Data Science Lead

Job summaryWest and North London Integrated Care Board (WNL ICB) are recruiting a Lead Data Scientist to build out our in-house data science capability at an exciting time in our development. Through our investment in One London, we hold linked, person-level data spanning primary care, hospitals, mental health, community and social care for our population, a rich asset to model from. We've recently migrated our analytics platform to Snowflake, so you'll be shaping a modern, cloud-native stack from an early stage.As an experienced technical leader and researcher, you'll use advanced predictive and prescriptive methods (causal inference, stochastic simulation, Bayesian hierarchical modelling, machine learning and more) to tackle real strategic and operational questions, e.g., forecasting the financial and population health impact of a new service before it launches, building risk models to identify who could benefit from proactive care, simulating the impact of a business case before money is committed, and evaluating whether the care models we've introduced are actually working. You'll productionise these into tools used across the WNL health and care system, impacting real-world strategic, operational and clinical decision-making. You'll play a key role in ensuring these new data and technologies are used responsibly and ethically to ensure this innovation does not perpetuate existing health inequalities and must feel confident promoting these principles.Main duties of the jobIndependently delivering end-to-end data science projects yielding actionable insights and tools in production that enable users to tackle real-world strategic and operational problems. Considering user needs, data quality and management, user experience and engagement, deployment, and making best use of statistical and machine learning methods.Rigorously applying appropriate advanced statistical and data science methodologies to generate robust and reliable insights communicated with appropriate levels of uncertaintyMaintaining knowledge of a broad range of advanced statistical methodologies to identify and apply the most appropriate technical solution to a given problem, alongside a modelling specialism in line with the seniority of the roleAdvanced use of open-source analytical tools (including R or Python) to develop and deploy (Snowflake, Docker, Github Actions) models and applications, and to assess and monitor model outputsSet technical standards, actively contribute to high-level architectural decisions and identify development opportunities for yourself and those around you and adopt innovative practices learned from the wider analytics communityMatrix management and coaching of senior data scientists to deliver advanced models and productionise tool.About usWho we areWe are NHS West and North London.
