12 Data Science Roles Worth Pursuing [2022 Career Guide]

In this article

Data science is a field that encompasses several different disciplines and if you’re interested in pursuing a career in data science, you should consider which roles best match your interests and strengths. For example, someone with a strong mathematical base might be best suited to work as a statistician, while a business-focused data science professional would be more fit for a business analyst role. 

We’re going to take a look at the various roles within the larger data science industry, and give you the information you’ll need to help make your own path. 

What Does a Data Scientist Do?

Before we learn about the particulars of different roles within the data science industry, let’s examine their commonalities. Broadly speaking, data science is the process of solving problems or answering questions by gathering and processing datasets. The goal is to take unstructured data and extract meaning from it. 

Businesses hire data scientists to identify the problems and solve them by sourcing and analyzing large volumes of data. Professionals in this space have strong analytical skills in the technical knowledge required to mine, clean, process, and present data.
