Who is a Data Engineer?
Data engineers are the Jedi Knights of the data science world. They possess a unique blend of analytical skills, wisdom, experience, and judgment, which they wield to make critical decisions that drive a company’s success. Data engineers are self-starters who excel at taking on a multitude of tasks.
What Does a Data Engineer Do?
Data engineers play a crucial role in the data science pipeline. They take the work done by data architects as a starting point and then preprocess the available data, ensuring it is clean, organized, and ready for analysis. They also implement complex, large-scale big data projects, focusing on collecting, managing, analyzing, and visualizing vast datasets.
Data engineers are responsible for turning overwhelming raw data into actionable insights, utilizing various toolsets, techniques, and cloud-based platforms. They build and maintain ETL pipelines that make crucial data accessible to the entire company. Additionally, they support BI analysts by designing and maintaining BI platforms, ensuring all big data applications are available and performing properly.
How Much Do Data Engineers Earn?
According to Glassdoor and PayScale, data engineers are well-compensated for their expertise. In the United States, entry-level data engineers can expect an average salary of $103,000. As their experience grows, data engineers with 4-6 years of experience can earn around $117,000, with additional bonuses of approximately $10,000. In the UK, data engineers with less than one year of experience can earn an average salary of £30,000, which includes bonuses and overtime pay. With 5-9 years of experience, the annual pay can reach £54,000.
How to Become a Data Engineer
If you are passionate about data science and want to pursue a career as a data engineer, here are the steps you need to take:
1. Acquire the Right Education
While a degree in software engineering, computer science, or information technology provides a strong foundation, it is not mandatory. Many data engineers have transitioned into the field from other disciplines. Regardless of your educational background, gaining knowledge in computer programming, software design, statistical modeling, regression analysis, Python, SQL, and machine learning is essential. Qualification programs and online data science training courses can help you acquire the necessary skills, even if you are a beginner.
2. Develop Technical and Practical Skills
To excel as a data engineer, you need to master a range of technical skills. Knowledge of data modeling for data warehousing and Big Data, along with experience in the Big Data space (Hadoop Stack like M/R, HDFS, Pig, Hive, etc.), is crucial. Proficiency in writing, analyzing, and debugging SQL queries is highly valued by employers. Additionally, gaining experience with scripting languages like Python is essential. Mathematics is also an indispensable skill in the competitive world of data science.
In addition to technical skills, data engineers need to hone their practical and soft skills. Strong data visualization skills, analytical skills, decision-making abilities, attention to detail, critical thinking, and conceptualization are vital. Effective communication skills, both written and verbal, are also essential for collaborating with diverse teams and conveying insights effectively.
