• Prepare and review engineering calculations, system studies, technical specifications, and design change packages.
• Perform system assessments including load flow, short‑circuit, protection coordination, arc‑flash hazard analysis, harmonic analysis, surge protection and system reliability studies.
• Support equipment qualification, environmental/seismic assessments, and aging management programs.
• Interface with operations, maintenance, licensing, and safety teams to resolve complex technical issues.
• Ensure compliance with nuclear codes, standards, and regulatory requirements.
• Provide technical oversight of vendors, contractors, and junior engineers.
• Support commissioning, testing, troubleshooting, and plant start‑up activities.
• Contribute to risk assessments, failure investigations, and corrective action programs.
• Perform engineering work following AtkinsRéalis /Candu Energy procedures and QA programs, and applicable codes, standards, and regulatory requirements.
• Coordinate and interface with client(s), suppliers, stakeholders and other design disciplines to execute assigned engineering work.
• Become involved in conceptual, preliminary and/or detailed design phases to support CANDU and other Nuclear electrical systems and modifications.
• Provide input to technical documents, that include engineering drawings (including GAs, DDs, EDs), change paper markups, calculations, design/analysis reports, design requirements, design manuals, bill of materials, design specifications, technical specifications, component specification sheets, commissioning specifications, etc.
• Participate in review of interfacing discipline's documentation.
• Provide input to requisitions or Engineering Quotation Requests (EQR) for equipment and materials to support procurement.
• Interface and provide technical guidance and instruction to designers/drafters.
• Supervise, coordinate and review the work of junior and assistant engineers/designers, prepare estimates, monitor schedules and assigning work to team members to meet completion dates.
• Prepare scope of work and provide input to bid proposals.
• Perform field walk-downs during different design phases and prepare Walkdown reports as required.
• Assist with field construction and execution activities, such as: field changes, design revisions, commissioning, AFS, closeout, etc.
• Complete the assigned scopes or tasks within given budget and schedule, and in good quality.
• Provide prompt response and engineering resolutions on any critical engineering related matters.
