Data engineering is the fastest-growing tech occupation. That’s according to DICE’s 2020 Tech Jobs Report. In 2019, data engineering saw 50% year-on-year growth, 12% more than back end development and 18% more than data science. The conclusion here is obvious. If you’re looking to future-proof your career, data engineering is the field to be in.
Data engineering is the backbone of data science. Data engineers design, build, maintain, and test data management systems. These systems are vital for transforming data into formats data scientists and data analysts can use to create practical conclusions (and visualizations). As such, data engineers are just as important as data scientists, even though the latter make news headlines more often.
As Paul Lappas, the co-founder and CEO of Intermix, a performance monitoring solution, said in a Stitch interview, “It’s an unsexy job, but it’s super-critical. Data engineers are kind of like the unsung heroes of the data world. Their job is incredibly complex, involving new skills and new tech.”
What skills are we talking about? Programming languages like Python and SQL (R may come in handy, too) as well as tools and platforms like AWS, Apache Hadoop, Apache Hive, and Scala, says that same DICE report. Finding individuals with such a specialized skill set is no easy feat, which is why it takes 46 days on average to fill a data engineer position. Naturally, when a company does manage to hire a data engineer, they pay them well. According to Glassdoor, the average data engineer makes $102,864 (as of the time of writing this article).
Interested in going down the data engineer route but don’t know where to start? Below is a list of the seven best data engineering courses right now — all of which are available online.
