In-Demand Job Profiles in Big Data and Analytics Industry

August 28, 2017 0 comments

The Big Data and Analytics field is constantly evolving and constantly making way for new technologies to be picked up and mastered for companies and professionals to stay ahead in the competition. As this field is further broken down in terms of skill requirements, there are many interdependent roles that emerge and the definitions of these roles are also dynamically evolving.

In this data-driven era, not just the top players in every industry but also most of the small and mid-size businesses (SMBs) are spending their bucks on hiring different Big Data and Analytics related talents. Job portals globally have seen a significant hike in Big Data related postings in the past few years.

So, whether you are a fresher or someone who is now looking for a change in your career path, the basic understanding of different profiles can better guide you as to in which domain lies your interest and expertise.

‘Big Data’ is a rather abstract term with several diverse positions under its umbrella. The profiles can be broadly classified into categories:

  • Big Data Engineers
  • Big Data Analysts

Although stated distinctly, there are many skills that are common to both. In simple words, if you are a mathematician or statistician with a liking for programming and analysis then the latter can be your prospects and if you are proficient in programming skills, databases, etc. then it could be the former. To go by an interesting definition given by Josh Wills, Director of Data Engineering at Slack, a data scientist/engineer (in general) is a person who is better at statistics than any software engineer and better at software engineering than any statistician.

Here are six careers paths under Big Data and Analytics. Let’s take a closer look at what each position stands for and the tools used in each:

Database Manager: It is a Database management role wherein they oversee the development and use of data systems. Essentially an IT role, it may be required for database managers to perform some data analysis.
