  • Participate in risk assessments, design reviews, and constructability evaluations. 

  • Ensure strict adherence to CSA N299, CSA N285 and ASME Section III codes and standards where applicable.

What you will bring:

Technical and Industry Experience: 

  • Extensive experience working on Bruce Power and/or OPG projects, with deep knowledge of nuclear industry regulations and best practices. 

  • Expertise in mechanical equipment such as pumps, compressors, pressure vessels, storage tanks, heat exchangers, HVAC systems, fire protection systems, and piping systems

  • Strong proficiency in engineering software for design, modeling, and analysis. 

  • Advanced understanding of nuclear safety principles, quality assurance, and regulatory compliance. 

  • Ability to lead complex engineering projects and provide innovative solutions to technical challenges. 

  • Experience in stakeholder engagement, project management, and regulatory interactions

  • Strong ability to interpret and apply CSA N299, CSA N285 and ASME Section III codes and standards in mechanical engineering tasks.
