The Testing Operations division of NHS Test and Trace runs the national C19 Testing Programme. Come to build our next generation of models and tools.

The Testing Operations division is responsible for the day to day running of the national testing programme. We currently sit within Test and Trace, but are soon to become part of the UK Health Security Agency. Demand and Capacity Modelling provides the authoritative view of short, medium and long-term demand and capacity for testing, in order to support strategic planning, procurement and operational decision-making.
Demand and Capacity Modelling is a mixed profession team of analysts, data scientists and developers, working with stakeholders across Test and Trace and across government on influential and exciting analysis over all time scales, from next-day operational decisions to long term planning scenarios and value for money.
We’re looking for experienced modellers to help build the next generation of models and tools so we can strengthen our existing modelling capabilities.

Role requirements
