About the Job

We are seeking an experienced System/Mechanical Engineer with a strong background in the development and integration of complex systems for passenger and freight rail vehicles. This role is ideal for a technically hands-on, detail-oriented professional who thrives on cross-functional collaboration and system-level thinking.

What You’ll Be Doing

As a System/Mechanical Engineer, you will be responsible for defining, integrating, testing, and supporting key rolling stock systems such as HVAC, braking, pneumatic, mechanical interfaces, and communication systems. You’ll collaborate with a multidisciplinary team across all phases of the project lifecycle: from concept development to manufacturing support, in-service troubleshooting, and refurbishment.

This position requires strong coordination skills to ensure that all subsystems operate as an integrated whole and meet regulatory, operational, and client-specific requirements.

Key responsibilities

• Define system-level requirements, interfaces, and performance criteria for various mechanical and onboard systems (excluding detailed electrical design).
• Collaborate with project managers, engineers, and designers to ensure consistency and alignment between design outputs and system requirements.
• Work closely with internal electrical and mechanical engineering teams to manage cross-disciplinary interfaces.
• Analyze functional performance and safety risks, supporting FMEA and system-level hazard assessments.
• Develop and maintain interface control documents (ICDs), system block diagrams, and requirement traceability matrices.
• Review and validate supplier documentation and component data to ensure compatibility and compliance with technical specs.
• Contribute to testing, commissioning, troubleshooting, and validation of new or modified vehicles.
• Contribute to the development of verification and validation plans, test procedures, and technical reports required for certification.
• Coordinate with regulatory authorities, certifiers, and clients to ensure systems meet all applicable standards (APTA, AAR, EN, UIC, etc.).
• Stay up to date with evolving industry trends, technologies, and regulations impacting system integration and safety in rolling stock.

Required qualifications

• Bachelor’s degree Mechanical Engineering.
• Member of OIQ (Ordre des ingénieurs du Québec) or another provincially recognized engineering regulatory body in Canada.
• 5–10 years of experience in systems engineering within the rail, transportation, or related industries.
• Strong understanding of rolling stock systems integration and relevant industry standards (APTA, AAR, TC, EN series, …).
• Experience managing interfaces across mechanical and electrical systems.
• Familiarity with maintenance and lifecycle challenges associated with passenger and freight rolling stock.
• Proficiency with CAD tools and system-level architecture documentation.
• Strong communication, organizational, and problem-solving skills.
• Ability to work in a fast-paced, collaborative environment with multiple stakeholders.
• Bilingualism (French/English) is an asset for collaboration with clients and suppliers.
