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,

  • 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.
