Main duties of the job
We are seeking a Senior Population Health Data Scientist to lead complex analytics and drive system-wide transformation across Guy’s and St Thomas’ NHS Foundation Trust.

Using tools like Python, R, SQL, and Power BI, you will extract and analyse data from multiple care settings to produce actionable insights, support prevention, and drive evidence-based decision-making. You’ll also design KPI frameworks, evaluate impact, and communicate findings to senior leaders, clinicians, and wider stakeholders.
This role demands strong leadership in capability building, project delivery, stakeholder engagement, and analytical strategy. You’ll build a culture of continuous improvement, lead training initiatives, mentor staff, and contribute to a technical community of practice.
With a focus on governance, quality, and innovation, you’ll ensure data use is ethical, reproducible, and impactful — influencing resource allocation, investment decisions, and care transformation at all levels
