What are the Qualifications for a Senior Data Scientist?

A senior data scientist is a very specific type of data scientist. They typically have at least five years of experience in a technology-related field, and are proficient in SQL. A senior data scientist is also likely to be familiar with big data and machine learning.

The qualifications for becoming a senior data scientist vary depending on the company, but most organisations require candidates to have at least a bachelor’s degree in computer science or mathematics, along with several years of experience working with SQL. In addition, many senior data scientists are also required to pass a certification exam such as the SAS Institute’s MASTER DATA SCIENTIST certification.

What Do Senior Data Scientists Do?

The senior data scientist is a key member of the data team and oversees data science projects. They work with database administrators, business analysts, developers, and other members of the data team to identify and solve problems in data processing. Senior data scientists typically have a strong understanding of big-data technologies and modeling techniques. They also have experience working with SQL databases and are able to communicate effectively with stakeholders in business operations.
