What is the hierarchy of job titles for scientists?

By Zippia Team - Aug. 8, 2023

The hierarchy of job titles for scientists includes two to three levels of scientist roles followed by senior and principal roles. An entry-level position as a scientist is known as a Scientist I position.

After about one to three years of experience as a Scientist I, you should be promoted to a Scientist II position. Some companies may have a Scientist III position; it depends on the company's size and the industry.

You are eligible for a senior scientist spot after five or more years of experience in a Scientist II position. A senior scientist helps manage Scientists I and II work on the study and works relatively independently of the principal scientist.

The last level of the hierarchy is a principal scientist. The principal scientist is accountable for the entire lab and all of the research it produces. A principal scientist takes the lead in research and development, and everyone, including the senior scientist, must report to the principal scientist.

The hierarchy of scientific job titles often extends beyond the principal scientist role, particularly in larger organizations or those engaged in extensive research and development activities. Following the role of principal scientist, there are further levels of seniority that scientists can aspire to.

The role of a director of science or research director is typically the next step after the principal scientist. This position involves not just overseeing the research but also playing a significant part in determining the strategic direction of the organization's scientific endeavors. A director of science is often responsible for managing multiple principal scientists and ensuring that their collective efforts are aligned with the organization's overall goals.

  • Scientist II

  • Senior Scientist

  • Principal Scientist

  • Director of Science / Research Director

In some organizations, there may be a further level known as vice president (VP) of research or chief scientific officer (CSO). This position is usually part of the executive leadership team and plays a critical role in shaping the company's scientific policies. The VP of research or CSO ensures that all research and development activities support the company's mission, strategic objectives, and growth plans.

  • Scientist I

  • Scientist II

  • Senior Scientist

  • Principal Scientist

  • Director of Science / Research Director

  • Vice President of Research / Chief Scientific Officer

This hierarchy provides a clear progression path for scientists starting at an entry-level position to potentially reach executive management levels. However, it's important to note that climbing this ladder requires not just technical expertise and experience but also a broader understanding of business and strategic planning.
