About Us We are a fusion materials startup based in London. We are a small team working within a group focussed on delivering technologies to enable fusion energy. You will have real ownership from day one of problems, decisions, and outcomes - alongside meaningful equity. In return, we hope to see driven and rigorous work. Our colleagues keep a critical eye on all decisions, want to support one another and can adapt to working on new tasks as the need arises. We invite applications from a diverse range of backgrounds to give a range of perspectives as we race towards bringing innovative, complex engineering solutions to market. This environment is designed for people who want to do extraordinary work with the potential for extraordinary impact. Summary We are looking for a talented Mechanical Engineer to design and develop precision mechanical systems, with an emphasis on vacuum-compatible hardware and integrated mechatronic solutions. This role combines advanced CAD design, vacuum system engineering, and mechatronics integration for Materials Science and Engineering. Key Responsibilities ● Create detailed 3D CAD models, assemblies, and manufacturing drawings for mechanical components and systems using tools such as Fusion 360 ● Design and specify vacuum systems, including chambers, pumping lines, seals, flanges, valves, and ultra-high vacuum (UHV)-compatible components. ● Designing systems and procedure...
