About this job

As a Data Scientist you will have exposure to many aspects of the business, and make direct impact to the bottom line. You will be accountable for interfacing with various teams throughout the business to derive a deep understanding of underlying phenomena that impact portfolio performance, develop better features to improve the performance of our predictive models, and better understand the links between client interventions and behaviour.

  • Automate analytics tasks to help us improve productivity and set ourselves up for scale. 
  • Design and develop models of our real world systems and client behaviours to help inform our decision making. This includes, but is not limited to, forecasting, simulating products or systems, testing decline strategies, and optimising client experience.
