About the role
We are looking for a Senior Data Scientist (Biostatistics) to support our clients in advancing their statistical modelling capabilities.
In this role, you will work closely with client-side biostatisticians and cross-functional teams to refine modelling approaches, design robust and scalable R-based processes, and support the deployment of statistical models as production-grade software on cloud infrastructure.
This is a highly collaborative and consultative position where you'll act as a technical expert and advisor—helping clients bridge statistical science with modern engineering best practices. You'll ensure models are reproducible, maintainable, and production-ready, while enabling teams to adopt more efficient and scalable ways of working.
