What does a data engineer do?

A data engineer is responsible for designing, building, and maintaining the infrastructure required to collect, store, and analyze data. They create and manage data pipelines, implement ETL/ELT processes, and ensure data quality, security, and accessibility. Data engineers work closely with analysts, scientists, and product teams to deliver usable and reliable datasets.

As part of a data engineering company or internal team, data engineers play a critical role in powering business intelligence, real-time analytics, and machine learning models through robust, scalable data engineering solutions.
