Aerospace engineers perform and supervise the design, development, manufacture and maintenance work of all types of flight vehicles. This may include military and civilian aeroplanes, helicopters, missiles, launch vehicles, spacecraft, satellites, and control and guidance systems.

Agricultural engineers study and advise on the use of engineering science and technology in agricultural production and management of natural resources. They solve problems relating to such things as sustainable agricultural production, the environmental impacts of intensive agriculture and the post-harvest handling of agricultural products.

Aircraft maintenance engineers install, maintain and repair aircraft engines; airframes; airframe systems; electrical, instrument and radio systems; and aircraft structures and surface finishes.

Biomedical engineers apply engineering and scientific methods to find solutions to problems in medicine and the life sciences.

Chemical engineers design and coordinate the construction and operation of manufacturing facilities and processes that convert raw materials into everyday products such as petrol, toothpaste, pharmaceuticals and plastics.

Civil and structural engineering associates provide technical support to civil engineers and civil engineering technologists. They assist with the research, design, construction, operation and maintenance of projects such as roads, airports, railways, buildings, bridges, dams and drainage systems.

Civil engineers plan, design, construct, operate and maintain roads, bridges, dams, water supply schemes, sewerage systems, transportation systems, harbours, canals, dockyards, airports, railways, factories and large buildings.

Civil engineering technicians conduct tests of construction materials and prepare sketches and tables for civil engineers and civil engineering technologists. They assist with the research, design, construction, operation and maintenance of projects such as roads, airports, railways, buildings, bridges, dams and drainage systems.

Civil engineering technologists assist civil engineers in the research, design, construction and maintenance of civil engineering projects. Typical projects include dwellings, large buildings, railways, roads, bridges, airports, ports and docks, dams and water supply systems.

Computer engineers are involved in the installation, repair and servicing of computers and associated equipment.

Electrical engineers design, develop and supervise the manufacture, installation, operation and maintenance of electrical systems. They work on systems for the generation, distribution, utilisation and control of electric power. They also work on electronic systems used for computing, communications and other industrial applications.Electrical engineers may specialise as electrical maintenance engineers, electrical power engineers, electrical design engineers, communications engineers or computer engineers. They may also specialise in areas such as the design and operation of power plants, generators, metal refining, rolling mills, motors and transformers, and in researching new applications of technology or production machinery.

Electrical engineering associates are involved in the planning, design, selection, installation, starting up and maintenance of electrical equipment, facilities, power plant installations, parts and distribution systems. Electrical engineering associates usually work on a range of duties that lie between the trade level and technologist level. Electrical engineering associates may specialise as electrical engineering design drafters, technical officers, substation design officers, test officers and power-system controllers.

Electrical or electronics engineering technologists apply engineering principles to the design, manufacture, installation, commissioning, operation and maintenance of electrical and/or electronic plants and equipment.

Electronics engineers design, develop, test and maintain electronic parts and systems used in computers, communications, navigation, industry and entertainment.

Electronics engineering associates conduct and assist with the research, design, manufacture, repair and maintenance of advanced electronic equipment and systems. Electronics engineering associates usually have a range of duties that lie between trade and professional engineer levels.
