The roles of machine learning engineer and data scientist are similar, considering that both positions need certain defined qualifications, work on similar technologies, and handle huge data sets. The article tries to cover the differences between machine learning engineers and data scientists.
Did you know that over 2.5 Quintillion bytes of data are generated daily across the globe! IDC predicts that by 2025, there will be 175 zettabytes of data, marking a growth of 61%. To manage such humongous volumes of data and get desirable conclusions, organizations need experts. Machine learning engineers and data scientists are two of the most trendy job profiles in the world of data right now. Often there is confusion around the roles of these two. In this article, we discuss machine learning engineer vs data scientist, their job roles, and difference in skills and eligibility.

Who is a Data Scientist?
Data scientists are the professionals responsible to manage and find trends in messy, unstructured data. Such data may come from a range of sources like social media, online news, huge datasets, emails, mobile devices, to name a few. Data scientists have an impeccable command over mathematics, statistics, computer science, data analysis, and programming.
Their expertise is now required in almost all sorts of industries with the aim of obtaining reliable solutions to everyday problems. For example, determine user behavior, predict sales of a product, forecast performance of campaigns, among others.
Who is a Machine Learning Engineer?
A machine learning engineer is responsible for creating programs and algorithms that enable machines to perform specific tasks. These programs and algorithms allow machines to perform actions without being specifically told to do those tasks and improve from their experience. The machine learning engineer needs to have a substantial set of skills in algorithm development and ML design. They should know how these technologies work, how to work with data and be able to contribute to the full life cycle of an ML project.
