The responsibilities of a data engineer imply that the person in this role designs, creates, develops, and maintains systems and architecture that allow them to collect, store, and interpret data. Hence, the systems and architecture need a professional who can keep the data flow from source to destination clean and eliminate any bottlenecks to enable data scientists to pull out insights from the data and transform it into data-driven decisions. In this respect, the purpose of the blog is to explain what is a data engineer, describe their duties to know the context that uses data, and explain why the role of a data engineer is central.
What Does a Data Engineer Do?
Data engineers play a paramount role in the organization by transforming raw data into valuable insights. Their roles are expounded below:
- Acquire Datasets: It is about acquiring datasets that are focused on defined business objectives to drive out relevant insight.
- Support Data Streaming: Build systems that allow the flow of required data seamlessly in real-time for analysis.
- Implement analytics systems: Install and tune such systems for analytics and business intelligence operations.
- Create Business Reports: Formulate reports that will be helpful in deciding company advisors.
- Design algorithms transforming raw data into actionable information for strategic decisions.
- Design and maintain pipelines: Bring to life the robust architectures of pipelines with efficient data processing and testing.
- Collaborate with Management: Management shall collaborate, understanding the objectives while aligning data strategies.
- Data Validation and Tools: Design methods and tools that guarantee the accuracy of data and enable its analysis.
- Compliance Enforcement: Enforcing of policies related to data governance and security toward protecting the integrity of the data.
For small companies, the data engineer holds a generalist position where he basically does all it. In big organizations, they would focus on pipeline building or play a Data Warehouse Manager.
