Job Description

This is an exciting opportunity to take a senior, hands-on data science role within a new enterprise data science function.

As a Senior Clinical Data Scientist, the post-holder owns the full health data science lifecycle from problem to solution, delivering pilots that aim to produce measurable improvements in clinical and operational KPIs.

  • Take individual delivery ownership of data science pilots across the full lifecycle – problem definition, diagnosis, solution design, experimentation, implementation support, and outcome measurement – working autonomously and accountable for movement in target KPIs
  • Apply modern machine learning, statistical, causal inference, and experimental methods to clinical and operational problems, recognising that a model is one option among several, not the default
  • Act as a domain expert, using a clinical background to frame real-world clinical and operational problems and to validate that outputs are clinically and operationally meaningful
  • Work with the data and software engineering team to productionise pilots and to monitor the impact and safety of deployed decision-support tools
  • Take the analytical lead on highly complex and contentious healthcare data, devising methods, setting data-quality and performance KPIs, and making evidence-based recommendations to stakeholders
  • Engage and influence clinical, operational, and technical stakeholders, and support more junior analysts and data scientists through mentoring and capability-building
