Data Science: What is the role of a chief data scientist?

The Chief Data Scientist or CDS for short is a job tile in IT field whose responsibility is to design, develop, deliver and maintain large scale machine learning solutions involving huge data management. The roles and responsibility of Chief data scientists varies according to the organization needs but the goal of delivering large scale machine learning solution remains the same. Depending on the organization it may or may involve actual coding, testing and delivery. If it's small organization then chief data scientist design, code, test and deliver the solution along with the help of small team. If the organization is big and there big team in that case chief data scientist mainly involve in designing of the system and the managerial role.

In this article we are going to explore the core responsibility of a chief data scientist. Even if you are working in big organization and not involved in actual hands-on, you must have prior hands-on in all the technologies used in data science. Because chief data scientist is big role in industry and there is huge investment in any data science project; hence you will be responsible for all the outcome of the project. You have to manage the team and work in such a manner that the product is delivered by team at its maximum capacity.

The chief data scientist is the final decision maker on the algorithms and methodology to use for the delivery of a project. You should have solid understanding of all the algorithms, methodology, data ingestion, data storing, data processing logic and visualization technologies used in data science projects. Having prior experience in Big Data and programming technologies are must to become highly productive chief data scientist.

The chief data scientist role involves understanding the client business requirement, convert into a mathematical problem, solve the mathematical problem with programming/machine learning and finally present the result in dashboard format to client. So, this role requires interaction with client and stakeholders. The software project management and team management skills are a must for this role.

You must have experience in designing; coding, testing and production deliver of various machine learning models. These skills are required because if model is not performing as expected then you can work with your team to tune the model to get best results.

In a small organization you have to hands-on while in big organization such as global banks role changes to 95% admin-related work. In big organization you have to lead a team of reporters, forecasters, data scientists and data modelers. In big organization team management, project management and client handling skills is required along with data science skills. Here you may have to work with team or yourself do the hands-on to create POC for the client fast.

In bigger organizations roles includes the administrative tasks such as insuring data integrity and compliance. You should make sure that the data science processes followed for the projects are robust and really useful for the business. You will be handling a big team and reporting to higher management. Here you will be working as VP of engineering team or we can say VP of data science.

Job description for chief data scientists
