Applied Scientist vs. Data Science Engineer

Applied Scientist vs Data Science Engineer: A Comprehensive Comparison

Table of contents

The fields of Artificial Intelligence (AI), Machine Learning (ML), and Big Data have been gaining popularity in recent years. As a result, there has been a surge in demand for professionals with specialized skills in these areas. Two such roles that are often confused with each other are Applied Scientist and Data Science Engineer. This article aims to provide a detailed comparison between these two roles, including their definitions, responsibilities, required skills, educational backgrounds, tools and software used, common industries, outlooks, and practical tips for getting started in these careers.

Definitions

An Applied Scientist is a professional who applies scientific principles to solve real-world problems. They use their expertise in Mathematics, Statistics, Computer Science, and domain-specific knowledge to create models, algorithms, and systems that can be used to solve complex problems. They work on a wide range of projects, including product development, Research, and innovation.

A Data Science Engineer, on the other hand, is a professional who builds and maintains the infrastructure required to support data-driven applications. They design, develop, and deploy Data pipelines, databases, and other systems that enable the processing and analysis of large datasets. They work closely with data scientists to ensure that the data is organized, cleaned, and stored in a way that is easily accessible and usable.
