Sr. Interface Coordinator

Who We Are

The ONxpress Civils Contractor General Partnership, a partnership between FCC Canada Limited and Aecon Infrastructure Management Inc., is a multidisciplinary Civils Joint Venture (CJV) team with global expertise in delivering innovative solutions for both railway and civil construction projects. Working under Alliance agreements with Metrolinx, the team is helping to modernize railway construction across the GO Transit network.

An Alliance framework, which is relatively new in Canada, is a collaborative partnership between the owner and contractor, who work together with a best-for-project mindset. By streamlining decision making, the Alliance helps ensure that high-quality work is delivered, certified, and transferred in a progressive, transparent, and risk-managed manner.

The Alliance operates with a core focus on safety, efficiency, and sustainability, while fostering strong relationships with stakeholders and rights-holders and contributing positively to local communities as a good neighbour. Through this collaborative approach, the Alliance is helping drive the modernization of key sections of the rail network as part of the GO Expansion Program.

If you're passionate about making a difference and want to be part of a progressive and modern way of working, we want to hear from you.

What You'll Do:

As a Senior Coordinator, you will play a key role in coordinating multidisciplinary design activities and managing technical interfaces across civil, structural, and railway systems disciplines, ensuring effective integration between design, construction, and project requirements.

• Lead multidisciplinary design coordination and interface reviews across Civil, Structural, Systems, and Construction teams to identify and resolve technical issues and design conflicts.
• Coordinate the development, review, and maintenance of Interface Control Documents (ICDs), interface registers, and related deliverables, ensuring interfaces are identified, tracked, and closed.
• Work closely with Design, Construction, Systems, and Digital Delivery teams to address interface requirements, constructability concerns, and construction sequencing.
• Lead design and interface coordination meetings, follow up on outstanding actions, and escalate unresolved issues that may affect project scope, schedule, or delivery.
• Monitor design deliverables and interface dependencies across project packages, coordinating with relevant teams to address gaps and potential impacts on design and construction schedules.
• Support and provide leadership to the Interface Manager in overseeing daily interface coordination activities.
• Lead the railway interface document reviews and working closely with Construction, Systema and Transversal Engineering, and Digital Delivery teams.
• Manage and prioritize submittals, RFIs, design documents, and coordination deliverables to ensure timely review and approval.
• Close follow up for interface related coordination, review of stakeholders, and escalate issues that may affect project success.
• Identify opportunities for early works based on third-party interfaces and collaborate with the Design Manager and Construction teams to develop implementation plans.
• Champion integration with the Integrated Digital Delivery team to enhance design management, estimating, and construction planning processes.
• Foster a highly collaborative environment between design and construction teams to efficiently resolve technical issues. • Conduct detailed constructability and interface reviews across multidisciplinary design packages to ensure alignment with project requirements and enabling works.
• Monitor project progress by tracking deliverables, managing schedules, and providing status updates and recommendations to management.
• Mentor and support junior design coordinators, promoting continuous learning and best practices in design management.
• Liaise with delivery partners, consultants, and contractors to ensure seamless coordination and high-quality project delivery.

What You’ll Bring:

• Demonstrated experience in multidisciplinary design coordination and technical reviews on major infrastructure projects, preferably within rail or transit.
• Practical experience in interface management, including Interface Control Documents (ICDs), interface registers, stakeholder coordination, and resolution of technical interfaces between design and construction disciplines.
• Strong understanding of design development, construction sequencing, and technical interfaces between civil works and railway systems, with the ability to identify coordination gaps and propose practical solutions.
• Experience coordinating technical interfaces with external stakeholders, including contractors, consultants, utility owners, and third-party agencies, on complex infrastructure projects.
• Bachelor’s degree in engineering, architecture, or a related technical discipline.
• Minimum 5 years of relevant engineering experience on major infrastructure projects, including at least 2 years in multidisciplinary design coordination, technical interface management, or related project engineering roles. Experience in rail or transit projects is preferred.
• Proven expertise in civil and structural works; experience in transportation sectors (rail & transit, aviation, ports) is a strong asset.
• Demonstrated leadership in managing multidisciplinary coordination processes and constructability reviews.
• Experience in Interface management processes, stakeholder coordination and technical review of multidisciplinary engineering documentation.
• Strong organization, communication, and stakeholder management skills.
• Ability to manage multiple priorities in a fast-paced, large-scale project environment.
• Licensed Professional Engineer (P.Eng.) or eligibility for licensure is an asset.
