Mississauga, Ontario, Canada

This position requires an experienced individual who is self‑motivated and capable of working independently with minimal supervision, plans and executes the engineering activities assigned by the Technical Lead and/or Technical Manager, resolves routine and complex technical issues, and seeks guidance primarily for "first‑of‑a-kind", high‑risk, interdisciplinary or very complex matters. The candidate shall be able to independently deliver most of the assigned work, while knowing when to seek specialized help from subject matter expert.

The qualified individual will be responsible for, but not limited to, the following:

• Perform pipe stress evaluation of piping systems (nuclear class or non‑nuclear class) in accordance with ASME Section III, Div.1, and/or ASME B31.1/B31.3 code requirements, including thermal, fatigue, seismic, linear and non‑linear analyses.
• Prepare engineering computations and analyses using applicable software (e.g., PipeStress, AutoPipe, Cesar II, MathCAD, ANSYS and LS‑DYNA, etc.).
• Model complex piping and support arrangements using finite element techniques.
• Review of technical documents and drawings (e.g. equipment General Arrangement drawings, nozzle loads, equipment layout drawings, isometrics, pipe supports, flow diagrams and P&ID), calculations, design/analysis reports, design requirements, bill of materials, design specifications, technical specifications, data sheets, etc.
• Review 3D piping model and equipment layout.
• Prepare technical documents, such as calculations, design/analysis reports, design requirements, piping stress design basis reports, piping design specifications, technical specifications, data sheets, etc.
• Support preparing TSSA CRN registration packages for pressure boundary systems.
• Function as technical interface with client, suppliers, inter‑discipline engineering teams, construction partners and project management groups.
• Perform site visits to client and supplier shops as required. Support field construction and execution activities, as needed (site visits are required).
• Perform engineering work following AtkinsRéalis/Candu Energy QA programs, and applicable codes, standards, and regulation requirements.
