Nuclear Thermal-Hydraulics Engineer – CSMC CSMC is shaping the future of advanced energy and aerospace technologies through innovation in nuclear microreactors, quantum sensing, and deep‑tech engineering. We’re looking for a Nuclear Thermal‑Hydraulics Engineer to join our growing team and help us develop micro‑modular reactors for space and other extreme environments. About the Role We are seeking a Nuclear Engineer specializing in thermal‑hydraulics to support the design and analysis of advanced reactor systems. The successful candidate will develop, implement, and validate models to assess heat transfer, fluid flow, and system performance under steady‑state and transient conditions. Key Responsibilities Perform thermal‑hydraulic and system‑level analyses for reactor designs. Develop models using codes such as RELAP5, TRACE, OpenFOAM, COMSOL, or ANSYS Fluent. Analyze heat transfer, flow distribution, and two‑phase flow phenomena. Support safety and performance assessments through coupled neutronic‑thermal simulations. Evaluate coolant system design and decay heat removal capabilities. Prepare technical reports and present analysis results to project teams and stakeholders. Support the business development activities of the company including proposals, RFPs, regulatory applications, and other as needed. Qualifications Bachelor’s, Master’s, or Ph.D. in Nuclear Engineering, Mechanical Engineering, or related discipline. 2+ years of relevant experience in thermal‑hydraulics analysis (industry, research, or graduate work). Demonstrated proficiency in one or more of the following: RELAP5, TRACE, OpenFOAM, ANSYS Fluent, COMSOL, or equivalent CFD/system codes. Strong understanding of heat transfer, single‑ and two‑phase flow, and reactor cooling systems. Experience with Python, MATLAB, or similar scripting tools for post‑processing and data automation. Excellent analytical and communication skills, including strong writing skills. Experience with CFD coupling, or multi‑physics simulation. Exposure to experimental validation or test loop design. Prior experience with Aerospace or Military Grade engineering is a plus. Why Join CSMC The chance to help shape the future of energy, space, and defence in Canada. Exposure to cutting‑edge technologies, with mentorship from experienced founders and executives. A collaborative, mission‑driven culture with a flat hierarchy and room for rapid growth. Equity participation in a high‑growth startup. The candidate must be a highly motivated self‑starter, capable of working through complex issues to solve problems that are not off the shelf. They should be capable of moving through setbacks and finding ways to persevere. Exceptional excel, powerpoint, and communication skills are essential. Must be eligible to work in Canada, and able to attain appropriate security clearances requisite with an aerospace & nuclear company of this type, and commensurate nuclear engineering position. Candidates will be subject to background checks. This is a second floor opportunity (on a space elevator). This is about an opportunity to learn, be given responsibility, and grow with the company. We have an affinity for diverse people and thinkers with unique perspectives and life experience. CSMC is an equal opportunity employer supporting diversity and inclusion.
