Who is a Data Scientist?
Data scientists are professionals who possess numerous skills. These professionals are a combination of statisticians, trend-spotters, mathematicians, and computer scientists. The main job role of these professionals is to decipher and decrypt large chunks of data and further analyze them to explore and extract patterns to gain valuable insights. Data scientists operate in the world of IT, business, and several other industries by analyzing complex sets of data to gain insights that can be leveraged into actions by organizations.
Data scientists generally collect and analyze business data. They do this with the help of a myriad of tools, technologies, and techniques with one goal in mind, reaching a sensible conclusion with the help of the given data. Usually, they present their organizations’ data in a visual format so that the other members of the organizations can visualize the data in a comprehensive format.
What Do They Do?
Let us briefly understand what these professionals do and what is demanded by a data science career. We will also take a look at their various roles and responsibilities.
The main role of a data scientist in an organization is to perform data mining, and data cleaning, and further represent the data with data visualization tools to the members of the organization such that they can read and comprehend the presented data. Organizations look for these professionals so that they can help store, manage, and analyze large amounts of raw organizational data, which is provided in both structured and unstructured format.
Data Science Career Path
Data science is now a term known and used across various industries. Hence, organizations expect data scientists to have a much more comprehensive skill set and a broader understanding of various business processes. So, choosing the right career path involves acquiring the right skills, knowing the job requirements, and exploring the correct career opportunities.
Typically, the career trajectory of a data scientist involves working across various roles such as data analyst, data engineer, business intelligence developer, and data scientist. These are considered to be the main phases or steps in the career path of a data scientist.
We will now cover the basic corporate ladder and skill set of each of these roles:
Skill Set: A data analyst is skilled in data modeling, data cleaning, visualization or business intelligence, and R and/or Python programming. A data analyst also having knowledge in tools such as Tableau is highly recommended.
Corporate Ladder: As an entrant, a professional start their career as a data analyst. After gaining two to four years of experience, they go on to become an associate data analyst and later move on to becoming a senior analyst and finally a product manager with approximately nine to ten years of experience.
Skill Set: A data engineer is skilled in database management, data mining, programming, business acumen, visualization, and more.
Corporate Ladder: A data engineer starts from the junior level and goes on to become the product manager in a span of ten to twelve years, based on the skill development over these years.
Business Intelligence Developer
Skill Set: The core skill set of a business intelligence developer includes programming, visualization, data modeling, business acumen, etc.
Corporate Ladder: A business intelligence developer starts their career as a junior business intelligence developer and reaches the level of a team lead in a span of twelve to fifteen years, depending on the skill development and experience gained over the years.
Skill Set: The core skill set of a data scientist includes statistics, mathematics, programming, business acumen, and problem-solving.
Corporate Ladder: A data science aspirant can start their career as a junior data scientist or any of the above-mentioned roles such as data analyst, business intelligence developer, etc. After gaining the required skill set, they can make a transition to the data scientist profile. However, one point that needs to be considered is that organizations might rename some positions as data scientists. Hence, the role and responsibilities should be considered carefully when it comes to the profile of a data scientist.
