Mechanical Engineer (Process Systems)

We are now looking for an Advanced Research Engineer to join our Engineering Design Group, focusing on hydrogen and alternative energy systems. This is an exciting, hands-on engineering opportunity to play a key role in the development and delivery of next-generation energy systems. Working across the full project lifecycle, from feasibility and concept development through FEED and detailed design to commissioning and delivery, you will contribute to innovative projects that are helping shape the future of sustainable energy. We are seeking a Mechanical Engineer with a strong process engineering bias and proven experience in complex industrial systems. You will be involved in the design and integration of technologies including hydrogen production plants, pressurised pipework systems, and alternative fuel solutions such as ammonia and methanol. The role requires practical experience of FEED engineering, preparation and review of PFDs and P&IDs, equipment specifications, and system integration, together with a sound understanding of process safety and risk assessments, including HAZOP, ATEX, and DSEAR. Working within a multidisciplinary engineering team, you will undertake technical analysis, develop engineering solutions, and support project delivery from concept through to implementation. You will collaborate closely with customers, suppliers, and internal stakeholders to ensure designs are safe, efficient, and fit for purpose, helping to bring cutting-edge technologies into real-world operation and accelerate the transition to a low-carbon future.
