Summary
Are you passionate about advancing the future of clean energy and pioneering nuclear-based technologies? We are seeking a highly motivated Nuclear Chemist to join our multidisciplinary team, where you will play a key role in research, development, and innovation at the intersection of nuclear chemistry, energy production, and radiochemistry.
About us
Transmutex is a Geneva-based start-up founded in 2019. We aim at reinventing nuclear energy by designing START to optimize the transmutation of long-lived nuclear waste. The innovative combination of particle accelerators and fuel, based on existing long-lived radioactive waste, will let us develop energy process that will be intrinsically safe, will reduce the stockpile of long-lived waste, is resistant to proliferation, and will be cost competitive.
Main responsibilities
· Conduct cutting-edge research and experiments in nuclear chemistry with applications in molten salt-based separation of transuranic isotopes.
· Analyse nuclear materials, evaluating their properties, potential applications, and environmental impact.
· Work on nuclear electrorefining and define and verify methods for separation of nuclear heavy metal isotopes for a future reprocessing plant.
· Develop and optimize nuclear- and radiochemistry-based technologies in collaboration with multidisciplinary teams for reprocessing.
· Ensure compliance with safety standards and radiation protection regulations while maintaining a safe working environment.
· Oversee the production and chemical separation of radionuclides, including automation and engineering implementation of radiochemical processes.
· Establish, develop, and maintain infrastructure for radionuclide production and laboratory operations.
· Manage and organize the radiochemical laboratory, ensuring reliability of equipment and support of infrastructure.
· Provide support for preclinical and clinical studies linked to radionuclide applications.
· Prepare technical reports, documentation, and presentations to communicate findings effectively to stakeholders.
· Stay abreast of the latest advancements in nuclear chemistry, radiochemistry, and related technologies.
Qualifications and professional achievements
· Ph.D. in Nuclear Chemistry, Radiochemistry, or related field (or equivalent academic/technical background).
