AECOM is seeking a Project Engineer, Traction Power and Medium Voltage, for one of our offices in Sacramento, Fresno, or Bakersfield, CA. This is an on-site role.
JOB SUMMARY:
The Project Engineer, Traction Power and Medium Voltage, provides engineering leadership for traction power, medium voltage distribution, and auxiliary power systems on a major transportation infrastructure project. The position covers 25kV AC traction power systems, traction power substations, switching and paralleling stations, utility interconnections, SCADA, protective relays, transformers, high and medium voltage switchgear, grounding and bonding, traction return, auxiliary power, wayside distribution, emergency and standby power, UPS systems, and electrical metering and monitoring. Responsibilities include reviewing electrical studies, protection schemes, equipment specifications, construction packages, contractor submittals, calculations, and test procedures while coordinating interfaces with OCS, signaling, communications, SCADA, stations, maintenance facilities, civil works, track, operations, and maintenance. The position supports installation, testing, commissioning, and energization activities, with travel of approximately 25–50% along the project alignment throughout the Central Valley, California.
JOB RESPONSIBILITIES:
- Lead engineering coordination and technical oversight for traction power, medium voltage, and auxiliary power systems throughout design, procurement, construction, testing and commissioning, energization, and operational handover
- Coordinate engineering interfaces between traction power, OCS, signaling, communications, SCADA, stations, maintenance facilities, civil works, track, operations, and maintenance teams
- Lead technical review of traction power studies, protection schemes, load flow analyses, short circuit studies, grounding studies, equipment specifications, construction packages, and design deliverables
- Review contractor submittals, shop drawings, calculation packages, test procedures, and engineering documentation
- Provide engineering support for 25kV AC traction power systems, traction power substations, switching and paralleling stations, utility interconnection facilities, and traction power SCADA systems
- Provide engineering support for protective relay systems, power transformers, high and medium voltage switchgear, grounding and bonding systems, traction return systems, and power monitoring systems
- Provide engineering support for medium voltage distribution networks, station and maintenance facility power, wayside power distribution, ring main units, distribution transformers, motor control centers, emergency and standby power, UPS systems, low voltage distribution, and electrical metering
- Review engineering deliverables associated with substations, cable routes, duct banks, equipment shelters, and corridor-wide distribution infrastructure
- Coordinate electrical power interfaces supporting signaling, communications, train control, station, maintenance facility, security, and operational control center systems
- Support utility coordination for transmission, sub-transmission, and distribution service connections, including service applications, interconnection agreements, load studies, protection coordination reviews, and energization authorizations
- Provide technical support for statutory, regulatory, and Authority Having Jurisdiction approvals, and support preparation of responses to regulator comments, permit conditions, and inspection findings
- Monitor construction of substations, utility interconnections, medium voltage distribution systems, and wayside electrical infrastructure, and conduct field inspections to verify compliance with approved designs and standards
- Support resolution of field issues, design changes, RFIs, utility conflicts, site access constraints, and construction sequencing challenges
- Provide technical leadership for electrical safety, outage planning, energization readiness, commissioning readiness, and operational handover programs
- Support Factory Acceptance Testing, Site Acceptance Testing, System Integration Testing, protective relay testing, transformer testing, switchgear testing, SCADA verification, and trial running
- Support defect resolution, corrective actions, punch-list closure, final system acceptance, revenue service demonstration, and operational readiness
