How data engineers tame Big Data?
Machine learning engineer vs data scientist
While the terms “data scientist” and “machine learning engineer” are often used interchangeably, they are two distinct job roles with unique responsibilities. At a high level, the distinction between scientists and engineers is apparent, as they have different areas of expertise and skill sets. While both roles involve working with large datasets and require proficiency in complex data modeling, their job functions differ beyond this point.
Data scientists typically produce insights and recommendations in the form of reports or charts, whereas machine learning engineers focus on developing software that can automate predictive machine learning models. The ML engineer’s role is a subset of the data scientist’s role, acting as a liaison between model-building tasks and the development of production-ready machine learning platforms, systems, and services.
One of the significant differences between data scientists and ML engineers lies in the questions they ask to solve a business problem. A data scientist will ask, “What is the best machine learning algorithm to solve this problem?” and will test various hypotheses to find the answer. In contrast, an ML engineer will ask, “What is the best system to solve this problem?” and will find a solution by building an automated process to speed up the testing of hypotheses.
Both data scientists and machine learning engineers play critical roles in the lifecycle of a big data project, working collaboratively to complement each other’s expertise and ensure the delivery of quick and effective business value.
