About the role St John WA has been serving the Western Australian community since 1922. Our organisation has grown into an integrated healthcare provider, connecting people across WA to lifesaving emergency services, urgent care, and health education.

We are a not-for-profit organisation, and we are committed to making a positive impact on the safety, wellbeing, and health of everyone, no matter where in WA they live. Our services are powered by more than 8,000 dedicated employees and volunteers who bring care, skill, and compassion to every corner of the state.

This position sits within the Data Science and Analytics team at St John WA which uses data to help the organisation make informed decisions to better serve the community.

The Data Science and Analytics team consists of four units: Operational Analytics, Strategic Analytics, Data Insights, and Data Science.

Applications are encouraged from experienced data science professionals keen to bring their industry or academic experience to a community focussed organisation and see their work deliver real-world impact.
