A Model Fitting and Prediction developer designs, builds, and maintains statistical and machine learning models. They gather and analyze large sets of data, use algorithms to identify patterns and trends, and adjust models for best fit. They then use these models to make accurate predictions about future occurrences. They often work with data scientists and other stakeholders to understand business needs, and translate these into technical requirements. Their role also involves continual model testing and tuning to ensure accuracy, and they may also present their findings to non-technical stakeholders. They need strong programming, statistical, and problem-solving skills.
