About the Role
We are hiring an experienced synthesis and characterisation material scientist to run exploratory and targeted material synthesis, characterise structure and properties, and feed clean, well-documented data back into the AI-driven discovery loop. The role spans from the first synthesis of a novel composition through to the characterisation that tells us whether it is worth pursuing. We are interested in people from solid-state and inorganic chemistry to metallurgy provided they are strong hands-on synthesists with real characterisation depth. You will be joining a small, highly ambitious team of world-renowned engineers, AI researchers, and materials scientists.
Responsibilities
- Synthesise inorganic, intermetallic and alloyed materials using one or more established routes (for example solid-state reaction, arc-melting and melt processing, powder metallurgy, flux and crystal growth, solution methods, thin-film deposition).
- Determine structure and phase composition by X-ray diffraction, including powder XRD with Rietveld refinement and, where relevant, single-crystal methods.
- Characterise microstructure and chemistry using electron microscopy and related techniques (for example SEM-EDS/EBSD, TEM/STEM).
- Measure functional properties that determine commercial potential of the materials.
- Run exploratory synthesis campaigns guided by computational and AI models, and feed structured experimental results back to improve them.
- Develop reproducible, well-documented experimental workflows and contribute to the lab's data standards and its move toward higher-throughput.
- Collaborate across the computational, machine learning, and experimental teams to prioritise and de-risk the most promising compositions.
Requirements
- PhD in Chemistry, Materials Science, Metallurgy, Physics, Chemical Engineering, or a closely related field.
- Strong hands-on experience synthesising inorganic, intermetallic, or alloy materials by one or more established routes.
- Demonstrated expertise in materials characterisation, in particular X-ray diffraction and phase analysis, together with at least one of electron microscopy, thermal analysis, or property measurement.
- A working understanding of structure, phase stability, and structure-property relationships in complex inorganic or metallic systems.
- Comfort with Python or a similar language for data handling and analysis.
- Excellent documentation, communication, and cross-disciplinary collaboration, evidenced by a research or development track record.
