Predictive, prescriptive, and descriptive analysis are used to translate data into meaningful insights.

Depending on these insights, business analysts recommend modifications and strategic decisions to reduce expenses while improving internal and external reporting. People serving such data science roles find gaps in their current procedures and use accessible data to grow the firm.  This necessitates assessing the potential consequences of various options and adopting new mechanisms.  Business Analysts are required to have a solid grasp of the business, as well as technical abilities such as data modeling and visualization tools such as Tableau.

6. Statistician

Individuals with these data science jobs are responsible for extracting relevant insights from data. They have a solid foundation in statistical theories, techniques, and data organization, and they work with a wide range of data to generate information. They collect, organize, present, analyze, and evaluate data in order to draw reliable findings and make sound judgements. To become a statistician, one must have both statistical and domain knowledge.

These professionals use statistical analysis tools to analyze data, detect patterns and trends and then explain the results using data visualization tools or reports. They manage databases and statistical programs, assure data accuracy, and develop new programmes, models, and tools. Statisticians should be highly skilled in MATLAB, R, SQL, SAS, Python, Pig and Hive. Apart from these technologies, they should be knowledgeable in statistical theory, cloud computing, machine learning, data mining, database management systems, distributed computing tools and data visualization.

7. Machine Learning Engineer

These data science jobs are in high demand today is the role of a machine learning engineer. To address business difficulties, Machine Learning Engineers must be knowledgeable and proficient in a variety of machine learning methods like classification, clustering, prediction, and anomaly detection. Strong statistics and programming abilities are essential for becoming an ML Engineer. In addition to creating and constructing machine learning systems, machine learning engineers must conduct A/B testing, create data pipelines, and monitor the performance and functioning of the various systems.

Machine Learning Engineers require in-depth knowledge of languages like Java, Python, SQL, C++, and Scala. They work with other teams to enhance data quality and monitor performance to guarantee that machine learning systems are dependable. They should be experienced in designing highly scalable and distributed systems because they work with large datasets. They require a solid mathematical and statistical foundation. This function is substantially more technical than the other Data Science roles.

8. Database Administrator

Database administrators do one of the most crucial data science jobs. They are responsible for managing an organization’s databases. They are responsible for constant database monitoring to guarantee correct operation, data security, control of user access and permissions to databases, and data availability by performing frequent backups and retrieving data as needed. They work on database software to store, organize, and manage data, as well as aid with database design and development.
