The Machine Learning (ML) Engineer focuses on coding, deploying, and maintaining large-scale machine learning models throughout their lifecycle. By combining software engineering principles and data science/machine learning knowledge, the ML Engineer develops the data processes that make ML models generally available for use in products for end-users and customers. The ML engineer should understand machine learning algorithms, have experience in software engineering and various programming languages, including Python, SQL, and Apache Spark. An understanding of latest cloud technologies is imperative for the development and deployment of ML solutions as well. The chief contribution of the ML Engineer is their ability to optimize machine learning solutions for performance and scalability.
