Lead Materials Engineer

We are seeking a Senior Materials Engineer to lead the development and scaling of materials and processes for our micro-tubular SOFC stacks. In this role, you will own the translation of laboratory methods into robust, repeatable processes: ensuring performance, durability, and manufacturability as we move from prototypes to commercialisation.

You will act as a technical leader in the R&D team, mentoring junior colleagues, coordinating with other disciplines, and taking responsibility for the success of materials-related work packages. Your expertise will directly shape our ability to deliver our novel fuel cell systems at scale.

Your tasks

• Lead the design and optimization of materials and deposition processes for electrolytes, electrodes, and coatings
• Establish and refine manufacturing protocols and SOPs to ensure reproducible fabrication
• Guide experimental campaigns and ensure results are analyzed, documented, and translated into best practices
• Collaborate with other teams to link materials and processes with fuel cell performance and durability
• Supervise and mentor technicians, interns, and junior engineers, ensuring efficient lab execution and professional growth
• Take ownership of project deliverables related to materials and process engineering, including technical reporting for internal and external stakeholders
• Contribute to IP recognition and process innovation

Your qualification 

• MSc or PhD in Materials Engineering, Chemical Engineering, Process Engineering, or related field
• 5+ years of experience in materials development, ideally in an industrial or applied R&D environment
• Strong track record in process development: from lab methods to stable, scalable protocols
• Expertise in materials synthesis, deposition methods, and thermal processing
