Mechanical Engineer
Your mission
You will be responsible for mechanically design a system or part of the system related in Thorizon’s reactor design. You will be a key person of the mechanical 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 studies with drawings, part lists, specifications for manufacturing and supplying 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 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 mechanical 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 design tools and for maintaining high-quality, reliable engineering studies.
In This Role You Will
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.
In this environment, you get the unique opportunity to put your knowledge to the best use, develop your ideas, explore various aspects of mechanical engineering, and play a crucial role in the company’s growth.
About You
Thorizon is a European deep tech scale up developing a new generation of small modular molten salt reactors to power the AI and industrial age with abundant, clean and affordable energy. With offices in Amsterdam, Eindhoven and Lyon, we are developing a reactor that combines inherent safety, high temperature industrial heat and competitive electricity generation. Designed to recycle long lived nuclear waste as fuel, our technology also advances a more circular nuclear fuel cycle.
Having completed the conceptual design of our demonstrator reactor and secured the site for its deployment in Noord Holland, we are entering the next phase: detailed engineering, licensing, supply chain development and construction of our first of a kind reactor, paving the way for commercial deployment in Zeeland.
We work alongside leading industrial partners including Orano, VDL Groep, Tractebel and EPZ. Our program has been selected by the European Commission and by the French government under the France 2030 investment plan, and is recognized by the Dutch government as a flagship innovation project strengthening the country's long term competitiveness.
At Thorizon, we believe a strongly coupled multidisciplinary technology development requires a culture of full openness and transparency. That’s why we foster values like unity, communication, and support to ensure we grow together as a team while achieving our purpose.
