/authority standards and applicable codes, and participation in design reviews and hazard/risk workshops.
• Support construction through responses to RFIs, review of shop drawings, site inspections, punchlisting, and as-built documentation; investigate field issues and propose corrective actions.
• Contribute to proposals and bids: scope definition, assumptions/constraints, programme inputs, risk/opportunity identification, and technical writing.

You will have the opportunity to do socially useful work that has meaning – to Arup, to your career, to our members and to the clients and communities we serve.  

Is this role right for you?

• Bachelor’s degree in Electrical Engineering (or equivalent); Master’s degree is an asset.
• Professional Engineer (P.Eng.) eligibility/registration (as applicable to jurisdiction).
• Experience delivering traction power supply & distribution designs across project phases (typ. 5+ years for intermediate; 8–12+ for senior, depending on role level).
