Mechanical Design Engineer This is not a role where you will spend years designing the same components behind a desk. This is an opportunity to help engineer technology that could genuinely change how the world produces clean energy. You will join a pioneering climate-tech business developing cutting-edge carbon-negative systems that convert waste materials into valuable low-carbon fuels. The technology is already attracting significant investment and industry attention, and the next phase of growth is now underway. As a Mechanical Design Engineer, you will become part of a highly skilled engineering team working on the development of prototype, pilot, and future commercial-scale systems. If you enjoy solving real engineering problems, want to work on technology with purpose, and are excited by the idea of helping scale breakthrough clean-energy systems from concept through to reality, this role offers a genuinely rare opportunity. The responsibilities of the Mechanical Design Engineer include: * Developing mechanical designs for prototype, pilot, and commercial-scale process systems * Producing 3D CAD models, fabrication drawings, plant layouts, and engineering documentation * Supporting equipment integration, piping arrangements, structural layouts, and overall plant configuration * Collaborating closely with multidisciplinary engineering, controls, chemistry, and operations teams * Contributing to prototype build activities, te...
