Engineers - What do engineers do? (2023)

Engineers apply scientific and mathematical principles to develop economical solutions to technical problems. Their work is the link between scientific discoveries and commercial applications that meet the needs of society and consumers.

Many engineers develop new products. During the process, they consider several factors. When developing an industrial robot, for example, engineers precisely define the functional requirements; design and testing of robotic components; integrating the components to create the final design; and evaluate the overall effectiveness, cost, reliability, and safety of the design. This process is used in the development of many different products such as chemicals, computers, power plants, helicopters and toys.

In addition to their involvement in design and development, many engineers work in test, production, or maintenance. These engineers oversee production in the factories, determine the causes of component failures, and test manufactured products to maintain quality. They also value the time and expense it takes to complete projects. Senior engineers are responsible for large components or entire projects.

Engineers use computers extensively to create and analyze designs; to simulate and test how a machine, structure or system works; generate specifications for parts; product quality monitoring; and control the efficiency of the processes. Nanotechnology, in which high-performance materials and components are created through the integration of atoms and molecules, also introduces entirely new principles into the design process.

Most engineers specialize. The following are details of the 17 engineering occupations included in the federal government's Standard Occupational Classification System (SOC). Numerous other specialties are recognized by professional organizations, and each of the major engineering branches has numerous sub-divisions.

Petroleum engineers design methods for extracting oil and gas from underground reservoirs. Once these resources are discovered, petroleum engineers work with geologists and other specialists to understand the geological formation and properties of the rocks containing the reservoir, determine drilling methods to be used, and oversee drilling operations and production. They design equipment and processes to achieve the maximum profitable extraction of oil and gas. Because only a small portion of the oil and gas in a reservoir flows through natural forces, petroleum engineers develop and use various improved extraction methods, including injecting water, chemicals, gases, or steam into an oil reservoir to force out more oil and gas. computer controlled drilling or fracturing to connect a larger area of ​​a reservoir with a single well. Because even the best techniques used today produce only a fraction of the oil and gas in a reservoir, petroleum engineers research and develop technologies and methods to increase the recovery of these resources and reduce the costs of oil and gas exploration, drilling and production.

Most engineers work in office buildings, laboratories or industrial plants. Others may spend time outdoors at construction sites and oil and gas exploration and production sites to oversee or direct operations or troubleshoot on-site issues. Some engineers travel a lot to factories or construction sites at home and abroad. Many engineers work a standard 40-hour week. Sometimes deadlines or design standards can add stress to a job, requiring engineers to put in more hours.

Almost all engineering jobs require an engineering degree. Graduates with a degree in science or mathematics may occasionally qualify for some engineering careers, particularly in high-demand disciplines. Most engineering degrees are awarded in electrical, mechanical and civil engineering. However, engineers trained in one industry may work in related industries. For example, many aerospace engineers have a background in mechanical engineering. This flexibility allows employers to meet staffing needs in new technologies and specialties where engineers are in short supply. It also allows engineers to move into fields with better career prospects or into those closest to their interests.

Most engineering programs involve a concentration of study in an engineering degree, along with courses in both math and science and life sciences. Many programs also include general engineering degrees. A design course, sometimes accompanied by a computer or laboratory course, or both, is part of the curriculum of most programs. General education courses without direct engineering reference, for example in the social sciences or humanities, are often required.

In addition to the standard engineering degree, many universities offer 2- or 4-year engineering technology majors. These programs, which typically include various hands-on laboratory courses that focus on current problems in the application of engineering principles, prepare students for hands-on design and production work rather than jobs that require more theoretical and scientific knowledge. Graduates of 4-year technology programs can obtain similar jobs as graduates with a bachelor's degree in engineering. However, engineering graduates are not eligible to register as professional engineers on the same terms as graduates with engineering degrees. Some employers consider graduates of technology programs to have skills somewhere between those of a technician and an engineer.

A college education is essential for engineering school positions and some research and development programs, but not a requirement for most entry-level engineering jobs. Many experienced engineers earn an engineering or business degree to learn about new technologies and learn more. Many senior leaders in government and industry began their careers as engineers.

The Accreditation Board for Engineering and Technology (ABET) accredits college and university programs in engineering and engineering technology. ABET accreditation is based on a program's faculty, curriculum, and facilities. Coursework in a program; program improvements; and institutional commitment to specific quality and ethical principles. Engineers who require a license may require completion of an ABET-accredited program.

Although most institutions offer programs in the major branches of engineering, few offer programs in the smaller specialties. Also, shows with the same title may vary in content. For example, some programs emphasize industrial internships that prepare students for a position in industry, while others are more theoretical and are designed to prepare students for graduate work. Therefore, students should research study plans and carefully consider accreditations before choosing a university.

Admission requirements for undergraduate engineering schools include a solid background in mathematics (algebra, geometry, trigonometry, and calculus) and science (biology, chemistry, and physics), as well as courses in English, social studies, and humanities. Engineering majors are typically 4 year long, but many students find it takes 4-5 years to complete their degree. In a typical 4-year college curriculum, the first 2 years are spent studying mathematics, fundamental sciences, elementary engineering, liberal arts and social sciences. In the final 2 years, most majors are engineering, usually with a concentration in one subject. Some programs offer a general engineering curriculum; The students then study part-time or in graduate school.

Some engineering schools have agreements with 2-year colleges whereby the college offers an initial engineering education and the engineering school automatically admits students for the last 2 years. In addition, some engineering schools have agreements that allow students who spend 3 years at a liberal arts college with pre-engineering majors and 2 years at an engineering school with core subjects to receive a bachelor's degree from either school. Some colleges and universities offer 5-year master's programs. Some 5 or even 6 year collaboration plans combine classroom learning with hands-on work, allowing students to gain valuable experience and fund part of their education.

All 50 states and the District of Columbia require a license for engineers offering their services directly to the public. Licensed engineers are called Professional Engineers (PEs). This license typically requires completion of an ABET-accredited engineering program, 4 years of relevant work experience, and completion of a state exam. New graduates can begin the licensing process by taking the two-tier exam. After completing the course, the first examination Fundamentals of Engineering (FE) can be taken. Engineers who pass this exam are commonly referred to as Engineers in Training (EIT) or Engineers in Training (EI). After gaining relevant work experience, EITs can take the second exam, known as the Principles and Practice of Engineering exam. Several states have mandated continuing education requirements for license renewal. Most states will recognize licenses from other states so long as the manner in which the original license was obtained meets or exceeds their own licensing requirements. Many civil, mechanical, and chemical engineers are licensed PEs. Regardless of license, professional organizations offer various certification programs to demonstrate competency in specific areas of engineering.

Engineering employment is expected to grow at the average rate for all occupations over the next decade, but growth will vary by specialty. Biomedical engineers should see the fastest growth, while civil engineers should see the largest job growth. In general, good career opportunities are expected in engineering.

Earnings for engineers vary significantly by specialty, industry, and education. The differences in median earnings and earnings distributions for engineers in different disciplines are particularly significant. The average annual salary for engineers in the private sector is $122,100. In the federal government, the average annual salary for engineers ranged from $101,085 in agricultural engineering to $146,788 in ceramics engineering. As a group, engineers earn some of the highest average starting salaries among those with a bachelor's degree.
