Lead Professional, Signal Engineer - CBTC

Lead Professional, Signal Engineer-CBTC

WSP is currently initiating a search for a Lead Professional, Signal Engineer-CBTC to join our Transit and Rail/Systems Engineering in one of our New York or New Jersey offices. This position can be based out of New York City, Valhalla-NY, Troy-NY, Lawrenceville-NJ, Morristown-NJ or Newark-NJ.

The Signal Engineer provides specialized technical support and oversight of both fixed-block signaling and application to the CBTC system program. This position ensures that signal designs, interlocking logic, and mixed-mode block configurations are reviewed, validated, and approved in compliance with NYCT operational principles and safety standards. The ideal candidate possesses a deep understanding of both traditional relay-based signaling and software-based interlocking logic, with hands-on experience to support NYCT projects.

This role serves as a vital liaison between the supplier, designer, and NYCT Operations to facilitate design acceptance, support test readiness, and ensure system safety and operational continuity throughout the migration to CBTC.

• Provide technical review and approval of block design drawings and documentation for mixed-mode (CBTC and fixed-block) operation.
• Serve as a liaison between the CBTC supplier, designer, and operations for all matters related to signal design coordination and block approval.
• Review and assess the implementation of interlocking logic in both the relay-based fixed-block design and the CBTC subsystem software, ensuring operational and safety compliance.
• Review and approve test procedures related to interlocking logic, signal aspects, and control sequences to confirm compliance with Authority and NYCT requirements.
• Evaluate software state machine logic used to implement interlocking functions in CBTC subsystems and ensure proper alignment with NYCT signaling principles and operational rules.
• Provide assurance that signal design changes maintain interoperability, safety integrity, and system maintainability during migration from fixed-block to CBTC control.
• Support interface alignment between CBTC zone controller logic, relay interlockings, and field signal equipment.
• Participate in design and field review meetings with NYCT Engineering, Operations Planning, and maintenance teams to address design, testing, and configuration issues.
• Track and report on signal design deliverables, test progress, and open design comments requiring review or resolution.
• Perform additional responsibilities as required to support the successful integration, validation, and acceptance of the CBTC and fixed-block signaling systems.
• Exercise responsible and ethical decision-making regarding company funds, resources and conduct, and adhere to WSP's Code of Conduct and related policies and procedures.
• Perform additional responsibilities as required by business needs.

• Bachelor's degree in electrical, systems, or railway engineering;
• 7+ years of progressive experience in fixed-block and/or CBTC signaling system maintenance and/or design may be considered in lieu of a degree.
• Proven record of reviewing, approving, and coordinating block design packages for mixed-mode signaling operation.
• Experience developing or reviewing interlocking logic test procedures and software state machine implementations.
• Understanding of NYCT signal principles, operational practices, and legacy control systems.
• Understanding of vital and non-vital signal logic, relay-based control circuits, and their translation into CBTC subsystem software.
• Familiarity with Interface Interoperability Specification signal design standards.
• Working knowledge of interlocking design, block layouts, overlap logic, and control line functions.
• Understanding of test sequencing, verification, and validation of signaling systems within mixed-mode operation.
• Prior involvement in at least one major Train Control System deployment or migration project within NYCT or a comparable transit agency.
• Ability to work during off-hour testing or commissioning as needed.
• Ability to support field reviews, test witnessing, and agency coordination meetings.
• Flexibility to perform additional responsibilities as assigned to ensure program success.

Preferred Qualifications

• Exceptional analytical and diagnostic skills for reviewing detailed circuit and software logic.
• Effective communicator able to represent technical findings and recommendations to NYCT operations and design teams.
