Job Roles Big Data – Roles and Responsibilities in Big data jobs

Big data drove an estimated approximately $200 billion in IT spending in 2015. The main reason for this growth is the potential Chief Information Officers (CIOs) see in the greater insights and intelligence contained in the huge unstructured data.

Analysis of unstructured data requires new systems of record—for example, NoSQL databases which can forecast better and align their strategic plans and initiatives for an organization.

Big Data job opportunities attract many experienced and talented software engineers who are technically proficient and most importantly are passionate about what they do. Here are some of the job opportunities in Big Data space:

Here are some of the job opportunities in Big Data space.
