office workspace

The modern business environment is characterized by an exceptional volume of data generated at an increasing pace. In this era of information overload, organizations recognize the need to extract meaningful insights from their data to stay competitive and drive growth. This is where Business Intelligence (BI) engineers become integral to the decision-making processes.In our article, you will learn about the BI engineer
role, the key responsibilities they shoulder, and the skills essential for success.

Who is the BI engineer?

A BI engineer is a skilled professional responsible for transforming raw data into meaningful insights that support decision-making processes. BI engineer uses a combination of technical expertise and business insights to design and implement BI solutions. The primary objective is to create systems that gather, process, and present data in a way that allows organizations to extract valuable information and gain a competitive advantage. BI engineers often work with various tools and technologies, including data warehouses, ETL (Extract, Transform, Load) processes, data visualization tools, and reporting platforms. They collaborate with different departments within an organization to understand their data needs, design efficient data models, and develop dashboards and reports that offer actionable insights.

Hence, the BI engineer plays a crucial role in helping organizations leverage their data to make informed decisions, optimize processes, and identify trends or patterns that can impact business performance. With the increasing importance of data-driven decision-making in today’s business landscape, the role of BI engineer is essential in bridging the gap between raw data and strategic insights, empowering businesses to stay competitive and responsive to market dynamics. As of January 11, 2024, the average hourly pay for a BI engineer in the United States is $53.79.

The difference between BI and ETL developers

In our previous article, we discussed the role of the ETL developer. First, let’s understand the difference between ETL and BI engineers in the ever-evolving world of data analytics.

BI engineers and ETL engineers both have crucial roles in the field of data management and analytics, but they have distinct responsibilities and focus areas within the data pipeline. ETL developer focuses on moving data from source systems to a data warehouse for analysis. On the other hand, the BI engineer’s role is to analyze data to support decision-making through dashboards, reports, and data visualization.

Therefore, ETL developers focus on the back-end, managing the extraction, transformation, and loading of data from source systems to warehouses. While BI engineers concentrate on the front-end aspects of the data pipeline, crafting visually compelling dashboards and reports.
