The ideal candidate will have 5+ years of electrical engineering experience, with experience in traction power, rail/transit electrical systems, or comparable medium- and high-power electrical infrastructure. This position will work closely with multidisciplinary engineering teams to develop reliable, safe, and maintainable power systems supporting transit operations.

• Support the design and engineering of traction power systems for light rail, heavy rail, commuter rail, and other transit applications.
• Develop and review traction power system designs including traction power substations, DC distribution systems, AC power distribution, switch gear, transformers, rectifiers, circuit breakers, protective devices, grounding, and associated equipment.
• Perform or support traction power load flow, voltage drop, short-circuit, grounding, and system performance analyses.
• Prepare engineering calculations, technical specifications, design criteria, reports, drawings, single-line diagrams, equipment layouts, site plans, and other design documentation.
• Support the development of traction power designs through various project phases, including conceptual, preliminary, final design, construction, testing, and commissioning.
• Coordinate traction power requirements and interfaces with other rail systems, including OCS/catenary, signals, communications, track, facilities, utilities, vehicles, and civil/structural disciplines.
• Review vendor and contractor submittals, shop drawings, technical data, and requests for information.
• Assist with equipment selection and technical evaluation of traction power equipment and components.
• Support system interface definition and resolution of multidisciplinary design issues.
• Participate in design reviews, technical meetings, constructability reviews, and project coordination meetings.
• Provide engineering support during construction, installation, testing, commissioning, and system integration activities as required.
• Perform field investigations, site assessments, and inspections of existing traction power facilities and equipment.
• Support the preparation of technical proposals, scopes of work, schedules, estimates, and other project documentation.
• Ensure designs comply with applicable client requirements, project criteria, codes, standards, and industry practices.

• Bachelor’s degree in Electrical Engineering or a closely related engineering discipline.
• 10+ years of relevant electrical engineering experience, preferably involving traction power, rail/transit systems, substations, power distribution, or comparable electrical infrastructure.
• Working knowledge of electrical power distribution principles, equipment, protection, grounding, and electrical system design.
• Experience preparing or reviewing engineering calculations, drawings, specifications, and technical reports.
• Ability to interpret electrical single-line diagrams, schematics, wiring diagrams, equipment layouts, and construction documents.
• Experience coordinating electrical designs with multidisciplinary engineering teams.
• Strong technical problem-solving and analytical skills.
• Strong written and verbal communication skills.
• Ability to effectively manage technical assignments, priorities, and deliverables in a multidisciplinary project environment.

• Direct experience designing traction power systems for light rail, heavy rail, commuter rail, or other electrified transportation systems.
