A Machine Learning Developer designs, develops, and implements machine learning systems. They run machine learning tests and experiments, perform statistical analysis, and fine-tune test results to optimize system performance. The developer understands and transforms complex datasets into solutions, often using predictive models. They must keep up-to-date with the latest technology trends, understand and apply machine learning algorithms effectively. They also work closely with other teams to understand requirements and goals, and to integrate machine learning capabilities into applications and services. They must have strong programming, analytical, problem-solving skills, and a deep understanding of machine learning principles.
