Come and join us in building the infrastructure our planet needs to achieve a sustainable future.We have successfully delivered large infrastructure projects across Canada since 2001. Our leadership and expertise span the entire value chain from research and development through construction, operation and maintenance of projects. Currently involved in some of Canada’s largest infrastructure projects, ACCIONA delivers solutions that contribute to the economic and social progress of the communities in which it operates. 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 new 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.
