Data science job outlook
The future is bright for aspiring data science professionals. In 2020, IBM predicted that there would be 2.7 million open jobs across data science and related careers and that there would be a 39 percent growth in employer demand for data scientists and data engineers.
For data scientists specifically, the US Bureau of Labor Statistics estimates the employment growth rate to grow by 22 percent by 2030. It is considered the third-best job in the US (as of March 2022), according to Glassdoor.
There are plenty of data science jobs to choose from. All of them are integral to making key business decisions. Often, several of the job types below will work together on the same team.
Data scientists build models using programming languages such as Python. They then transform these models into applications. Often working as part of a team, for example, with a business analyst, a data engineer, and a data (or IT) architect, they help solve complex problems by analyzing data and making predictions about the future. This role is typically considered an advanced version of a data analyst.
Average US Salary: $99,138
Skills needed: Statistics, mathematics, machine, deep learning, programming skills, data analysis, big data processes, and tools like Hadoop, SQL, and more.
Education: Bachelor’s degree in a related field, although increasingly data science boot camps, master’s programs, and professional certificates can help career switchers reach their goals. According to a Burtch Works study of data scientists and salaries, more than 94 percent of data scientists held a master’s or doctorate degree.
Data analysts, unlike data scientists, use structured data to solve business problems. Using tools such as SQL, Python, and R, statistical analysis, and data visualization, data analysts acquire, clean, and reorganize data for analysis to spot trends that can be turned into business insights. They tend to bridge the gap between data scientists and business analysts.
Average US Salary: $63,344
Skills needed: Programming languages (SQL, Python, R, SAS), statistics and math, data visualization
Education: Bachelor’s degree in mathematics, computer science, finance, statistics, or a related field
Data architects create the blueprints for data management systems, designing plans to integrate and maintain all types of data sources. They oversee the underlying processes and infrastructure. Their main goal is to enable employees to gain access to information when they need it.
Average US Salary: $115,196
Skills needed: Coding languages such as Python and Java, data mining and management, machine learning, SQL, and data modeling
Education: A bachelor’s degree in data, computer science, or a related field. If you are switching careers, a Bootcamp or professional certificate can help develop your skills in data management.
Data engineers prepare and manage large amounts of data. They also develop and optimize data pipelines and infrastructure, getting the data ready for data scientists and business analysts to work with. Data Engineers make the data accessible so businesses can optimize their performance.
Average US Salary: $97,727

Machine learning engineer
This role is not an entry-level position, but one you can build toward as a data scientist or engineer. Machine learning uses algorithms that replicate how humans learn and act, to interpret data and build accuracy over time. As part of a data science team, machine learning engineers research, build, and design artificial intelligence that facilitates machine learning. They also serve as a liaison between data scientists, data architects, and more.
Average US Salary: $100,066
