Machine Learning Engineer vs Data Scientist

Machine Learning Engineer vs Data Scientist
Machine Learning Engineer vs Data Scientist

A machine learning engineer isn’t expected to understand the predictive models and their underlying mathematics the way a data scientist is. A machine learning engineer is, however, expected to master the software tools that make these models usable.

With the rapid development of Artificial Intelligence, there are newer jobs daily coming up in the market. And there is some misunderstanding about the positions of machine learning engineers vs data scientists, mainly since both are comparatively new emerging fields.

When you sort it out and explore the terminology, the details, differences & roles should become apparent.

We are considering professional-level scientists and engineers roles. While a scientist needs to better understand the science and underlying principle behind their research, an engineer’s job is to just build something.

Machine learning engineers and data scientists are two of the trendiest Jobs in the market right now. With 2.5 Quintillion bytes of data being created every day, the expert who can manage this massive data to produce desirable solutions is in total demand.

Competition is rising between machine learning engineers vs data scientists and the gap between them is decreasing.

In this article, we will start by explaining what each of the profiles means and then compare both of them on professional fronts. It will then be followed by a machine learning engineer VS data scientist comparison.

Who is a Data Scientist?

A data scientist is a specialist who gathers, analyzes, and interprets extremely large quantities of data. The position of a data scientist is an extension of many conventional technical positions including a mathematician, scientist, statistician, and qualified computer scientist.

What do they do?

Most companies look out for data scientists for gathering, process, and deriving valuable insights from the data when a company needs to address questions or fix a problem.

When a company hires data scientists they will start exploring all areas of the business and devise strategies using programming languages such as Java to conduct robust analysis.

Along with many other techniques, they will use digital experimentation to help companies grow and prosper.

In addition, they can create customized data solutions to make businesses better understand themselves and their customers to make critical business decisions.

Who is a Machine Learning Engineer?

Machine learning engineers upload data into models generated by data scientists. They are also responsible for carrying theoretical models of data science and helping to extend them to production-level applications that can accommodate terabytes of real-time data.

What do they do?

Machine learning engineers are working at a crossroads between software engineering and data science. They harness big data tools and programming frameworks to reinvent the raw data obtained from data pipelines as data science models are prepared to expand as required.

Machine learning engineers often create systems that control machines and robots. The algorithms built by machine learning professionals allow a computer to recognize trends in its programming data and educate itself to comprehend instructions and even think for itself.

Machine Learning Engineer VS Data Scientist

A data scientist’s position these days have become much more generalized and broad-based to the degree that it could fully supersede Machine Learning. And yet, there are cases where a data scientist does not perform data analysis on the data itself.

A data scientist’s role can be multifarious. Manipulating, processing, and querying large volumes of concurrent data is now an incredibly skilled task in the age of ‘Big Data technologies. Thus, a data scientist’s main function may be, for example, to run and manage an architecture to absorb a wide range of data from various sources.

Statistics differ greatly in terms of wages and future growth! But one thing is for certain the number of positions for data scientists well outruns the number of jobs for engineers in machine learning.

And it can be said confidently that these jobs will certainly not go anywhere, at least for the next 20 years, as the amount of data and its complexities will continue to increase significantly more.

Have a look at the following machine learning vs data scientist comparison.

A lot of Data Scientists’ job postings appeared and were flooding the market in the previous years. The same for the Machine Learning Engineer position is happening, it’s a fairly new one and is slowly evolving in areas where we have data specialists.

Now, if we compare Machine Learning Engineer vs Data Scientist, we need to consider a couple of parameters:

  1. Salary
  2. Skills
  3. Programming languages
  4. Experience

These are some of the factors that will tell you a lot about both fields, namely machine learning and data science.
