Sr. Piping Engineer - Design

Overview

AtkinsRéalis is one of Canada’s largest private sector nuclear engineering groups. We provide a wide range of services to the nuclear industry in Canada and around the world for more than 60 years, and are proud to steward Canadian CANDU nuclear technology.

• Develop and conceptualize plans, details, and drawing sections to clearly communicate construction and fabrication requirements.
• Review scope documents, P&IDs, and supporting technical documentation (e.g., assessment reports, design requirements, design manuals, piping specifications, system and code classification lists) and prepare presentation materials summarizing design changes and impacts.
• Prepare and develop piping layouts and design deliverables, including general arrangement, isometric, and piping support drawings, in accordance with P&IDs, design inputs, applicable standards, and project specifications.
• Collaborate with drafters and designers to produce 2D drawings and 3D models for approved modifications and design changes.
• Provide design inputs to the piping stress team and coordinate reviews; address comments and support timely comment disposition.
• Plan, assign, and manage the distribution of drafting and 3D modelling tasks to support schedule and quality objectives.
• Identify cost‑effective, technically compliant solutions to design challenges.
• Perform checking and back‑checking of 3D models and piping drawings to verify accuracy, completeness, and compliance with project standards.
• Support the preparation of TSSA registration packages for pressure boundary modifications and coordinate technical interfaces with regulatory bodies.
• Ensure orderly coordination and document control by reviewing design inputs and outputs at all stages of the design process.
• Interface with customer engineering representatives (SNN) and project stakeholders to support design alignment and issue resolution.
• Provide management with timely updates on schedule, technical progress, risks, and deliverable status for assigned scopes.
• Provide timely engineering responses and technical resolutions to critical design and field issues.
• Attend site visits, walkdowns, and project meetings, as required.
• Ensure engineering deliverables are completed on time and in accordance with the applicable QA program, codes, standards, regulations, and procedures, with a strong focus on quality.
• Mentor and provide technical guidance to junior engineers, designers, and drafters.
• Maintain valid personal qualification records and complete required training within timelines.
• Participate in interdisciplinary model reviews (3D model reviews/clash detection) and coordinate piping interfaces with mechanical, civil/structural, electrical, I&C, and HVAC disciplines.
• Incorporate constructability, accessibility, maintainability, and ALARA considerations into piping routing and design, including field installation constraints.
• Develop and verify material take‑offs (MTOs) and support procurement through BOM reviews, technical queries, and vendor drawing reviews, as required.
• Provide field engineering support during installation, including responding to RFIs, reviewing field changes, and ensuring as‑built documentation is captured and issued.

• Degree in Mechanical Engineering from an accredited university with a minimum of 10+ years of experience (minimum 5‑8 years in the nuclear industry as Piping Engineer working on nuclear piping systems).
• Experience in working on EPC and/or EPCM projects.
• Registered Professional Engineer in the Province of Ontario and member in good standing.
• Strong knowledge of CSA N285, ASME B31.1, ASME B16.5, ASTM materials, ASME/ANSI PS‑15‑69 and ASME Sec III Div I requirements.
• Robust working knowledge of piping specifications, administrative and technical practices, design instructions, Flow Diagrams, P&IDs, and interpreting vendor information.
• Experience in the generation of Site / Plot Plans, Piping General Arrangement Drawings, Piping Plans/Layouts, Piping Isometrics, Sections/Details, Pipe Support Details, Piping Bills of Material.
• Ability to conceptualize design details independently with minimal supervision or instructions from Engineers.
