Position Overview

The Director/VP of Nuclear Engineering is a senior technical leader responsible for CSMC's nuclear engineering strategy, reactor design activities, and engineering governance. This role provides leadership across reactor physics, thermal-hydraulics, systems engineering, safety analysis, and regulatory readiness, while supporting early CNSC engagement and licensing strategy.

You will work directly with the CEO, COO, Chief Scientist, and EVP Engineering Emeritus, playing a central role in advancing CSMC's microreactor technology from concept to prototype and deployment.

This is an on-site leadership role based in Waterloo, Ontario, 5 days a week.

Key Responsibilities

Nuclear Engineering Leadership

• Lead the Nuclear Engineering department, including reactor design, analysis, modelling, and systems integration.
• Establish engineering processes aligned with CSA N286, N299, and CNSC expectations for design control, configuration management, and technical baselining.
• Provide technical authority across reactor physics, thermal-hydraulics, multiphysics modelling, and safety-critical engineering decisions.

Reactor Design & Development

• Oversee development of microreactor systems, including core design, heat-transport systems, shielding, and safety-related components.
• Guide engineering teams in producing high-quality technical deliverables, design documentation, and analysis packages.
• Support prototyping, test planning, and experimental validation activities

Regulatory & Licensing Support

• Support early-stage regulatory engagement, including CNSC Vendor Design Review (VDR), pre-licensing discussions, and licensing strategy development.
• Ensure engineering outputs meet regulatory defensibility standards and align with licensing basis expectations.
• Collaborate with regulatory affairs, quality, and safety teams to prepare technical basis documents, safety analyses, and design submissions.

Program & Project Leadership

• Manage multidisciplinary engineering teams and external partners across multiple concurrent projects.
• Lead technical planning, resource allocation, risk management, and execution oversight.
• Support proposal development, customer engagement, and strategic partnerships with government, national labs, and industry.

Technical Communication & Stakeholder Engagement

• Produce high-quality technical reports, studies, and engineering assessments.
• Present engineering findings to executives, regulators, partners, and internal review boards.
• Represent CSMC in technical forums, industry groups, and strategic discussions.

Required Qualifications

• Master's degree (or higher) in Nuclear Engineering, Mechanical Engineering, or related field.
• 10-15+ years of experience in nuclear engineering, reactor development, or regulated nuclear programs.
• Demonstrated experience in CNSC-regulated environments, including VDR, PDR, or facility licensing.
• Strong understanding of nuclear systems, reactor physics, thermal-hydraulics, and multiphysics analysis.
• Hands-on experience with tools such as ANSYS, COMSOL, OpenFOAM, MCNP, SERPENT, or equivalent.
• Experience working within a nuclear management system and nuclear QA environment (CSA N286/N299).
• Proven leadership experience managing engineering teams or technical programs.
• Excellent written and verbal communication skills.
• Ability to thrive in a fast-paced, early-stage engineering environment.

Preferred Qualifications

• Experience with advanced reactors, microreactors, or FOAK nuclear technologies.
• Experience in defence, aerospace, or remote-operations energy systems.
• Background in robotics, automation, or mechatronics (asset).
• Experience with prototyping, experimental systems, or test loop development.
• Familiarity with nuclear economics, policy, and deployment strategy.
