  • Creating data access methods according to business hierarchy,
  • Making the analysis of the existing system, eliminating the deficiencies, providing a transition to new systems when necessary.

3. Business Analyst

Business Analyst is one of the prominent Data Science roles. A business analyst evaluates an institution's business processes, analyzes requirements, finds areas for improvement, and develops solutions. It identifies a project's or program's requirements and communicates them to management and partners. Its goal is to come up with technical solutions to business challenges or to help the company's sales efforts succeed.

The following are the tasks of the business analyst, who shows the connection between business and information technology:

  • Analyzing company functions to set operational goals and acquire knowledge
  • Developing flowcharts and diagrams
  • Examining existing applications to develop systems and design modifications
  • Putting together a project team and a budget
  • Knowledge of advances in information technology to automate and modernize systems.

  • Making meetings and presentations to share ideas and analysis, etc.

To work as a business analyst, you should have a bachelor's degree in computer science, mathematics, industrial and business engineering, management information systems, or statistics.

4. Developer Advocate

Developer Advocacy is the data science role that explains the technology produced by a company to the relevant people. Let’s expand on these concepts a little more;

  • To introduce the technologies that the company they work for is the developer or supporter of
  • Preparing Articles/Blogs about these technologies
  • Providing consultancy by identifying Common Uses for the technologies it is responsible for promoting
  • Assisting the people or institutions that decide on the transition process to the technologies they are responsible for in the implementation process
  • Answering questions and problems in the online platform about the technologies
  • To increase the awareness of the product by making presentations and promotions at events and organizations about the technologies it is responsible for.
  • Constantly following current and trending technologies and learning new technologies

5. Data Analyst

Data analyst is one of the most popular data science roles. With the advancement of technology, companies have begun to build their own databases. On their own, these numbers don’t make sense. You may remain ahead of your competition by transforming data into information in the direction you wish. The data analyst job role is to transform this data into information when you ask for it. Data becomes meaningful when it is processed to solve a problem or serve a specific purpose. The data analyst’s most fundamental task is to make the raw data meaningful.

The main tasks of data analysts needed in many sectors are as follows:

  • To determine the analysis and measurement methods of the data,
  • To make the data obtained from the measurements made more understandable,
  • Researching the financial records of companies,
  • Doing business with simple and useful solutions,
  • To provide communication between corporate companies,
  • Identifying business needs
  • To produce solutions to meet the goals and objectives.

6. Machine Learning Engineer

Data Science is an interdisciplinary process. A Data Scientist role is to extract knowledge and insights from structured and unstructured data. Data Science relates to machine learning, data mining, and big data. — Wikipedia

According to Wikipedia, we can say that Machine learning is a branch of data science, as machine learning models learn from data.

In other words, machine learning engineers can make data meaningful with programming.

For machine learning engineers, the first and foremost requirement might be, which is well equipped on a programming language. Python is the most common language of “Machine Learning”. In the future, you probably need to learn all these languages like C++, R, Python, Java and work on MapReduce.

Here is the source about languages:

Python vs R: which language is better for a data science career?

There are many machine learning techniques. A solid understanding of algorithm theory and knowledge of topics such as Gradients, Convex Optimizations, Quadratic Programming, and Partial Differentiation will be very helpful. Keep calm and start with Python!

  • Preparing user manuals and design documents, conveying the necessary instructions to the users.

8. Research Scientist & Research Engineer

There is no difference between a research scientist and a research engineer for some companies. First and last, research scientists should be engineers. Engineers and research scientists both come up with and develop strategies. A researcher may also serve as a consultant, advising research engineers on their own projects.

A research engineer’s job role is to utilize their technical talents to set up and execute experiments for these concepts, much as a research scientist’s job is to come up with unique ideas. A Ph.D. and/or first author papers at top-tier conferences are generally required for the research scientist position.

As a research engineer/scientist, you usually know to:

  • Learning and using new ways to find answers, such as building mathematical models that interpret data in a meaningful way,
  • Presents results to top management and at group and department meetings,
  • During the course of a project, meets with partners to address ideas and outcomes.
  • Clients are given instructions on how to accomplish it, to reap the benefits of mathematical analysis, and to offer recommendations based on these analyses
  • Being able to manage a research team (or manage a group of research students in academic settings),
  • Proposing new ways to analyze data as well as generating tailored solutions to business problems using innovative and existing methods,
  • Sharing the results of new research by writing original articles for publication in peer-reviewed scientific journals, as well as preparing regular reports on the progress of the study

Final Thoughts

Your ability to quickly master the essential skills required to evaluate big data sets, as well as your dedication to the company with which you are working, will determine your progress. Junior data scientists may be promoted to higher-level data science roles within your organization, including line management. It might take two to five years to advance from junior to senior data scientist.

Being in a data science role, you’ll be expected to take on greater people management responsibilities after five years. It may be quite easy to move to different companies because the skills you learn are transferable across different industries. Joining a startup and working on projects outsourced by larger companies is another option. The things that will advance you in your data science career path are faith, patience, and hard work.
