What is a Data Engineer?

A data engineer plays a vital role in the data lifecycle. Data engineering is designing and building systems to collect, store, and analyze data at scale[1].

Data engineers do more than just gather, prepare, and transform data. Their responsibilities also include:

• Security: Protecting data and ensuring compliance.
• Management: Overseeing data workflows and processes.
• Orchestration: Coordinating how data moves and is processed across different systems.
• Architecture: Designing data systems and infrastructure.
• Software Engineering: Creating and maintaining software solutions for data processing.
• Operators: Managing operations to ensure reliability.
• Methods, Tools, and Services: Using various technologies to improve data processes.
