What are we looking for

We have an opportunity for a Manufacturing Process Engineer who will be a key member of the Production Engineering team responsible for supporting the industrialisation, optimisation and continuous improvement of Catalyst Coated Membrane manufacturing processes. The role focuses on enabling a stable, scalable and high-quality production process through hands‑on engineering support, structured problem solving and continuous improvement activities. A core aspect of the role is supporting the introduction of new equipment and processes into manufacturing. This includes contributing to equipment specification, supporting supplier engagement, assisting with commissioning activities and ensuring smooth integration into production. The Manufacturing Process Engineer will work closely with internal stakeholders and external suppliers to ensure equipment and processes meet performance, quality and cost expectations. The role also plays an active part in continuous improvement across the CCM area, driving improvements in yield, throughput, cost and workplace organisation. This includes applying structured CI methodologies, supporting capital improvement proposals and helping build the systems and standards required for repeatable, high‑volume manufacturing. Working closely with the Principal Engineer and production teams, the Manufacturing Process Engineer captures, stabilises and continuously improves process knowledge to support scalable CCM manufacturing.

Responsibilities

• Support industrialisation and continuous improvement of CCM manufacturing processes.
• Define and maintain manufacturing standards including SOPs, process parameters, routing and engineering documentation.
• Support introduction of new equipment and automated systems into production, including equipment specification, supplier engagement, FAT/SAT, commissioning and production handover.
• Deliver process improvement activities focused on yield, throughput, quality, cost reduction and process stability.
• Provide hands‑on technical support to production, including troubleshooting, root cause analysis and process optimisation.
• Support engineering change management, including FMEA, process updates and controlled implementation of changes.
• Support factory layout, workflow optimisation and workplace organisation activities.
• Contribute to CapEx projects and manufacturing improvement initiatives.
• Maintain accurate manufacturing documentation and support knowledge sharing across the team.
• Work collaboratively with engineering, production, quality, maintenance teams and external suppliers to support manufacturing objectives.
