8 Data Science Positions to Consider – 2023 Career Guide


If you’re interested in a career in data science, you should consider which roles best match your interests and talents because this area crosses many other fields. For instance, a person with a strong background in mathematics may be most suited to work as a statistician, whereas a data science expert with a business orientation may be better suited for a business analyst position.


We’ll examine the many positions within the broader data science sector and provide you with the knowledge you’ll need to help forge your own career path.


What Do Data Scientists Really Do?


Before learning about their specifics, let’s look at the similarities between various professions within the data science business. Data science, in its broadest sense, is acquiring and analyzing datasets to solve issues or provide answers. The objective is to derive meaning from unstructured data.


Companies employ data scientists to locate issues and find solutions by collecting and analyzing vast amounts of data. Specialists in this field possess the technical expertise needed to mine, clean, process, and present data, as well as strong analytical skills with the best data analytics course and get the IBM certificate.


What are the Different Data Science Positions?

  • Data Engineer:


Data engineers prepare unformatted data for analysis. They gather data needed later, maintain it, and transform it so that business analysts and other team members may use it. Data engineers create systems that make massive amounts of data more accessible to an organization.




  • Based on organizational goals, gather data and produce datasets.
  • Designing the infrastructure for data pipelines to data warehouses and databases 
  • Converting raw data into useable information
  • Verify that data governance policies are followed


Most data engineers hold a bachelor’s degree in mathematics or computing. They must know SQL database technology and programming languages like Python and Scala. In this job, platforms like Apache Spark and Hadoop are frequently employed.

  • Machine Learning Engineer:


Machine learning engineers use artificial intelligence to automate data analysis procedures. This covers procedures like pattern recognition, data mining, and predictive modeling. Engineering, math, and artificial intelligence all come together in this position.




  • Create machine learning algorithms to automate tasks involving data.
  • Statistical data analysis and machine learning algorithm optimization.
  • To streamline productivity, select machine learning libraries and tools.
  • Find datasets to use for new machine learning models’ training.


For positions as a machine learning engineer, a bachelor’s degree in computer sciences or engineering is necessary. Experts in this discipline must know statistics and machine learning techniques. Engineers specializing in machine learning must also be familiar with database design and systems. Check out the data scientist course fees at the Learnbay website.

  • Machine Learning Scientist:


Machine learning experts occupy roles that emphasize research. They investigate the models and techniques a business intends to use in its data analysis workflow. Machine learning scientists evaluate algorithms’ effectiveness, applicability, and security, whereas machine learning engineers mostly implement them.




  • Determine potential algorithms to address various data-related business issues.
  • Examine several algorithms and note important features.
  • Analytical algorithms are tested and put into use.
  • Inform diverse stakeholders about their findings.


With a focus on artificial intelligence and neural networks, machine learning specialists frequently hold doctoral degrees. In order to model machine learning algorithms, they employ programs like OpenCV. Working knowledge of distributed systems and model deployment are prerequisites for the position.

  • Business intelligence Developer:


Data is analyzed by a business intelligence developer, who then produces insights for the company. In order to aid in company decision-making, business intelligence engineers also produce reports with comprehensible insights.




  • Convert organizational requirements into technical requirements for data teams.
  • To find data points for datasets and analyze markets, products, and interactions between products and markets.
  • Create mechanisms for tracking business performance and produce reports for senior teams.
  • QA tests should be performed on business intelligence systems.

  • Business Analyst:


Business analysts use data to analyze shifting business requirements and assess the impact of shifting business processes. Also, they work as liaisons between various teams, facilitating the conversion of company objectives into specific targets.




  • Data is used to simulate business processes and assess the effects of different modifications.
  • Translate requirements and communicate modifications to various parties
  • Analyze proposed data analysis changes and make recommendations.


Strong analytical capabilities are required of business analysts. They do analyses that call for data wrangling and data manipulation using Python, and R. Business analysts frequently utilize software like Power BI and Tableau to create reports.

  • Database manager:


A database administrator (DBA) is responsible for managing a company’s database, which is crucial because a business needs constant, dependable access to accurate data. DBAs design processes for backing up data and ensuring databases operate properly.




  • Database systems should be watched for any performance or security issues.
  • Create permissions for various stakeholders and prevent unwanted access.
  • Create the database architecture and front end so other team members can access it easily.
  • Make that database functionality complies with the organization’s data governance requirements.


For database administrators, having a solid grasp of database technologies like SQL, PostgreSQL, and Oracle is essential. A career in the sector may benefit from earning a certification like the Microsoft Certified Database Administrator (MCDBA). DBAs must keep up with changes in their industry and suggest new tools or procedures.

  • Statisticians:


To analyze numerical data, statisticians employ analytical procedures. They aid in developing scale models and algorithms used in calculations and projections by other data experts.




  • Speak with several departments to get numbers
  • Make computations and forecasts with statistical methods.
  • Provide management with their statistics findings
  • Assist professionals in constructing models to extract insights from numerical data including data scientists.


Professional statisticians with experience in data science typically hold a bachelor’s degree or higher in the subject. You must possess good quantitative and analytical abilities to work in the field. A popular language for statistical analysis is SPSS. R and Python are also tools used by statisticians.

  • Application Architect:


Application architects create computer programs that aid in data interpretation. Instead of concentrating on data, application architects do so. During the development process, experts in this discipline evaluate business needs and solicit input from diverse stakeholders.




  • By working with managers, identify company needs and issues that can be solved with data.
  • Create prototypes based on input from various stakeholders.
  • Create programs and do tests
  • Do migrations, upgrades, and maintenance while integrating the application with current systems.


Programming languages, including C,.NET and Java, are well-versed by application architects. Also, they are knowledgeable in SQL and other database systems. An extensive background working in development teams is necessary to become an applications architect and also get clarified with the data science course fees offered.




Without a degree, some organizations employ data scientists. If you don’t have the necessary degree, you must show that you possess math and calculation abilities. Bootcamp or course completion can demonstrate this. Candidates who have completed personal projects excite recruiters.
