Are you also excited about a career in data science that not just rewards handsomely but also offers excellent growth prospects? Then, being a data scientist is the role you must aim for.
Data science is one of the fastest-growing industries in terms of both organizational adoption and employment opportunities. According to the WEF 2025 Global Outlook, data science jobs are among the fastest-growing jobs, with roles like Big Data Specialists and machine learning specialists growing at approximately 113% and 85% respectively over the next 5 years.
Data science is the field dedicated to extracting meaningful and actionable insights from various kinds of structured and unstructured data, and data scientists are the core professionals handling the entire operation, of course with the help of other data professionals.
In this guide, we will explore the most detailed roadmap to a career as a data scientist and learn what they do, what skills they require, what is data scientist salary, and how you can become one for a successful data science career.
Who is a data scientist, and what do they do?
These are expert data science professionals having a deep knowledge of mathematics and statistics, computer science, and programming languages, and their industry or domain knowledge. They gather, analyze, and visualize data to identify trends and patterns that can be used to make informed decisions.
The average salary of data scientists in the US is $127641 per annum (Source: Indeed). So, we can imagine how rewarding this career path is.
The following are the key roles and responsibilities of a data scientist:
- Data collection and preprocessing: They collect data from various sources and refine it for analysis
- Use data science tools: They use different kinds of data science tools to clean, process, and analyze data
- Data visualization: They also translate complex insights into easy-to-understand visuals for non-technical stakeholders for better understanding
- Exploratory data analysis: Data scientists perform data analysis to identify trends and patterns and extract insights from data.
- Model development and deployment: They help build data science models like predictive models or recommendation systems and deploy them in the production environment.
Skills Required to Become a Data Scientist
So, if you want to become a skilled and successful data scientist, you mandatorily need to master the core data science skills and knowledge and work efficiently in your data science career.
The following are some of the must-have technical and non-technical skills for data scientists:
· Programming languages – learn different programming languages such as Python, R, SQL, Java, essential for data science workflows.
· Data manipulation and Analysis – familiarize yourself with popular data manipulation and analysis libraries such as Pandas, NumPy, and others.
· Machine learning – basic understanding of various machine learning algorithms, techniques, and libraries (Scikit-learn), PyTorch, TensorFlow, etc, is required.
· Data visualization – data scientists also need to know about data visualization tools like matplotlib, Seaborn, TensorFlow, or PyTorch to build predictive models.
· Big data tools – learn and get some experience with big data tools like Hadoop, Spark, AWS, etc., to manage huge datasets
· Statistics and mathematics – knowledge of mathematics and statistics is required for building algorithms, data analysis, and modeling.
Apart from these technical skills, it is advised to sharpen soft skills like
- Problem-solving
- Communication
- Business acumen
- Collaboration with professionals from other teams and departments
Mastering all these skills will open doors for exciting career opportunities in the field of data science, including the role of senior data scientist as well.
