What you will do

• Own analytical work from scientific problem framing and experimental design through analysis, modelling, validation, and interpretation.
• Investigate how measurement processes, sample properties, and experimental conditions affect observed data.
• Prototype, develop, and evaluate signal-processing, preprocessing, feature-extraction, and modelling approaches for complex experimental datasets.
• Identify technical variation and artefacts, assess their impact on data quality, reproducibility, and downstream conclusions, and develop correction or compensation methods.
• Collaborate with experimental scientists and engineers to design targeted experiments, improve data generation, and resolve uncertainty.
• At Lead level, define methodological standards, guide complex technical decisions, and build the team’s ability to reason about measurement systems and experimental evidence.

Requirements

• PhD in Physics, Applied Physics, Engineering, or a related quantitative or experimental discipline; a Master’s degree with substantial relevant experience is also considered.
• Strong experience analysing physical signals or complex measurement-based datasets.
• Sound understanding of signal processing, statistical analysis, and machine learning.
• Ability to design investigations, work with raw experimental data, and assess alternative explanations for observed patterns.
• Strong scientific programming skills and experience developing reproducible analytical workflows.
• Evidence of independently delivering complex scientific analyses. Lead candidates must also demonstrate methodological influence across projects and technical mentoring.

Nice to have

• Experience in spectroscopy, photonics, sensor systems, analytical chemistry, or related fields.
• Prior Raman or FTIR expertise.
