It's common for engineers to work in offices, although some may work in labs or visit sites as part of their work. They typically work on many different engineering projects at the same time, so they need to be able to multitask. Senior engineers have more experience and authority than staff engineers have. While senior engineers are known for their technical expertise and the application of engineering theories, principal engineers are associated with pioneering development within their field and may prove theories or develop new theories. Principal engineers are experts, and their success has a direct bearing on the image of their lab, so they can impact their company's profile and reputation.
One of the distinctions is that principal engineers report to senior management, while senior engineers report to the leadership of their division.
