How to Become a Data Engineer in 2023?

Data Engineering is typically a software engineering role that focuses deeply on data – namely, data workflows, data pipelines, and the ETL (Extract, Transform, Load) process.

According to reports by DICE Insights, the job of a Data Engineer is considered the top job in the technology industry in the third quarter of 2020. Companies from startups to the Fortune 500s are looking out for the best and brightest individuals to fill up the role of Data engineers beating out data scientists, cybersecurity analysts, and web developers.

However, several questions may arise for an individual. What is Data Science? What are the roles and responsibilities of a Data Engineer? How does one become a Data engineer, and what skills are required? And many more. Our primary focus in this article will be to answer all these questions and take you a step forward towards your dream of becoming a Data engineer. 

Let us first get a clear understanding of why Data Science is important.

What is the need for Data Science?

If we look at history, the data that was generated earlier was primarily structured and small in its outlook. A simple usage of Business Intelligence (BI) would be enough to analyze such datasets. However, as we progressed, data became complicated, more unstructured, or, in most cases, semi-structured. This mainly happened because data that is collected in recent times is vast and the source of collection of such data is varied, for example, data collected from text files, financial documents, multimedia data, sensors, etc. Business Intelligence tools, therefore cannot process this vast spectrum of data alone, hence we need advanced algorithms and analytical tools to gather insights from these data. This is one of the major reasons behind the popularity of data science.

The importance of data science is that it allows an individual to make better decisions by performing predictive analysis and finding significant patterns in the data sets.

It is interesting to note the key things that an individual can achieve with the help of data science:

  • What questions are to be asked when looking for the root cause of a problem.
  • An exploratory study of the given data set.
  • Data Modeling using multiple algorithms.
  • Data Communication and Data Visualization with the help of graphs, charts, dashboards, etc.

What is Data Science?

With the help of various scientific techniques and algorithms which help one to make predictions and map out data-driven solutions, data science is a field that helps an individual to generate inference and insights from structured, semi-structured, and unstructured datasets. It is an outcome of coordination between different statistical tools.

Data Science is the coordination of different statistical tools to determine meaningful inference and insights for better decision making.

How TO Become a Data Engineer

Let us go through an example to understand Data Science more deeply. This example will help us understand Data Science more clearly. Let us consider your sleep quality for instance.

The kind of sleep you have had last night is 1 data point for every day.

On day 1, you have had a good sleep for 8 hours, not much movement or sleep awakenings. That is a data point.

On day 2 however, you slept for 7 hours, which is an hour less than the previous day. That is another data point.

By collecting and analyzing these data points for a month, you will be able to gather inferences about your sleeping pattern for that given month. When do you sleep for more than 7 hours, which are the days, weekends or weekdays, when you have undisturbed sleep, etc.

If you continue tracking these data points for over six months or a year, you will be able to gather more information about your sleeping patterns; when do you have short-awakenings at night, when do you sleep the most, how long do you sleep on holidays, etc.

Analyzing more data points will therefore give you a more detailed insight into your study.

The spectrum of sources from which data is collected for the study in Data Science is broad. It comes from numerous sources ranging from surveys, social media platforms, e-commerce websites, browsing searches, etc. These data have been accessible to us because of the advanced and latest technologies which are used in the collection of data. Businesses benefit at large with these data collection and analysis as they allow organizations to make predictions and give insights about products so that they can make informed decisions, backed by inferences from existing data, which, in turn, helps in huge profit returns to such businesses.

What is the role of a Data Engineer?

Data Engineers are engineers responsible for uncovering trends in data sets and building algorithms and data pipelines to make raw data beneficial for the organization. This job requires a handful of skills, starting from a strong foundation of SQL and programming languages like Python, Java, etc. Apart from that, they are also required to have excellent communication skills to work with other departments and help achieve the goal of the enterprise.

Data Engineers are skilled professionals who lay the foundation of databases and architecture. Using database tools, they create a robust architecture and later implement the process to develop the database from zero.

As a Data Engineer, you must develop Dashboards, reports, and other visualizations and learn how to optimize retrieving data. They are also accountable for communicating data trends.

Let us now look at the three major roles of data engineers. These are as follows:

1. Generalists

They are typically responsible for every step of the data processing, starting from managing and making analysis and are usually part of small data-focused teams or small companies. This is considered a nice role for someone who wants to transition from a Data Scientist to a Data engineer.

2. Pipeline-centric

Pipeline-centric data engineers work with Data Scientists to help use the collected data and mostly belong in midsize companies. They are required to have deep knowledge of distributed systems and computer science.

3. Database-centric

In bigger organizations, Data engineers mainly focus on data analytics since the data flow in such organizations is huge. Data engineers who focus on databases work with data warehouses and develop different table schemas.

Let us now understand the basic responsibilities of a Data engineer.

What are the responsibilities of a Data Engineer?

The first step towards becoming a Data engineer is understanding the numerous responsibilities they need to undertake in their journey. Some of the most common responsibilities are as follows:

1. Analyzing and organizing raw data

Raw data is unstructured data consisting of texts, images, audio, and videos such as PDFs and voice transcripts. The job of a data engineer is to develop models using machine learning to scan, label and organize this unstructured data. This process helps convert the unstructured data into structured data, which can easily be collected and interpreted using analytical tools.

2. Building data systems and pipelines

Data pipelines refer to the design systems used to capture, clean, transform and route data to different destination systems, which data scientists can later use to analyze and gain information. The data pipelines allow businesses to collect data from millions of users and process the results in real-time. Data scientists and data Analysts depend on data engineers to build these data pipelines.

3. Interpretation of trends and patterns

A data engineer may also perform some of the responsibilities of Data Scientists or Data analysts depending upon the organization's size. They analyze datasets to find trends and patterns and report the results using visualization tools.

4. Evaluating business needs and objectives

The basic responsibility of a Data Engineer is to build algorithms and data pipelines so that everyone in the organization can have access to raw data. To achieve this, understanding the organization's business needs is necessary to build a data ecosystem serving the organization's objectives.

5. Preparing data for prescriptive and predictive modeling

Data engineers are responsible for completing the data. They have no missing values, are cleansed, and set out rules for the outliers.

6. Develop analytical tools

Some organizations hire Data engineers to develop analytical software to improve data accuracy and enhance customization. They achieve this through a programming language such as Java or C++. However, they are also asked to manipulate data using SaaS tools or build an analytical stack.

Let us now look at the popular companies that hire Data engineers.

What is the relationship and difference between Data Scientists and Data engineers?

In the past, most companies thought that Data Scientists were enough to perform their role and perform the tasks of a Data Engineer. This is one of the major reasons for the shortage in the recruitment of Data Scientists.

However, the volume and speed of data have driven companies to widely recognize both Data engineers and data scientists as two separate, distinct roles.

They are both required in an advanced analytics team of any organization. It is difficult to work in data science without a data Engineer by your side, even though both roles' priority skills and knowledge are different. Knowledge of Python and data visualization tools are common skills for both.

Let us now look at the key differences between a Data Scientist and a Data engineer in a tabular format.

As a Data Engineer, you have many options to choose from the most popular data tools, such as Kafka, Hadoop, Spark, MapReduce, Azure, etc. You can have the freedom to choose from what you are working on and what tools you are working with.

4. Technically Challenging

One of the most important Python functions that Data Analysts and Data Scientists use is read_csv. The function of this library tool is to read Tabular data stored in a text file which can later be explored and manipulated. This particular tool is one of the central parts of software engineering: creating abstract, broad, efficient, and scalable solutions.

It is the work of Data Engineers to create tools like the read_csv function so that the rest of the team can concentrate on the data analysis part.

5. Invigorating business

Data engineers are responsible for building the systems that allow data scientists to work on data and provide crucial insights to their senior staff members to make better decisions for the organization. Some industries benefiting from this are healthcare, finance, management, banking, and e-commerce.
