About Discovery
Discovery’s core purpose is to enhance and protect people’s lives. It does this through breakthrough product designs that harness incentives to encourage people to make healthier lifestyle choices. Healthy behaviour leads to lower claims, higher margins, and lower lapses. These savings are shared with our clients which in turn leads to a healthier society, improved productivity, and a reduced healthcare burden. One of Discovery’s core assets is its large and diverse data, covering health, wellness, driving, investments, and life insurance. This forms the basis for our shared value model, along with innovation, risk management and operational efficiency improvements. Discovery’s energetic and motivated analytical teams make this happen.
About the Data Science Lab
The Data Science Lab applies predictive analytics, machine learning, big data, and operations research skills to run and to support key projects for the Discovery Group and for the individual Discovery business units, including the health, life, and short-term insurance businesses. We work across operational, clinical, wellness, financial, customer service, sales, and behavioural science areas. We use and create state-of-the-art tools and work with terabytes of structured and unstructured data within a big data environment.
About the Position
The key purpose of the Data Analyst role is to design and implement analyses, and communicate findings and insights to support the work of our data science team within the Group Data Science Lab. This team focuses on the development and evaluation of Natural Language Processing (NLP) and Large Language Model (LLM) systems. The role requires working with both structured and unstructured data, collaborating closely with a team of data scientists and engineers, and fostering strong relationships with operations and business stakeholders to ensure alignment between the data science work and business objectives.
