Engineer
An engineer is an individual who has a degree or is highly skilled in a particular field. For example, a hardware engineer is an individual who is very knowledgeable in computer hardware or designs computer hardware components. Another example, a software engineer, who is an individual skilled in computer software, testing, or writes computer software.
Sometimes, a company may have different levels of engineers to help identify their skill level. For example, an individual may have the job title of a Level II hardware engineer or be a distinguished engineer because of their experience.
