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 develop and implement improved ways to
extract, process and use raw materials. They develop new materials that improve
the performance of products and take advantage of advances in technology. 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.
In addition to design and development, many engineers
work in testing, production or maintenance. Some move into engineering management
or into sales.
Most engineers specialize. More than 25 major specialties
are recognized by professional societies, and the major branches have numerous
subdivisions.
Engineers in each branch have a base of knowledge
and training that can be applied in many fields. 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. With new communications
technologies, engineers can collaborate on designs with other engineers around
the country or even abroad, using the Internet or related communications systems.
Many engineers 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.
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. 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.
Training and qualifications
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 may qualify for some engineering jobs, especially
in specialties in high demand. Most engineering degrees are granted in electrical,
electronics, mechanical or civil engineering, but engineers trained in one branch
may work in related branches.
Graduate training is essential for engineering faculty
positions and many research and development programs. Many engineers obtain
graduate degrees in engineering or business administration to learn new technology
and broaden their education. 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 so they can effectively interact with specialists
in a wide range of fields outside engineering.
Job outlook
Overall engineering employment is expected to increase
more slowly than the average for all occupations, but 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 job opportunities vary by specialty.
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
and speeded up the design process, but computer technology is not expected to
limit employment opportunities. The job outlook may not be as favorable for
engineers working in defense-related fields because weapons systems expenditures
are not expected to return to previously high levels.
Engineers who have not kept current in their field
may find themselves passed over for promotions or more vulnerable to layoffs.
On the other hand, it often is the fast-changing, high-technology areas that
offer the greatest challenges, the most interesting work and the highest salaries.
Earnings
In 2000, engineers held 1.5 million jobs. Almost
half of all wage and salary engineering jobs were found in manufacturing industries.
