• Coordinate with project managers, discipline engineers, and other stakeholders to ensure safe and efficient execution of piping replacement projects.
• Provide technical oversight during fabrication and installation phases, including inspection, testing, and documentation review.
• Ensure all work is compliant with relevant codes and standards such as ASME B31.1, CSA N285.0, and/or ASME B31.3.
• Participate in design reviews, hazard assessments, and quality assurance activities.
• Support client interfacing and reporting, contributing to a highly collaborative team environment.

Qualifications & Experience:

Must-Have:

• Bachelor’s degree in Mechanical Engineering with a valid P.Eng. license in Ontario.
• Minimum 7 years of experience in mechanical and piping engineering, preferably within regulated industries.
• Strong knowledge of piping codes including ASME B31.1 , CSA N285.0 (nuclear), and ASME B31.3 (oil & gas).
• Experience with piping system evaluations, replacements, and upgrades in aging infrastructure.
• Excellent communication skills and ability to work in a cross-functional engineering team.

Nice to Have:

• Previous experience working in a nuclear facility or with nuclear utilities.
• Familiarity with nuclear safety and quality assurance protocols.

Work Environment:

This role is primarily onsite at a nuclear facility and will involve working in an operational plant environment with strict safety and regulatory protocols.

Note: Due to the nature of the work, eligibility for security clearance is required.
