What are the job opportunities / roles available in the area of Big Data?
The roles are very fluid. Just a few year ago everything was about capturing, storing and processing data. Now this is largely a solved problem, and these functions will be automated and outsourced to generalized products. The growth is in data analysis and machine learning. I expect a rise of domain specific roles, like “marketing data scientist,” “UI/UX data scientist,” “sales data scientist,” etc.
