Job summary

WSP USA is seeking a Lead Professional, Signal Engineer-CBTC to lead technical review and oversight of CBTC and fixed-block signaling projects in New York and New Jersey offices. You will coordinate with NYCT operations, suppliers, and design teams to ensure safety and interoperability during the migration to CBTC.

The ideal candidate has 7+ years in signaling, deep knowledge of interlocking logic, and hands-on experience with both relay-based and software-driven systems.

Qualifications

• Bachelor’s degree in electrical, systems, or railway engineering.
• 7+ years in fixed-block and/or CBTC signaling design or maintenance.
• 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.

Responsibilities

• 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.
