Position Summary:
We are seeking a highly motivated Postdoctoral Researcher with experience in X-ray Crystallography to join an ambitious, data-driven drug discovery program at the interface of structural biology, chemical biology, and artificial intelligence. This role will play a central part in hit characterisation for LIGAND-AI, generating high-quality protein-ligand co-crystal structures that directly inform structure-based drug discovery research programs, the development of machine learning models and enable international benchmarking challenges.

The Postdoctoral Researcher will focus on structure determination of protein-ligand complexes spanning key biological pathways including epigenetics, ubiquitin signalling, gene regulation, and DNA repair. These structures will not only drive internal hit validation and SAR development but will also feed into global open science efforts and benchmarking initiatives such as CASP, helping define the next generation of AI-enabled drug discovery.

This is an exciting opportunity to work at the frontier of structural biology and AI, where experimentally rigorous crystallographic data are treated as first-class training data for machine learning. The successful candidate will contribute to a growing portfolio of high-impact structures designed to stress-test, validate, and improve LIGAND-AI predictions in real-world drug discovery settings.

The Postdoctoral Researcher will be embedded in a highly collaborative early-stage drug discovery team, working closely with medicinal chemists, computational scientists, machine learning experts, automation engineers, and biochemists. Together, the team integrates structure, chemistry, and data science to rapidly advance hit matter and generate benchmark-quality datasets with broad community value.
