Scope

We are seeking a highly motivated Principal Scientist specialising in Single-Cell RNA TCR data analysis and experience in deep learning structural biology and immunology. This role will be a key contributor alongside a team of talented computational biologists and experimental scientists in the Oncology Translational Research Department. The Scientist will be responsible for combining single-cell TCR sequencing analysis with advanced machine learning approaches to predict TCR:peptide-MHC interactions characterise tumor-reactive T cell repertoires and develop predictive biomarkers for therapy response in precision immunotherapy programs.

In this role You will:

• Lead comprehensive analysis of single-cell RNA-seq with paired TCR sequencing including clonotype identification repertoire diversity and integration with transcriptional phenotypes; building and maintaining pipelines in Python.
• Work with deep learning architectures (transformers graph neural networks CNNs) for TCR:pMHC interaction prediction using sequence and structural features.
• Collaborate closely with the Oncology Translational Research team members immunologists and AI/ML engineers to translate TCR insights into clinical biomarkers.
• Develop predictive biomarker signatures correlating TCR features with clinical outcomes and support companion diagnostic development.
