About the role
About Relation Relation is a sector defining TechBio company developing transformational medicines, with technology at our core. Our ambition is to understand human biology in unprecedented ways, discovering therapies to treat some of life’s most devastating diseases. We leverage single-cell multi-omics from patient tissue, functional assays, and machine learning to drive disease understanding, from cause to cure. We are scaling rapidly and building a team of exceptional individuals to push the boundaries of drug discovery. You will work in highly interdisciplinary teams where biology, computation, and engineering come together to solve complex problems that have not been solved before. Our state-of-the-art wet and dry labs in the heart of London are designed to accelerate this integration and translate insight into impact. We are committed to building diverse and inclusive teams. Relation is an equal opportunities employer and does not discriminate on the basis of gender, sexual orientation, marital or civil partnership status, gender reassignment, race, colour, nationality, ethnic or national origin, religion or belief, disability, or age. By joining Relation, you will help define how medicines are discovered and deliver meaningful impact for patients. The opportunity Join our machine learning group as a Research Engineer and help drive the development, deployment, and scaling of ML and computational systems across the company. You’ll work at the intersection of research and engineering—improving research workflows, supporting rapid experimentation, and enabling teams to push the limits of modern ML. You’ll collaborate with machine learning scientists, data scientists, platform engineers, and other domain experts across the organisation. Depending on priorities, you may work within a specific ML team or operate in a cross-functional capacity. Based at our wet/dry lab and headquarters in central London, you’ll tackle challenges involving large datasets, complex models, and high-performance compute. Your work will strengthen our training and inference pipelines, improve our software foundations, and optimise our hybrid on-prem/cloud environment, which includes dedicated DGX clusters and collaboration with partners like NVIDIA. This role offers a chance to shape the systems and tools that power cutting-edge ML research. Day to day, you will Work with interdisciplinary teams to solve challenges across data engineering, ML engineering, and software engineering. Build and improve data processing, transformation, and loading systems to support model training and inference at scale. Develop and maintain high-quality research and production codebases to enable rapid, reproducible experimentation. Advance our software engineering practices by optimising systems, streamlining pipelines, and improving robustness across workflows. Professionally, you will have BSc/MSc/PhD in CS/ML/Engineering (or related), 2+ years industry experience. Solid understanding of algorithms, data structures, complexity. Proficiency in Python with clean, maintainable coding practices. Familiarity with PyTorch and common scientific Python libraries. Solid understanding of ML fundamentals and modern deep learning. Experience training, evaluating, and iterating on models. Familiarity with AWS/GCP, Docker, Kubernetes, and CI/CD. Familiarity with orchestration tools (Airflow/Prefect) and model-serving frameworks.
