In today’s dynamic environment, a data engineer is responsible for managing the entire data engineering process. This encompasses gathering data from diverse sources and preparing it for use in downstream applications. Mastery of the various stages of the data engineering lifecycle is crucial, along with a knack for assessing data tools to ensure they deliver on multiple fronts: cost-effectiveness, speed, flexibility, scalability, user-friendliness, reusability, and interoperability.
