Who We Are At Proxima Fusion, we're driven by a bold mission – to redefine the future of sustainable energy. Our unique concept, built upon the groundbreaking W7-X stellarator and the latest advances in technology, paves the way for commercially viable fusion power plants.
What’s more, our work in stellarator optimization, powered by cutting-edge computation and machine learning, is propelling us into uncharted territories of fusion technology. New higher performance design points are unlocked by high temperature superconducting magnets.
To fully grasp this huge opportunity, we’re building a team of extremely dedicated and passionate people who come together driving something extraordinary, radically transforming technology in the world.
WHY JOIN PROXIMA FUSION
YOUR IMPACT You will contribute to the design of Proxima Fusion’s Stellarator Model Coil (SMC), including the mechanical design of key systems, components and assemblies comprising both the SMC, as well as the equipment and tooling required to manufacture it. You will participate in the development of prototyping & testing plans, potentially participate in the physical testing of new designs, concepts and materials and develop the mechanical designs for novel tooling, equipment, and manufacturing processes.
As a mechanical design engineer, you will have a key role in the design, delivery and implementation of mechanical equipment, to enable ongoing research & development, as well as the manufacturing scale-up of the magnet components, systems, and associated tooling and equipment. You will also work with external collaborators and suppliers to develop designs, equipment, systems and materials

What We Are Looking For
INTERVIEW PROCESS
At Proxima Fusion, our mission is bold: making limitless clean energy a reality. To get there, we need a high-performing, diverse team that brings different perspectives, challenges assumptions, and builds together with purpose. We know that diversity of thought and experience leads to better ideas, stronger execution, and a more resilient team. We don’t look at how you identify, what you look like, who you choose to worship or what ethnicity you are. We care about what you can bring to the table.
