Data engineer responsibilities

The Data Engineer’s job entails keeping an optimal pipeline architecture in place and performing various other tasks and responsibilities. Typical duties and obligations of a data engineer position may include:

  • Assembling huge, complex collections of information that fulfill non-technical and functional business demands.
  • Identifying, developing, and implementing internal process improvements, including re-designing infrastructure for increased scalability, improving data delivery, and automating routine procedures.
  • Build the infrastructure required to extract, transform, and load data from various data sources using AWS and SQL technologies.
  • Analyze data from the business to make more informed decisions with analytical tools that utilize the data pipeline and provide practical insight into important company performance indicators such as operational efficiency and consumer acquisition.
  • Working with stakeholders such as data, design, product, and executive teams to solve data-related technical difficulties.
  • Working with executives, product, data, and design teams to assist them with their data infrastructure demands while resolving technical difficulties.

Data engineering roles

Data engineers are in charge of overseeing analytics in a company. Data engineers give your data velocity. It’s difficult for firms to make immediate decisions and figure out fraud, attrition, and customer retention metrics. For example, data engineers may assist an e-commerce firm in determining which products will have the most demand in the future. Similarly, they might be able to target varied buyer personas and provide more customized experiences to their clients by using them.

A data engineer’s job may vary from day to day, depending on the sort of firm they work for it. Data engineers may be categorized into a few groups based on their duties:

  • Generalist
  • Pipeline-centric
  • Database-centric

Generalist

A data engineer works on a small team most of the time. Without a data engineer, data analysts and scientists won’t be able to analyze anything because they don’t have any data to work with it. A data scientist needs a dedicated first member of the team.

When a firm has only one data engineer, they are frequently forced to take on more end-to-end duties. For example, a generalist data engineer may be required to do everything from ingesting the data to processing it through the final analysis. Because small teams and businesses don’t have many users, scalability engineering isn’t as essential. This is an excellent area for a data scientist interested in moving into data engineering.

Pipeline-centric

A pipeline-centric data engineer is required for mid-sized businesses with complicated data science requirements. A pipeline-centric data engineer will collaborate with teams of data scientists to convert raw data into an analyzable form. This requires an extensive understanding of distributed systems and computer science.

Database-centric

A data engineer who focuses on databases is concerned with setting up and populating analytics databases. This includes some pipeline development, although more database tweaking is necessary to enable rapid analysis. To get data into warehouses, you must perform ETL work. A typical example of a company employing a database-centric data engineer would be one with many data analysts that have their data strewn across numerous databases.
