Principal Data Scientist jobs in Sheffield

You will join a dedicated and collaborative team at the centre of one of DWP's highest priority initiatives: the Health Transformation Programme. This position places you at the forefront of redesigning key health related services, working with some of the largest and most complex datasets available in the UK to generate high quality insights that improve outcomes for thousands of people.

You will work across a variety of complex analytical problems, owning experimentation end-to-end—even when ideal conditions such as user randomisation or high statistical power are not present.

You will work on modernizing authentication and login experiences across multiple consumer applications, helping drive growth through high-quality user experience, experimentation, and data-driven decision making. This is a collaborative role, working closely with engineers, product managers, and cross-functional partners in a fast-paced environment.

You will work on real production problems rather than research-only work, owning models from first iteration through to live deployment.

You will collaborate closely with other data scientists, data engineers, and DevOps, with the freedom to shape how GenAI and ML are used across the platform.

You will define technical strategy, design scalable data systems, mentor senior engineers, and partner closely with product, engineering, analytics, and business leaders to transform strategic goals into robust, data-driven solutions.

You will work closely with other engineers, product stakeholders, and customers to design, build, and operate production-grade data systems, focusing on reliable ingestion, transformation, and exposure of data through APIs and product integrations.
