What is Data Engineering and Who Is a Data Engineer?
Data engineering is a highly variable, big-tent field with a primary focus on developing reliable mechanisms or infrastructure for data collection.
Who is a data engineer? A data engineer essentially is anyone who serves as a gatekeeper and facilitator for the movement and storage of data. Data engineers are also often tasked with transforming big data into a useful form for analysis. In order to do this, they design, construct, install, test, and maintain highly scalable data management systems — basically, software needed to store and use this data.
Steps to Become a Data Engineer
Professional opportunities within data engineering are many. From major Silicon Valley tech companies to small startups to healthcare systems, the data engineer helps businesses scale and make the most of their data resources.
But you have to be aware of what it takes to get your foot in the door as a data engineer and stay relevant in the field.
Data engineer veteran, David Bianco, has made a successful career of building geospatial data pipelines. Bianco urges prospective data engineers to become fluent in programming languages and tools that can help them get hired, and understand what those tools can help them accomplish.
“Languages come and go, so it’s better to gain a full understanding of the concepts behind building a robust pipeline,” he says.
Consider Bianco’s advice and these key steps if you want to build a career as a data engineer:
1. Earn a bachelor’s degree and begin working on projects
Anyone who enters this field will need a bachelor’s degree in computer science, software or computer engineering, applied math, physics, statistics, or a related field. You’ll also need real-world experience, like internships, to even qualify for most entry-level positions. For those who choose college majors outside of these fields, ensure you take courses on data structures, algorithms, database management, or coding. It’s important that you learn as much as you can.
Join a study group, attend a hackathon with friends, or take on personal projects with classmates and build a portfolio you can eventually show potential employers.

The online BSc Data Science and Business Analytics from the University of London, with academic direction from LSE, enables students to build essential technical and critical thinking skills and prepare for careers in data science, analytics and other growing fields – while they work, without relocating.
2. Fine tune your analysis, computer engineering and big data skills
You’ll need to hone your expertise in SQL, one of the foundational programming languages data engineers speak. This is necessary because most data is stored in relational database systems. Engineers use SQL to query data and SQL engines, such as Apache Hive, to then analyze this data.
Data engineers should also have an understanding of other programming languages that help with statistical analysis and modeling, such as Python or R. A mastery of Spark, Hadoop, and Kafka will come in handy, too.
Beyond a mastery of language, other skills may include using database architectures, understanding machine learning, finding data warehousing solutions, knowing how to construct data pipelines, data mining, and utilizing cloud platforms like Amazon Web Services.
Data management technology is constantly evolving so it is also important for data engineers to have their hand on the pulse of what’s happening in their field.
3. Get your first entry-level engineering job
Your first job may or may not involve engineering, but even if it is IT-related, you may gain invaluable insights on how to approach data organization challenges. That first job will challenge you to think creatively and find unusual ways to solve problems. Why is this important? You’ll quickly learn that data engineers don’t do it all by themselves. Instead, they listen to management, data scientists and data architects — it’s a collaborative field. During this experience, you may also gain an understanding of the way your chosen industry functions in the real world and how data can be collected, analyzed and utilized.
4. Consider pursuing additional professional engineering or big data certifications
To advance a career in data engineering, it is often necessary to pursue certifications. If you hope to boost specific skills, you’ll find a lot of vendor-specific certifications such as Oracle, Microsoft, IBM, and Cloudera, among others. With so many options available, be sure to speak with mentors to determine which certification is worth your time and money and study the descriptions of jobs you have your eye on to see what certifications might be required. One certification you can obtain is the Certified Data Management Professional or CDMP. Developed by the Data Management Association International (DAMA), the CDMP is a solid, all-round credential for general database professionals. Many employers will recognize the acronym on your résumé.
5. Pursue higher education degrees in computer science, engineering, applied mathematics, physics, or a related field
Many engineers succeed without higher education, but you may also want to consider a master’s degree in computer engineering or computer science degree to fine tune your skills, expand your knowledge, or start working as a data engineer or a data scientist.
Not all jobs require a master’s in data engineering. Some employers are willing to accept relevant work experience and proof of technical expertise in lieu of a higher degree.
Data Engineer Responsibilities
Data engineering is a strategic job with many responsibilities spanning from construction of high-performance algorithms, predictive models, and proof of concepts, to developing data set processes needed for data modeling and mining.
Here is an overview of data engineer responsibilities:
- Ensuring that data storage and collection systems meet business requirements and acceptable industry standards.
- Integrating new data management software into a company’s existing structures or research new opportunities for a business’ data acquisition. This could mean helping a company come up with a new way to efficiently bring in data from a brand-new client.
- Creating custom software components using a wide range of languages and tools — like scripting languages — to merge different systems together or develop a strong analytics infrastructure for measuring your data stored by a business.
- Storing and processing data securely at all times. Data engineers remain on the frontlines of a company’s cyber defenses, installing and updating disaster recovery protocols, in addition to recommending ways to improve data reliability and quality.
Becoming a data engineer can be an opportunity to collaborate with an interdisciplinary group of people, working closely with data architects, modelers, and IT specialists to achieve different project goals.
Data Engineer vs Data Scientist
While a data engineer is responsible for building, testing, and maintaining big data architectures, the data scientist is responsible for organizing big data within the architecture and performing in-depth analyses of the data to help develop insights and solve business needs.
These two professionals often work closely together. A data scientist can’t interpret anything unless there is a data engineer to build the tools for storing and processing that data.
Data Engineer Jobs
The data engineering field is one that is constantly evolving, which can make a data engineer’s life more complicated. But it also presents more job opportunities.
You can work as a data engineer, a senior cloud data engineer, a senior data engineer, and a big data engineer, among other roles.
Basically, it’s an exciting time to be a data “builder.” If you love playing with new tools and can think outside the relational database box, you’ll be in a prime position to help companies adapt to the demands of this industry.
