What is the role of the Data Engineer?

Udacity role of Data Engineer

Data engineers play a vital role in any enterprise data analytics team and responsible for managing, optimizing, overseeing, and monitoring data retrieval, storage, and distribution throughout the organization

Data engineers are also responsible for finding trends in data sets and developing algorithms to help make raw data more useful to enterprises. One should have a significant set of technical skills, including a deep knowledge of SQL database design and multiple programming languages. However, data engineers also need to be proficient in communication skills to work across departments to understand what business leaders want to gain from the company’s large datasets.

Data engineers are often responsible for building algorithms to help give easier access to raw data, but to do this, they need to understand the company’s or client’s objectives. It’s important to have business goals in line when working with data, especially for companies that handle large and complex datasets and databases.

Data engineers also need to understand how to optimize data retrieval and how to develop dashboards, reports, and other visualizations for stakeholders. Depending on the organization, data engineers may also be responsible for communicating data trends. Larger organizations often have multiple data analysts or scientists to help and understand data, while smaller companies might rely on a data engineer to work in both roles.
