Data Science Jobs Roles and Responsibilities


In an industry where new jobs are continually being created, data science has shifted from a buzzword into a strategic component of the business world. Also, data scientists are playing an increasingly strategic role as companies use a product-centric view of data. This area promises tremendous employment growth and higher earnings potential. There is significant job growth in this sector. Data analysis experts are currently benefiting from the wave of big data.

This exponential growth of the sector has given rise to a new trend: jobs are becoming more formal, admission requirements are strict, and new titles are emerging. For example, we see Business Analyst and Business Intelligence Analyst jobs that do not seem so far apart, but professionals have a different career path and revenue potential.

With the increase in jobs, new job titles go hand in hand. Some of these responsibilities may overlap, but there are also apparent differences. Today, Data Science offers non-MINT majors that do not have the programming context to enter the market.

7 Fastest Growing Job Roles In Data Science

1) Data Scientist

Role: As the world’s most prominent post-millennium job, the demand for data scientists is widespread, from large corporations to start-ups and majors of e-commerce. The market gradually evolves to become a computer specialist in its own right, working on a specific application such as NLP or Computer Vision and developing data-oriented products at the forefront of the market. With the growing need for talent in space, more data mining courses, programming, analysis, etc. are proposed.

Essential Skills: Experience with machine learning algorithms/algorithms in predictive modeling and analysis; Analysis techniques such as regression, classification, clustering, and time series are preferred for Data Scientist roles. Lately, Python has proven to be the most researched skill by scientists.

3) Data engineer

Role: Data engineers have become a central part of the data science teams and one of the most challenging positions to fill. It seems that companies are struggling to find data engineers with the right experience and expertise. Data Engineers are responsible for building data pipelines and supporting pilot case use cases in the production phase.

Essential Skills: Data engineers have experience with Hadoop-based technologies such as MapReduce, Hive, MongoDB, or Cassandra. You also have in-depth knowledge of data warehousing and NoSQL technologies. Big Data technologies should master general programming languages ​​and higher programming languages, such as Python, R, SQL, and Scala.

3) Business Analyst / Data Analyst / BI Analyst

Role: Business Analyst understands business and data needs, translates operational needs of customers, has extensive domain expertise, and can also collect data and generate reports. The critical competencies required are the combination of analytical and operational capabilities to move projects forward and a deep understanding of how business analytics can add value to businesses.

The main difference between Business Analyst and Data Analyst is that DAs work with large amounts of data has a quantitative basis, programming, and analytics experience, while BAs work more commercially, collecting and analyzing data, including scope and project requirements, making effective decisions. Both roles require different skills.

Meanwhile, a BI analyst works primarily on reports, creates and implements reports and dashboards, and makes recommendations based on results. BI analysts have excellent dashboard skills and are proficient in SQL and Tableau. However, if you are geared towards compensation and want to plan a new career, a course will allow you to develop essential skills for all roles that use a lot of data.
