What Does a Big Data Engineer Do?

Big Data Engineers are technical experts who specialize in managing and interpreting large and complex datasets for companies across various industries.

Their primary responsibility is to design, construct, install, and maintain large-scale data processing systems.

They often have to deal with systems that manage and process vast amounts of data, hence the term ‘big data’.

Big Data Engineers work closely with Data Scientists to convert their data models into a production-level system that can handle the required scale of data.

They also develop, construct, test, and maintain architectures such as databases and large-scale processing systems.

Their role involves ensuring data accuracy and accessibility by creating secure, high-performance, and scalable databases and systems.

They often need to re-engineer a company’s existing data infrastructure to meet new challenges or accommodate growth.

Big Data Engineers are also responsible for developing and implementing data cleaning and governance procedures to ensure data integrity and quality.

They may also be called upon to provide technical leadership and training to more junior team members.

In some organizations, Big Data Engineers also take on the task of data extraction, transformation, and loading (ETL) from different sources into the system.

They need to work closely with the IT and business sectors of a company to understand their needs and translate them into technical requirements.

 

Big Data Engineer Qualifications and Skills

Big Data Engineers utilize an extensive range of technical skills, data analysis abilities, and industry knowledge to design, build, and maintain complex data architectures, databases, and processing systems, including:
