Renaissance Fusion is a startup aiming to develop and commercialize a nuclear fusion reactor with net electricity production by the 2030s. To achieve this, we rely on a unique combination: a proven reactor, the "stellarator," designed and assembled in modules, integrating a system of superconducting magnets and liquid metal walls. The technologies developed could also be used for other applications in the shorter term. Our team is made up of world experts in the fields of nuclear fusion, engineering, and the energy sector. We are based near Grenoble, a city renowned for its high-tech research ecosystem. We are looking for an Analytical Chemist – Process and Materials to ensure the safe, compliant, and efficient management of all chemical materials used and generated in R&amp;D and pilot-scale processes. The role focuses on analytical characterization of incoming and outgoing chemical streams, chemical inventory and management, and the definition of safe frameworks for executing experimental tests involving chemistry, for the development of our processes and their characterization.

Renaissance Fusion is the first Magnetic Confinement Fusion company in the EU. We are building the first net-energy producing stellarator by combining proprietary innovations in modular design, the manufacturing of next-generation High-Temperature Superconducting (HTS) magnets, and liquid-metal (LM) walls. We are forming a team of the brightest, most driven scientists and engineers to realize and commercialize our non-fusion products within 2 years and integrated fusion solutions within 10 years.
