Overall job opportunities in engineering are expected to be
good, but to vary by specialty.
A bachelor's degree is required for most entry-level jobs.
Starting salaries are significantly higher than those of college
graduates in other fields.
Continuing education is critical to keep abreast of the latest
technology.
Nature of the Work
Engineers apply the theories and principles of science and
mathematics to research and develop economical solutions to
technical problems. Their work is the link between perceived
social needs and commercial applications. Engineers design products,
machinery to build those products, factories in which those
products are made, and the systems that ensure the quality of
the products and efficiency of the workforce and manufacturing
process. Engineers design, plan, and supervise the construction
of buildings, highways, and transit systems. They develop and
implement improved ways to extract, process, and use raw materials,
such as petroleum and natural gas. They develop new materials
that both improve the performance of products and take advantage
of advances in technology. They harness the power of the sun,
the Earth, atoms, and electricity for use in supplying the Nation's
power needs, and create millions of products using power. They
analyze the impact of the products they develop or the systems
they design on the environment and people using them. Engineering
knowledge is applied to improving many things, including the
quality of health care, the safety of food products, and the
efficient operation of financial systems.
Engineers consider many factors when developing a new product.
For example, in developing an industrial robot, engineers determine
precisely what function the robot needs to perform; design and
test the robot's components; fit the components together in
an integrated plan; and evaluate the design's overall effectiveness,
cost, reliability, and safety. This process applies to many
different products, such as chemicals, computers, gas turbines,
helicopters, and toys.
In addition to design and development, many engineers work
in testing, production, or maintenance. These engineers supervise
production in factories, determine the causes of breakdowns,
and test manufactured products to maintain quality. They also
estimate the time and cost to complete projects. Some move into
engineering management or into sales. In sales, an engineering
background enables them to discuss technical aspects and assist
in product planning, installation, and use. (See the statements
on engineering and natural sciences managers and sales engineers
elsewhere in the Handbook.)
Most engineers specialize. More than 25 major specialties are
recognized by professional societies, and the major branches
have numerous subdivisions. Some examples include structural,
environmental, and transportation engineering, which are subdivisions
of civil engineering; and ceramic, metallurgical, and polymer
engineering, which are subdivisions of materials engineering.
Engineers also may specialize in one industry, such as motor
vehicles, or in one field of technology, such as turbines or
semiconductor materials.
This statement, which contains an overall discussion of engineering,
is followed by separate statements on 14 engineering branches:
aerospace; agricultural; biomedical; chemical; civil; computer
hardware; electrical and electronics, except computer; environmental;
industrial, including health and safety; materials; mechanical;
mining and geological, including mining safety; nuclear; and
petroleum engineering. (Computer software engineers are discussed
elsewhere in the Handbook.) Some branches of engineering not
covered in detail in the Handbook, but for which there are established
college programs, include architectural engineering-the design
of a building's internal support structure; and marine engineering-the
design and installation of ship machinery and propulsion systems.
Engineers in each branch have a base of knowledge and training
that can be applied in many fields. Electronics engineers, for
example, work in the medical, computer, communications, and
missile guidance fields. Because there are many separate problems
to solve in a large engineering project, engineers in one field
often work closely with specialists in other scientific, engineering,
and business occupations.
Engineers use computers to produce and analyze designs; to
simulate and test how a machine, structure, or system operates;
and to generate specifications for parts. New communications
technologies using computers are changing the way engineers
work on designs. Engineers can collaborate on designs with other
engineers around the country or even abroad, using the Internet
or related communications systems. Many engineers also use computers
to monitor product quality and control process efficiency. They
spend a great deal of time writing reports and consulting with
other engineers, as complex projects often require an interdisciplinary
team of engineers. Supervisory engineers are responsible for
major components or entire projects.
Working Conditions
Most engineers work in office buildings, laboratories, or industrial
plants. Others may spend time outdoors at construction sites,
mines, and oil and gas exploration and production sites, where
they monitor or direct operations or solve onsite problems.
Some engineers travel extensively to plants or worksites.
Many engineers work a standard 40-hour week. At times, deadlines
or design standards may bring extra pressure to a job. When
this happens, engineers may work longer hours and experience
considerable stress.

Almost half of all wage and salary engineering jobs were found
in manufacturing industries, such as transportation equipment,
electrical and electronic equipment, industrial machinery, and
instruments and related products. About 401,000 wage and salary
jobs were in services industries, primarily in engineering and
architectural services, research and testing services, and business
services, where firms designed construction projects or did
other engineering work on a contractual basis. Engineers also
worked in the construction and transportation, communications
and utilities industries.
Federal, State, and local governments employed about 179,000
engineers in 2000. Almost half of these were in the Federal
Government, mainly in the Departments of Defense, Transportation,
Agriculture, Interior, and Energy, and in the National Aeronautics
and Space Administration. Most engineers in State and local
government agencies worked in highway and public works departments.
In 2000, about 43,000 engineers were self-employed, many as
consultants.
Engineers are employed in every State, in small and large cities,
and in rural areas. Some branches of engineering are concentrated
in particular industries and geographic areas, as discussed
later in this chapter.
A bachelor's degree in engineering is required for almost all
entry-level engineering jobs. College graduates with a degree
in a physical science or mathematics occasionally may qualify
for some engineering jobs, especially in specialties in high
demand. Most engineering degrees are granted in electrical,
electronics, mechanical, or civil engineering. However, engineers
trained in one branch may work in related branches. For example,
many aerospace engineers have training in mechanical engineering.
This flexibility allows employers to meet staffing needs in
new technologies and specialties in which engineers are in short
supply. It also allows engineers to shift to fields with better
employment prospects or to those that more closely match their
interests.
Most engineering programs involve a concentration of study
in an engineering specialty, along with courses in both mathematics
and science. Most programs include a design course, sometimes
accompanied by a computer or laboratory class or both.
In addition to the standard engineering degree, many colleges
offer 2- or 4-year degree programs in engineering technology.
These programs, which usually include various hands-on laboratory
classes that focus on current issues, prepare students for practical
design and production work, rather than for jobs which require
more theoretical and scientific knowledge. Graduates of 4-year
technology programs may get jobs similar to those obtained by
graduates with a bachelor's degree in engineering. Engineering
technology graduates, however, are not qualified to register
as professional engineers under the same terms as graduates
with degrees in engineering. Some employers regard technology
program graduates as having skills between those of a technician
and an engineer.
Graduate training is essential for engineering faculty positions
and many research and development programs, but is not required
for the majority of entry-level engineering jobs. Many engineers
obtain graduate degrees in engineering or business administration
to learn new technology and broaden their education. Many high-level
executives in government and industry began their careers as
engineers.
About 330 colleges and universities offer bachelor's degree
programs in engineering that are accredited by the Accreditation
Board for Engineering and Technology (ABET), and about 250 colleges
offer accredited bachelor's degree programs in engineering technology.
ABET accreditation is based on an examination of an engineering
program's student achievement, program improvement, faculty,
curricular content, facilities, and institutional commitment.
Although most institutions offer programs in the major branches
of engineering, only a few offer programs in the smaller specialties.
Also, programs of the same title may vary in content. For example,
some programs emphasize industrial practices, preparing students
for a job in industry, whereas others are more theoretical and
are designed to prepare students for graduate work. Therefore,
students should investigate curricula and check accreditations
carefully before selecting a college.
Admissions requirements for undergraduate engineering schools
include a solid background in mathematics (algebra, geometry,
trigonometry, and calculus) and sciences (biology, chemistry,
and physics), and courses in English, social studies, humanities,
and computers. Bachelor's degree programs in engineering typically
are designed to last 4 years, but many students find that it
takes between 4 and 5 years to complete their studies. In a
typical 4-year college curriculum, the first 2 years are spent
studying mathematics, basic sciences, introductory engineering,
humanities, and social sciences. In the last 2 years, most courses
are in engineering, usually with a concentration in one branch.
For example, the last 2 years of an aerospace program might
include courses in fluid mechanics, heat transfer, applied aerodynamics,
analytical mechanics, flight vehicle design, trajectory dynamics,
and aerospace propulsion systems. Some programs offer a general
engineering curriculum; students then specialize in graduate
school or on the job.
Some engineering schools and 2-year colleges have agreements
whereby the 2-year college provides the initial engineering
education, and the engineering school automatically admits students
for their last 2 years. In addition, a few engineering schools
have arrangements whereby a student spends 3 years in a liberal
arts college studying pre-engineering subjects and 2 years in
an engineering school studying core subjects, and then receives
a bachelor's degree from each school. Some colleges and universities
offer 5-year master's degree programs. Some 5- or even 6-year
cooperative plans combine classroom study and practical work,
permitting students to gain valuable experience and finance
part of their education. All 50 States and the District of Columbia
usually require licensure for engineers who offer their services
directly to the public. Engineers who are licensed are called
Professional Engineers (PE). This licensure generally requires
a degree from an ABET-accredited engineering program, 4 years
of relevant work experience, and successful completion of a
State examination. Recent graduates can start the licensing
process by taking the examination in two stages. The initial
Fundamentals of Engineering (FE) examination can be taken upon
graduation. Engineers who pass this examination commonly are
called Engineers in Training (EIT) or Engineer Interns (EI).
The EIT certification usually is valid for 10 years. After acquiring
suitable work experience, EITs can take the second examination,
the Principles and Practice of Engineering Exam. Several States
have imposed mandatory continuing education requirements for
relicensure. Most States recognize licensure from other States.
Many civil, electrical, mechanical, and chemical engineers are
licensed as PEs.
Engineers should be creative, inquisitive, analytical, and
detail-oriented. They should be able to work as part of a team
and to communicate well, both orally and in writing. Communication
abilities are becoming more important because much of their
work is becoming more diversified, meaning that engineers interact
with specialists in a wide range of fields outside engineering.
Beginning engineering graduates usually work under the supervision
of experienced engineers and, in large companies, also may receive
formal classroom or seminar-type training. As new engineers
gain knowledge and experience, they are assigned more difficult
projects with greater independence to develop designs, solve
problems, and make decisions. Engineers may advance to become
technical specialists or to supervise a staff or team of engineers
and technicians. Some may eventually become engineering managers
or enter other managerial or sales jobs. (See the statements
under management and business and financial operations occupations,
and sales and related occupations elsewhere in the Handbook.)
Job Outlook
Overall engineering employment is expected to increase more
slowly than the average for all occupations. However, overall
job opportunities in engineering are expected to be good through
2010 because the number of engineering degrees granted is not
expected to increase significantly over the 2000-10 period.
Projected employment growth and, thus, job opportunities vary
by specialty, ranging from a decline in employment of mining
and geological engineers to faster-than-average growth among
environmental engineers. Competitive pressures and advancing
technology will force companies to improve and update product
designs and to optimize their manufacturing processes. Employers
will rely on engineers to further increase productivity, as
investment in plant and equipment increases to expand output
of goods and services. New computer and communications systems
have improved the design process, enabling engineers to produce
and analyze various product designs much more rapidly than in
the past and to collaborate on designs with other engineers
throughout the world. Despite these widespread applications,
computer technology is not expected to limit employment opportunities.
Finally, additional engineers will be needed to improve or build
new roads, bridges, water and pollution control systems, and
other public facilities.
Many engineering jobs are related to developing technologies
used in national defense. Because defense expenditures-particularly
expenditures for aircraft, missiles, and other weapons systems-are
not expected to return to previously high levels, job outlook
may not be as favorable for engineers working in defense-related
fields although defense expenditures are expected to increase.
The number of bachelor's degrees awarded in engineering began
declining in 1987 and has continued to stay at about the same
level through much of the 1990s. The total number of graduates
from engineering programs is not expected to increase significantly
over the projection period.
Although only a relatively small proportion of engineers leaves
the profession each year, many job openings will arise from
replacement needs. A greater proportion of replacement openings
is created by engineers who transfer to management, sales, or
other professional occupations than by those who leave the labor
force.
Most industries are less likely to lay off engineers than other
workers. Many engineers work on long-term research and development
projects or in other activities that continue even during economic
slowdowns. In industries such as electronics and aerospace,
however, large cutbacks in defense expenditures and government
research and development funds, as well as the trend toward
contracting out engineering work to engineering services firms,
have resulted in significant layoffs for engineers.
It is important for engineers, like those working in other
technical occupations, to continue their education throughout
their careers because much of their value to their employer
depends on their knowledge of the latest technology. Although
the pace of technological change varies by engineering specialty
and industry, advances in technology have significantly affected
every engineering discipline. Engineers in high-technology areas,
such as advanced electronics or information technology, may
find that technical knowledge can become obsolete rapidly. Even
those who continue their education are vulnerable to layoffs
if the particular technology or product in which they have specialized
becomes obsolete. By keeping current in their field, engineers
are able to deliver the best solutions and greatest value to
their employers. Engineers who have not kept current in their
field may find themselves passed over for promotions or vulnerable
to layoffs, should they occur. On the other hand, it often is
these high-technology areas that offer the greatest challenges,
the most interesting work, and the highest salaries. Therefore,
the choice of engineering specialty and employer involves an
assessment not only of the potential rewards but also of the
risk of technological obsolescence.
