Primary Responsibilities:  

   •      Analyze, review and interpret complex data through the development of case-studies, enabling the data to tell a story. 
   •      Build and maintain production-ready machine-learning models. 
   •      Identify drivers of patterns / behaviors uncovered in data and use these to explain business trends. 
   •      Contribute to the design and realization of analytical based tools/assets to identify and monitor non-standard claim patterns. 
   •      Engage with subject-matter experts to explore business problems and design solutions. 
   •      Present analysis and interpretation for both operational and business review and planning. 
   •      Support short and long term operational and strategic business activities through the use of data and develop recommended business solutions through research, analysis and implement when appropriate. 

You will be rewarded and recognised for your performance in an environment that will challenge you and give you clear direction on what it takes to succeed in your role, as well as providing development for other roles you may be interested in.

Required Qualifications:

   •      Advanced degree in Statistics, Physics, Mathematics, Engineering or similar analytic domain with a significant quantitative aspect. 
   •      Substantial hands-on experience in AI/ML using contemporary tools such as PyTorch.

We believe everyone-of every race, gender, sexuality, age, location and income-deserves the opportunity to live their healthiest life.
