• You will bring strong technical expertise, sound design judgment, and a collaborative approach to projects ranging from station upgrades and maintenance facilities to major rail and transit programs.
• The successful candidate will be comfortable taking ownership of communication systems design packages while working closely with engineers, architects, project managers, clients, and other technical disciplines.

Responsibilities

• Lead and perform the design and technical delivery of communications and Operations Technology (OT) systems for complex rail and transit projects.
• Develop communications systems designs from concept through final design, procurement, construction, testing, and commissioning.
• Prepare detailed contract drawings, specifications, calculations, equipment schedules, design narratives, and other technical documentation suitable for construction.
• Design and coordinate a range of transit communications systems, which may include:
• Fiber optic communications networks and infrastructure
• Radio and wireless communications systems
• CCTV and video surveillance systems
• Passenger Information Systems (PIS), including electronic signage and displays
• Computer-Aided Dispatch / Automatic Vehicle Location (CAD/AVL) systems
• SCADA systems, including traction power and train dispatch applications
• Physical Access Control Systems (PACS)
• Video and audio systems, including recording and storage infrastructure
• Communications/server room infrastructure and UPS systems
• Evaluate technical requirements, scopes of work, specifications, design criteria, directive drawings, and applicable standards.
• Develop system architecture, network diagrams, equipment layouts, interconnection diagrams, and detailed design documentation.
• Apply knowledge of networking protocols, network architecture, routers, switches, wireless technologies, and network security principles to transit communications environments.
• Coordinate communications system designs with civil, structural, architectural, electrical, systems, signaling, track, traction power, and other project disciplines.
• Review designs and technical work prepared by other designers and engineers for quality, completeness, constructability, and compliance with project requirements.
• Develop and review construction cost estimates for communications systems, equipment, materials, and installation.
• Participate in client meetings, technical workshops, design reviews, site investigations, and construction support activities.
• Provide technical guidance to less-experienced designers and engineers and contribute to the development of team standards, processes, and design practices.
• Support field investigations, construction administration, shop drawing reviews, RFIs, testing, commissioning, and troubleshooting as required.
• Help identify technical risks and develop practical, cost-effective solutions that meet client, operational, and regulatory requirements.
• Maintain a high standard of technical quality across all assigned deliverables and project phases.

Requirements

• Bachelor’s degree in Electrical Engineering, Systems Engineering, Telecommunications, or a related discipline.
• 10+ years of relevant experience in communications systems, electrical systems, rail/transit systems, telecommunications, or a closely related field.
• Demonstrated experience designing and delivering communications systems for rail, transit, transportation, aviation, or other complex infrastructure environments.
• Strong understanding of communications networks, including fiber optic infrastructure, Ethernet, routers, switches, wireless communications, network architecture, and related technologies.
• Experience developing detailed engineering/design documentation, including contract drawings, specifications, equipment schedules, network diagrams, and system architecture documentation.
• Experience with AutoCAD, MicroStation, or similar design platforms; familiarity with BIM/Revit environments is an asset.
• Ability to interpret and apply technical standards, specifications, codes, and client design criteria.
• Experience coordinating multidisciplinary designs and working directly with project managers, engineers, architects, contractors, vendors, and clients.
• Strong understanding of the full project lifecycle, from conceptual design through construction and commissioning.
• Ability to independently manage technical assignments, prioritize competing deadlines, and take ownership of deliverables.
• Professional Engineer (PE) license preferred, or demonstrated progression toward professional registration.
• Strong written and verbal communication skills, with the ability to explain complex technical concepts clearly to both technical and non-technical stakeholders.
• Experience providing technical direction, mentoring, or quality review of junior staff is preferred.
