Data engineers and backend engineers are two important roles in the tech industry, and although they have some similarities, they also have distinct differences. In this blog post, we will explore what each role does, their responsibilities, the technologies they use, and whether they can be substituted for each other in a startup.
Data engineer
A data engineer is responsible for designing and building the infrastructure that allows data scientists and analysts to access and work with data.
This includes designing and maintaining the data pipelines that move data from various sources into a central repository, as well as designing and implementing data storage solutions. Data engineers also work on data quality and data governance to ensure that the data is accurate and can be trusted. They use technologies such as Hadoop, Spark, and SQL to extract, transform, and load data into data warehouses.
Backend engineer
On the other hand, a backend engineer is responsible for the server-side of web and mobile applications.
They work on developing and maintaining the APIs (Application Programming Interface) that allow the front-end of the application to communicate with the back-end. Backend engineers also work on database design and management, and they use technologies such as Node.js, Java, and Python.
Responsibilities and compensation
In terms of responsibilities, data engineers focus on data infrastructure while backend engineers focus on server-side logic and APIs. Data engineers ensure that data is available, accurate and reliable while backend engineers ensure the server-side is working correctly and efficiently.
In terms of compensation, according to Glassdoor, the average salary for a data engineer is $115,000 per year and the average salary for a backend engineer is $105,000 per year. However, compensation also depends on factors such as location, company size, and years of experience.
In a startup, it may be possible to substitute a data engineer for a backend engineer, but it would depend on the specific needs of the startup. If the startup's primary focus is on data-driven decision making and analytics, then a data engineer would be more critical. However, if the startup's primary focus is on building the server-side of the application, then a backend engineer would be more critical.
Conclusion
In conclusion, data engineers and backend engineers are two distinct roles in the tech industry. While they have some similarities, they also have distinct differences in terms of responsibilities, technologies used, and compensation. In a startup, it depends on the specific needs of the startup, whether or not they can be substituted for each other.
