ACCIONA is a global leader in sustainable infrastructure and renewable energy, delivering innovative, forward-thinking solutions in over 40 countries. We're proud to be shaping some of the most complex and transformative infrastructure projects in North America.

In partnership with Metrolinx, ACCIONA is playing a key role in the design and construction of the Eglinton Crosstown West Extension (ECWE), a 9.2-kilometre westward addition to Toronto’s Line 5 light rail transit network. This major infrastructure project includes seven new stations and installation of rail and systems under a progressive design-build model.

The S&TCS; Design Manager is responsible for the technical delivery, systems integration,



and engineering governance of all signaling and train control infrastructure across the ECWE corridor.

This role serves as the lead technical authority managing the design interface between the Primary Lead Designer, the signaling equipment manufacturer and transit authorities. The primary focus is ensuring that the engineering design is fully constructible, safe, compliant with project specifications, and seamlessly integrates Alstom's proprietary CITYFLO 650 CBTC platform into both the current extension and the existing Line 5 backbone.

Beyond its technical scope, the ECWE project represents a significant investment in sustainable urban mobility, expected to reduce greenhouse gas emissions by up to 5,800 tonnes annually and eliminate over 6.5 million vehicle trips each year when combined with the full Line 5.

This is a unique opportunity to join a dynamic, multidisciplinary team on a complex, high-value project that supports long-term regional growth and environmental sustainability.

Technical Interface & Systems Integration

OEM Design Integration : Act as the primary technical conduit with Alstom to oversee the application engineering and architecture of their CITYFLO 650 CBTC system.

Technical Submittal Review : Lead the engineering review, verification, and technical sign-off of Alstom's design data, trackside layouts, application logic, and software drop releases.





Interface Control Management : Author, update, and manage Interface Control Documents (ICDs) governing physical and digital boundaries between Alstom equipment, wayside systems, and the central control facility.

Brownfield Connectivity : Direct the technical design coordination required to integrate new ECWE data loops with the existing active Line 5 signaling infrastructure at the Mount Dennis hub.

Engineering Governance & Constructability

Design Optimization : Review engineering submissions from the Lead Designer to enforce constructability, identify design gaps, and eliminate spatial or logic clashes before construction release.

Digital Engineering (BIM) : Utilize BIM/Navisworks software to perform multi-disciplinary coordination, resolving physical clashes between signaling cables, trackway assets, structural elements, and MEP systems.

Stakeholder Technical Approvals : Manage the technical review cycle with Infrastructure Ontario, Metrolinx, and the TTC to resolve engineering comments, clear variances, and secure Stage Gate approvals.

Technical Change Management : Evaluate and provide technical impact assessments for any proposed design changes, modifications, or field variances affecting the S&TCS; network.

Functional Safety & Testing Governance

RAMS Case Coordination : Collaborate with Alstom's RAMS engineers to ensure the system architecture complies with CENELEC EN 50126/8/9 safety lifecycles and achieves required Safety Integrity Levels (SIL).

Testing Methodology Design : Oversee the technical design of testing protocols for Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) to ensure testability in the
