Test engineers are responsible for designing and executing tests to verify the integrity, reliability, and quality of products before they are presented to the public. These engineers must have a vast range of technical and problem-solving skills, and must be able to work in teams involving design and development engineers, technicians, craftspeople, as well as management.

The design engineer is accountable for providing the thorough specifications of the products people use, and what most people are thinking of when they think of engineering.
