An engineer usually has a bachelor's degree in engineering. Engineers initiate design work as part of developing new components, equipment or systems and create new products from a set of specifications. Technicians usually have one to two years of formal education, usually concluding with an Associate's degree. Technician's install, operate and repair the items designed by the engineer. Many technician-level jobs actually have engineering titles even though they involve troubleshooting and repair work instead of design.
Some typical titles are customer engineer and field service engineer.
In terms of education, engineers have a need for a stronger math and science background. Technicians require a practical knowledge of equipment functioning and application.
