1d•$120,000 - $200,000•Onsite

About The Position

AECOM is seeking a Project Engineer, Traction Power and Medium Voltage, for an on-site role in Sacramento, California. The position provides engineering leadership for traction power, medium voltage distribution, and auxiliary power systems on a major transportation infrastructure project. Systems include 25kV AC traction power, 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. The role spans design, procurement, construction, testing and commissioning, energization, and operational handover. It involves reviewing studies, protection schemes, equipment specifications, construction packages, contractor submittals, calculations, and test procedures, while coordinating interfaces across electrical, railway, civil, operations, and maintenance disciplines. The position supports field installation, testing, commissioning, and energization activities, with approximately 25–50% travel along the project alignment throughout California’s Central Valley.
