Job description
You will be responsible for mechanical calculation work for a system or part of the system related in Thorizon’s reactor design. You will be a key person of the calculation expertise center, whose primary missions are, on the one hand, to provide expertise in this area to the system in charge of the reactor design studies and, on the other hand, to define, execute, and deliver the mechanical deliverables with calculation specification, calculation strategy and hypothesis and calculations notes within the performance, cost, and time constraints of our project.
Within this general framework, you will own your activities to ensure the quality and validity of the studies and work performed and develop mechanical calculation expertise in line with the needs of the Thorizon project and its future developments. Concretely, you support system design teams (from PILOT to FOAK/NOAK) by providing deep calculation engineering input and ensuring that all design choices are technically sound and consistent with requirements and applicable Codes & Standards.
You take responsibility for the correct use of calculation tools and for maintaining high-quality, reliable studies. A key part of your role is to ensure strong interfaces between mechanical engineering and the wider organization: system design, project teams, licensing, safety, functional leads, and management. Your level of expertise allows you to prioritize based on the importance of the needs, and as an expert, you have the power to recommend any necessary actions for the project related to your area of expertise.
Furthermore, you participate in external networks, including international initiatives, to stay at the forefront of industry development.
