Engineer

An engineer is a person trained in engineering, the application of science and mathematics to design, construct, and improve equipment, buildings, and systems. The work involves solving practical problems while considering cost, safety, time, and available resources.

The term originates from the Latin 'ingenium', meaning ingenuity or mental skill. Initially it was closely associated with the design of military equipment and fortifications, but later extended to all branches of industry and technology.

Branches of engineering

Major branches include civil engineering (buildings, roads, water systems), mechanical engineering (machines and engines), electrical and electronics engineering, chemical engineering, and computer and software engineering. Newer interdisciplinary fields include bioengineering, environmental engineering, and atmospheric engineering.

Training and credentials

Most positions require a university degree in engineering lasting several years, including advanced mathematics, physics, and specialized subjects. Many countries have a certification system allowing only recognized engineers to approve formal designs; titles such as 'Professional Engineer' or 'Chartered Engineer' indicate a level of recognition granted by a professional body.

Daily work and ethics

Engineers use drawings and design software, perform calculations of strength and durability, conduct tests, and assess risk. Professional codes of conduct from engineering bodies typically prioritize public safety over client benefit and require engineers to state the limits of their knowledge and report any errors discovered.

Distinction between engineer and technician

Technicians are typically trained for practical tasks and assembly, following prepared instructions. Engineers are usually responsible for design and technical decisions based on mathematical reasoning. The boundary between the two roles overlaps considerably, particularly in smaller companies.
