Mechanical Design Engineer, Bristol

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, technical problem solving, and continuous improvement initiatives

Requirements:

• Degree qualified in Mechanical Engineering or a related discipline
• Experience using 3D CAD software within an engineering or manufacturing environment, ideally SolidWorks
• Strong problem-solving ability with a practical engineering mindset and the confidence to work across both hands-on and design-based engineering activities
• Experience within process plant, energy, industrial manufacturing, chemical, waste processing, or similar engineering environments would be highly advantageous
• Exposure to pressure systems, piping layouts, skids, integrated plant equipment, prototype development, fabrication, FEA, or CFD would be beneficial, alongside the ability to thrive in a fast-paced multidisciplinary engineering environment

What this is offering: 

• Salary of £35,000-£50,000 depending on experience. 
• Flexible working hours. 
• Private healthcare and life assurance
• Share options and long-term growth potential
• 25 days holiday plus bank holidays + Additional birthday leave

This is an excellent opportunity for an engineer who wants to do more than simply “support projects”. 

You will help shape the future of a breakthrough technology at a critical stage of commercial growth, while building experience that could define the next stage of your engineering career.
