AI Engineer

Summary

Join Transmutex to pioneer AI-driven innovations—develop LLM-powered web apps, optimize particle accelerators with ML & RL, and shape the future of nuclear energy with cutting-edge AI solutions.

About us

Transmutex is a Geneva-based start-up founded in 2019. We aim at reinventing nuclear energy by using an accelerator-driven system (ADS) 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.
