• Draft SOP and reports for the analysis of hormone molecules in clinical samples
• Work and communicate with the biosensor R&D team for sensing optimisations

• A master's or Ph.D. degree in chemistry, analytical chemistry or related disciplines with a background in biological science and statistics. Postdoctoral experience (university or industrial) will be a plus for this position. Right to work in the UK

• Proficiency in analytical chemistry techniques, including mass spectrometry, LC-MS/MS and others
• Experience and deep understanding in sample extraction/separation in clinical samples
• Experience working with lipids, steroid hormones or steroid-like molecules using mass spectrometry
• Expertise in analytical protocol development and analysis

• Knowledge of ICP-MS
• Knowledge in the characterisation of different human fluids

• We are a young company of highly motivated individuals who work together in pursuit of our mission and impact. Each one of us is driven by the pursuit of excellence, supporting one another while taking ownership of our outcomes, and exploring uncharted territories
