Job description

About Canadian Strategic Missions Corp. (CSMC)

Canadian Strategic Missions Corporation is building the capabilities that will shape Canada's future in space, defence, and energy. We focus on developing dual use systems that address critical challenges here on Earth while enabling sustained human activity beyond it. 

In a short time, CSMC has established real momentum. WE have secured significant government investment to advance next generation micro nuclear reactors in partnership with leading institutions, alongside expanding a portfolio of technologies designed for remote environments, national defence, and future space missions. These efforts reflect a broader ambition to deliver reliable power and critical infrastructure where it matters most.  
Our work is grounded in close collaboration with government and guided by a clear sense of purpose: to build sovereign capability at a time when it has never been more important. We care deeply about execution, long term impact and earning the trust required to deliver systems that will service Canada and its allies for decades.  

CSMC is a company for builders. We are a group of people drawn to hard problems, meaningful impact and the opportunity to shape systems that matter at a national and global scale. We are building a team that thrives in ambiguity, values execution, and is motivated by mission and impact. 

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, thermalhydraulics, 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 onsite 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, thermalhydraulics, multiphysics modelling, and safetycritical engineering decisions.

Reactor Design & Development

  • Oversee development of microreactor systems, including core design, heattransport systems, shielding, and safetyrelated components.
  • Guide engineering teams in producing highquality technical deliverables, design documentation, and analysis packages.
  • Support prototyping, test planning, and experimental validation activities

Regulatory & Licensing Support

  • Support earlystage regulatory engagement, including CNSC Vendor Design Review (VDR), prelicensing 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 highquality 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 CNSCregulated environments, including VDR, PDR, or facility licensing.
  • Strong understanding of nuclear systems, reactor physics, thermalhydraulics, and multiphysics analysis.
  • Handson 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 fastpaced, earlystage engineering environment.
Preferred Qualifications
  • Experience with advanced reactors, microreactors, or FOAK nuclear technologies.
  • Experience in defence, aerospace, or remoteoperations energy systems.
  • Background in robotics, automation, or mechatronics (asset).
