As Materials & Process Development Engineer, you will be responsible for shaping and delivering the company’s advanced materials and WAAM (Wire Arc Additive Manufacturing) capability. The role spans R&D, process industrialisation, and compliance, positioning you at the interface between product innovation, quality assurance, and manufacturing readiness. This is a technically hands-on, strategically important role, ideal for someone with a strong foundation in metallurgy, a deep understanding of additive processes, and the drive to push new materials and methods into production. You will play a critical role in building internal infrastructure, guiding qualification pathways, and ensuring external technical credibility with customers, auditors, and partners Roles Responsibilities - Process & Technology Development: Provide technical support in the development, optimisation, and qualification of WAAM processes across a range of structural alloys. Act as a focal point for material-related manufacturing strategies, driving repeatability, build quality, and throughput improvements. - Materials Introduction & Qualification: Support and lead cross-functional efforts to introduce new materials into the Additive Manufacturing portfolio, from feasibility to qualification. Coordinating internal trials and external validation activities to ensure materials are fit for purpose and compliant with customer and regulatory expectations. - Internal Capability Building: Establish, develop and maintain in-house materials characterisation and quality control infrastructure, including sample preparation, metallography, and optical microscopy. Define and implement repeatable procedures that support both R&D and production, enabling scalable, traceable evaluation of material quality and process performance. - Governance & Compliance: Support and maintain systems aligned with ISO 9001 and engage directly with class societies and third-party auditors. Ensure that documentation, traceability, and technical reporting meet the standards required for regulated applications (e.g., marine, defence). - Training & Knowledge Transfer: Mentor engineers and technicians in the application of WAAM techniques, metallurgical analysis, and equipment use. Drive continuous upskilling across the team to embed best practice in process execution and quality control. - Research & External Engagement: Represent the company in technical forums and conferences. Take ownership of collaborative R&D efforts that align with strategic goals and contribute to the company’s technical reputation in the additive manufacturing field. - Degree (MSc or higher, PhD preferred) in Materials Science, Manufacturing Engineering, or a related discipline - Minimum of 3 years of experience in Materials Science, Manufacturing Engineering, or a related discipline - Proven track record in additive manufacturing process development, particularly WAAM or DED - Strong technical grounding in welding metallurgy and materials characterisation techniques - Experience working within a certified QMS (ISO 9001) and engaging with certification bodies - Ability to translate R&D outcomes into practical, scalable solutions for production - Excellent problem-solving skills and a methodical approach to troubleshooting manufacturing issues.
