What Does a Principal Data Scientist Do?

Before learning about the principal data scientist salary, you must understand the roles and responsibilities of the position.

There are different data scientist levels in an organization- junior, mid-level, senior, principal data scientist, and director. The Principal Data Scientist is a senior position with leadership responsibilities in addition to primary roles that include analyzing data sets to extract relevant insights. The exact duties vary based on the company you are working with. Here is an overview of the role of a principal data scientist in top tech companies:

  • You must direct and develop multiple projects simultaneously.
  • You may not do everything yourself, but you must supervise and guide the data science work from the beginning to the completion of a project. So, you have to handle data acquisition through model development to deployment. 
  • In a dynamic environment, you must master the skill to leverage data science methods, including AI and machine learning.
  • You should possess a proven ability with statistical methods and advanced modeling techniques. For example- SVM, Random Forest, graph models, Bayesian inference, NLP, Computer Vision, neural networks, and more.
  • You have to delegate tasks and manage junior and senior data scientists, data engineers, and program managers. 
  • Principal data scientists integrate with the inter-product level, unlike any other senior data scientist who provides an independent contribution at the intra-product level.
  • You must employ various tools and technologies while creating algorithms and predictive models for large data interpretation for the company's business.
  • If you are a Principal data scientist, you must have the ability to solve data science problems that senior-level data scientists do not. 

Therefore, you must be an expert in specific data science areas, and if not, you must possess the ability to gain the necessary skills quickly.
