Data Scientist

We need a hands-on Contract Senior Data Scientist to design, build, and ML models that drive commercial performance. You will take ownership of the full life cycle: framing problems, building models, and deploying them reliably into production.

This assignment requires an expert Data Science practitioner who can take complex business problems through the full life cycle independently: framing the problem, exploring data structures, building/validating models, and ensuring reliable production deployment. You will collaborate closely with product, commercial, and engineering teams to deliver robust, outcomes-focused solutions.
