• Is recognized as a Subject Matter Expert for CANDU Reactivity Control Units and maintains effective technical liaison with internal and external organizations.
• Provide technical leadership and mentoring of junior, intermediate and senior engineers, influencing and aligning engineering practice across projects.
• Develops new engineering concepts and design modifications to meet functional, regulatory, and lifecycle requirements.
• Devises and champions new approaches to complex or novel problems within the engineering specialty.
• Leads the resolution of critical and high‑risk engineering issues, providing timely, and defensible engineering solutions/direction.
• Addresses complex engineering challenges involving conflicting requirements, non‑standard materials, and difficult coordination constraints, establishing technically sound resolutions.
• Evaluates and confirms the feasibility, robustness, and technical soundness of proposed engineering methods and approaches.
• Apply extensive knowledge of engineering precedents and related disciplines to establish technical judgement and direction.
• Provides guidance on applicable codes, standards, and regulatory requirements related to the discipline.
• Performs critical reviews of design documents, calculations, drawings, and analysis reports, resolving complex or precedent‑setting technical issues.
• Review engineering assessments for the design and integrity of nuclear pressure boundary components.
• Review design documentation to ensure client requirements are met and initiate any corrective actions as necessary.
• Support technical and commercial interfaces with the client.
• To define work scope, plan activities, and coordinate engineering work for all design phases within major projects or across projects of considerable scope and complexity.
• Supports and guides the execution of technical engineering work packages to deliver within approved scope, budget, and schedule.
• Is responsible for reporting technical progress, risks and schedule status to technical and project management.
• Contributes to engineering budgets and provides technical input for defined work packages.
• Participates in development, interpretation, and advancement of engineering standards and contributes to technical forums within the area of specialty.
• Contributes technical input to operational and strategic planning processes, influencing engineering direction and resource deployment.
• Participate in the training and development of engineering staff.
• Operates with minimal technical supervision, receiving guidance primarily on overall objectives, and critical issues.

• A Bachelor'S or Graduate degree in Mechanical Engineering (or related discipline such as Materials or Nuclear Engineering) from a university of recognized standing.
• Licensed as a Professional Engineer in the Province of Ontario.
• Minimum 15 years of related work experience with CANDU reactor design and/or ASME pressure vessel design.
• Experience in classical stress calculation. Knowledge of first principles related to solid mechanics such as relationship between stress and strain, material properties, fatigue, fracture mechanics, creep.
• Experienced in producing drawings (including dimensioning and tolerancing). Knowledge of…
