OVERVIEW
What is a Data Engineer?
听
A data engineer constructs information pipelines to get the right data from the best sources to the right people. They usually work with data scientists. In simple terms, they extract the data, transform it, and load it into a warehouse where it is accessible to experts. This is known as the ETL (extract, transform, load) process.
As an example, a data engineer might create an ETL process for a food ordering service. To work, the service will need to extract information from mobile apps, transform it into orders and payments, and load it so that the restaurants and delivery workers can deliver it to the customer.听
Such a system will collect lots of data, which means that different databases are needed to handle various kinds of information. These can include restaurant and user information, analytics, an order database with information about each transaction, and a customer service log with interactions between the app鈥檚 users and customer support agents.
A data engineer can work on a large development project or focus on a single aspect, such as creating a script that pulls data about user activity and organizes it so that marketing professionals can then use it to plan targeted offers. This job can also involve creating an interface that data scientists can use to access and organize the information.听
RESPONSIBILITIES
What Are the Job Duties of a Data Engineer?
The duties of data engineering roles can differ, but the jobs usually fall into three general categories:
Generalist data engineers
Generalist data engineers are more common in smaller companies with small teams. Sometimes, they might be both the data engineer and the data scientist.
Generalists usually handle the entire information pipeline from end to end. In some companies, however, the scope of the projects may be smaller, so they may have less work even though there are more responsibilities.听
Pipeline data engineers
A pipeline-centric data engineer is more common in mid-sized to large companies. Such organizations have more complex data needs. In this case, the pipeline-centric engineer works with the data science team to transform the company鈥檚 data into a form they can analyze. The engineer should have a deep knowledge of computer science to excel in this role.
Database data engineers
Database-centric data engineers are focused on setting up, inserting data into, and maintaining analytics databases. They work a little with pipelines, but most of their work has to do with creating the most useful databases and fine-tuning them for faster performance.听
Such engineers are most common in very large companies, where analytics databases have grown to the point where they need dedicated personnel to maintain them. This role involves a lot of highly specialized work, and therefore requires strong technical skills.
What Does a Data Engineer Do?
Data engineers have a wide range of responsibilities. Below are some of the most common ones:
- They develop, construct, test, and maintain data pipelines.
- They ensure that the architecture of the data pipelines is well-aligned with the business鈥檚 requirements.
- They gather data from different sources and organize it in one place.
- They develop algorithms to analyze the data and extract what is needed by the data scientists.
- They write automation scripts to handle repetitive tasks.
- Lead data engineers also play a managerial role, supervising their teams.
- They regularly work with data scientists and upper management to understand the organization鈥檚 data needs and create relevant strategies.
These are only some of the roles played by a data engineer. Depending on where they work, they might even be responsible for analyzing the data, in which case they double as data scientists.
EDUCATION & BEST DEGREES
What Education Does a Data Engineer Need?
Given the knowledge demands of this role, data engineers need to have a strong educational background. Usually, you start on this career path with a听bachelor鈥檚 degree in computer science,听software engineering,听information technology, or a related field.
You will also need extensive experience with听different programming languages, such as Java and Python. Knowledge of relational database management systems and how to design and manage them is also necessary, especially if you plan on being a database-centric engineer. In that case, you will have to learn database querying languages, like SQL.
In some cases, you may wish to pursue a听master's degree in data analytics听in order to gain additional experience and a higher-level understanding of data management technology, techniques, and real-world applications.
