Mechanical Engineer (Pressure Boundary & Analysis)

Job Title: Mechanical Engineer (Pressure Boundary & Analysis)

Location: Peterborough, ON (Hybrid)
    
Estimated Duration: 12 Months

Position Overview

This engineering role reports to the manager responsible for mechanical systems integrity and analytical assessments. The individual in this role sets technical strategy for projects and serves as a primary technical liaison for both in-house and external stakeholders.

The mechanical engineering team specializes in systems that maintain structural integrity under pressure, particularly those tied to CANDU reactor operations. Work involves developing, validating, and supporting pressure-boundary equipment and components used in automated fueling systems, isotope production units, robotics, and service tools used in nuclear settings.

Key Responsibilities

• Carry out the design, testing, and commissioning of intricate mechanical assemblies across their entire operational lifecycle.

• Generate or validate technical records including drawings, bills of materials, design documents, and equipment specs.

• Conduct initial 3D modelling for concepts and apply stress analysis methods.

• Employ design approaches that ease production and assembly.

• Provide engineering insight to internal teams such as drafting, sourcing, production, testing, QA, and commissioning.

• Engage in design sessions and technical discussions, including external reviews.

• Use both traditional and simulation-based techniques (like FEA) to evaluate structural stresses in hardware such as piping, support structures, and vessels.

• Stay informed on regulations and design standards relevant to the nuclear sector in Canada.

• Contribute to high-quality outcomes by managing design work effectively, tracking progress, and maintaining strong performance against objectives.

• Promote adherence to established internal processes, codes, and industry guidelines.

• Contribute to process improvements and adoption of new technologies.

• Participate in customer engagement and ensure that engineering work aligns with market expectations.

• May assist in proposal efforts including estimating, scope definition, and technical presentations.

• Identify and manage technical risks; communicate challenges and resolutions to leadership.

• Uphold safety and compliance standards throughout all project phases.

Qualifications

• Degree in mechanical engineering from a recognized institution.

• Actively pursuing licensure with the provincial engineering regulatory body.

• Up to three years of experience in highly regulated industries such as nuclear, aerospace, mining, or oil & gas.

• Exposure to project execution across full life cycles with some independent capability.

• Understanding of systems engineering principles and how various disciplines (controls, software, manufacturing) interact.

• Strong communication skills—able to convey technical topics to varied audiences.

• Analytical thinker with creativity and an aptitude for collaborative work.

• Open to occasional travel and short-term field assignments.

• Above all, an inventive and solutions-oriented mindset is essential.

Preferred Experience

• Hands-on familiarity with CAD tools (such as Inventor or SolidWorks) and simulation software (ANSYS, Caesar II, AutoPIPE, etc.).

• Background in CANDU-related work or experience in the Canadian nuclear industry.

• Working knowledge of CSA and ASME standards relevant to pressurized systems.
