Focused Energy is a fusion energy startup with the goal of generating unlimited clean energy to responsibly meet future global demand. With the use and commercialization of laser-induced inertial fusion, a clean and highly efficient power generation technology is coming within reach, suitable to ensure a secure and scalable future energy supply. We are seeking a highly skilled and motivated Computational Fluid Dynamics (CFD) Engineer to join our Science and Engineering team. This is a critical, hands-on technical role responsible for developing and integrating advanced CFD models of the fusion chamber environment. Your work will directly inform the design of the core reactor systems, ensuring component survivability and optimizing the key processes within the chamber. You will be responsible for translating complex gas dynamics—from free-molecular to continuous flow regimes—into reliable computational predictions that are coupled into our multi-physics design framework.
