O’Reilly Media released the results of its second-annual data science salary survey on Thursday (available for free download here), and the results were not too surprising. Essentially, it shows that people who work with tools designed for big data, machine learning, statistical computing and cloud computing make more money — often between $20,000 and $30,000 more a year, based on median incomes — than people whose jobs only involve tools such as SQL and Excel.
In that regard, the survey doesn’t really tell us anything new. All the talk over the past couple years about competitive recruitment and high salaries for data scientists was true, and it was true precisely because companies want the people who know how to work with new technologies. They want this decade’s data scientists — people who can build AI systems or pipelines for streaming sensor data — not last decade’s data analysts.
The survey has all sorts of interesting findings about how much people earn based on tools or combinations of tools they use, but two charts probably sum it up the best. The first shows the gap in median incomes between people who use Hadoop and people who do not.
The second shows how use of bigger, faster and sometimes more advanced tools such as HBase, Storm and Spark increases median salaries even more.
It’s a good thing companies are still hiring.
