18. Earnings:
According to the U.S. Department of Labor,
Bureau of Labor Statistics, the median income
for computer engineers is $97,400. The lowest
10% earned $59,170. The highest 10%
earned $148,590.
According to a July 2009 survey by the
National Association of Colleges and
Employers, the average starting salary for
computer engineers who have earned a
Bachelor's degree is $61,738.

19. Employment:
According to the U.S. Bureau of Labor
Statistics, computer engineers hold about
74,700 jobs in the United States.
Computer engineers are employed in industry,
government, education and consulting. They
may be working on a new design of an
electronic component for an individual project,
focused on the development of software
specific to a new product, or one being
redesigned, or may work in sales or in
supporting research activitis.

Computer Engineering
20. Employment (continued):
Computer engineers frequently work on new
applications of computers, such as advances
in digital television and photography, virtual
meeting technology, intelligent highways,
control systems, and new technologies for
cars, phones, security systems, telescopes,
airplanes, and space vehicles.
A sample list of employers of Computer
Engineers is available at the
Sloan Career Cornerstone Center.

21. Career Path Forecast:
According to the U.S. Department of Labor,
Bureau of Labor Statistics, computer hardware
engineers are expected to have employment
growth of 4 percent over the projections
decade, slower than the average for all
occupations.
Although the use of information technology
continues to expand rapidly, the manufacture
of computer hardware is expected to be
adversely affected by intense foreign
competition.

Computer Engineering
22. Career Path Forecast (continued):
As computer and semiconductor
manufacturers contract out more of their
engineering needs to both domestic and
foreign design firms, much of the growth in
employment of hardware engineers is
expected to take place in the computer
systems design and related services industry.
