This question is about what an engineer does.
The engineering hierarchy consists of principal and distinguished engineers at the top, with staff and senior engineers at the lower half of the hierarchy.
The hierarchy of engineers also depends on the organization the engineers work for, the engineering work being done, and other factors. In general, though, most companies structure the engineering hierarchy in this manner, starting with the lowest role and ascending towards the highest:
Staff engineer
Senior staff engineer
Principal engineer
Distinguished engineer
Depending on the scale of the organization, principal engineers can have a hierarchy dedicated specifically to them. Here is a common principal engineering hierarchy, from lowest role to highest role:
Principal engineer
Senior principal engineer
Distinguished principal engineer
Fellow engineer
Here is a quick look at some of these specific engineering roles in the engineering hierarchy:
Staff engineer
A staff engineer reports directly to the directors of engineering. Staff engineers design, build, and test structures, products, systems, services, or equipment depending on their specialty.
They are employed in various industries and mainly specialize in civil, mechanical, industrial, or electrical engineering. Staff engineers, such as staff software engineers, may also work in the technology space.
Senior Engineer
Senior engineers are professionals who receive this title through experience. They may handle several projects simultaneously, performing engineers' tasks and providing team guidance.
These engineers are highly technical and ensure teams apply common engineering principles and concepts to their own teams' responsibilities.
Principal Engineer
A principal engineer is a professional who oversees other engineers in different departments and contributes to multiple projects at one time. A principal engineer has many years of experience and training in particular or multiple engineering fields.
They oversee and manage engineers in a specific department or several different departments. Leadership is a crucial component of a principal engineer's job.
Some of their responsibilities include planning engineering strategies for a company, managing several departments and figuring out goals for each, and writing and managing engineering budgets.
