Job description

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

We have an exciting and innovative new team focussed on new and groundbreaking projects, allowing a chance to influence future new build design decisions – and we want you to be part of it! For this role, you can be based in either our Pickering or Mississauga, ON, offices, within a hybrid working environment.

As a Mechanical Engineer within the Enabling Projects team, you will play a key role in developing the technologies, infrastructure, and strategic initiatives required to support the next generation of nuclear and clean energy projects. Working within the New Build FEED organization, you will provide technical know-how across multidisciplinary teams, helping transform innovative concepts into executable projects that will enable future large‑scale deployment opportunities.

This is a highly visible role that combines technical excellence, systems thinking, and project leadership. You will work on complex engineering challenges, engage directly with clients and stakeholders, and influence critical decisions during the earliest stages of project development. Success in this role will contribute directly to securing future business opportunities and advancing strategic growth initiatives for the company.

Your role

• Responsible for engineering activities across feasibility, conceptual design, FEED, detailed design, commissioning, and operational support phases.
• Provide design solutions for process plant systems and pressure equipment.
• Prepare and/or review design documents for plant equipment of a chemical plant e.g. equipment design, design calculations, assessments, technical specifications, drawings, BOMs and System Code Classification.
• Prepare and review engineering drawings, equipment specifications, model reviews, and system integration activities.
• Perform and review equipment sizing, equipment selection, and system performance evaluations.
• Coordinate multidisciplinary engineering teams to ensure integrated and technically robust design solutions.
• Drive technical decision‑making, design optimization, and value engineering activities throughout project development.
• Identify, evaluate, and manage technical, operational, and project risks.
• Support evaluation of system total lifecycle costs, considering development, operation, maintenance, and disposal costs, to evaluate design and operational concept alternatives.
• Ensure designs comply with applicable codes, standards, licensing requirements, and company quality requirements.
• Support regulatory, permitting, and stakeholder engagement activities.
• Interface with internal and external stake holders as required.

About You

• Degree from an accredited university in Systems Design, Industrial, Mechanical or Process Engineering, or other suitable cross‑cutting engineering program.
• Minimum of 4 years of engineering experience in design and integration of complex systems required, with at least 2 years' experience in a regulated industry. Note that the Enabling Projects this team undertakes are not necessarily nuclear in nature, but some experience with the nuclear industry is preferred.
• Licensed by a professional engineering organization recognized in Canada is required. A licensed Professional Engineer from a Canadian provincial Professional Engineering organization (e.g., PEO) is preferred.
• Working knowledge of pressure boundary licensing requirements, and interface with TSSA/ CNSC.
• Proven technical risk and project management skills to allow for the effective planning and tracking of engineering development activities.
• Experience designing complex systems and providing systems integration engineering support to early FEED, construction and commissioning of design/build projects is required. Experience with complex industrial facility full life cycle engineering (e.g., operations, plant modifications, or decommissioning) is considered an asset.
• Demonstrated ability to analyze complex systems from a blank canvas through to completion, identifying potential risks and effective solutions.
• Desire and demonstrated ability to innovate and improve engineering activities and deliverables using emerging technologies is an asset.
• Effective organizational skills, including demonstrated skill in time management and setting priorities, with proven ability to manage technical activities effectively under tight schedules and budget.
• Excellent interpersonal skills and the ability to work in a multidisciplinary team environment, as well as communicating and working effectively with external customer and regulator stakeholders.
• Adaptable to change and thrive in a dynamic, team-oriented environment.
• Must be eligible for Security Clearance through Public Works and Government Services Canada.
• Must be able to travel to client sites as required, according to specific project needs.
