Engineering is an occupation with an extremely wide reach. The term ‘engineering’ covers many fields and, by extension, many skills. Engineers are scientists, inventors, designers, builders, and great thinkers. They improve the state of the world, amplify human capability and make people’s lives safer and easier.

Engineering skills include:

  • the scientific method
  • social, cultural, and economic awareness
  • mathematics
  • biology, chemistry, physics, and other areas of science
  • creativity
  • teamwork

Engineering disciplines cover:

  • Mechanics and the construction of tools and machines of all sizes, from the nanoscale to entire manufacturing facilities.
  • The creation of cars, trains, ships, boats, aircraft, and all other vehicles.
  • The design and production of chemical compounds.
  • Operations of businesses and cities.
  • Entertainment, industry, construction, transport, healthcare, defense, and more!

One of the great attractions of engineering work is the huge variety of tasks and environments in which engineers find themselves working.

From designing programs at a computer terminal to overseeing maintenance operations for major structures like aircraft, ships, heavy earth-moving equipment, mobile cranes, and offshore oil platforms – there are many ways to be an engineer.

A great deal of engineering work is carried out with the aid of computers. This can range from design to testing, the control of systems, the direction of equipment, and the analysis of the properties of materials.

Engineering Disciplines: The main disciplines

Historically, mainstream engineering was divided into the four broad disciplines of chemical, civil, electrical, and mechanical engineering, with several branches within each discipline covering an enormous range of fields.

Aerospace Engineering

Aerospace Engineers design, construct and operate aircraft, aerospace vehicles, and propulsion systems. This includes planes, jets, helicopters, gliders, missiles, and spacecraft. They are involved in researching, developing, and testing new materials, engines, body shapes, and structures that may increase the speed and strength of aircraft.

Aerospace Engineers are also responsible for planning thorough maintenance programs for aircraft and exercising strict safety and environmental controls. Aerospace Engineers also use their knowledge of electrical, electronic, and computer systems for automatic control and communication systems for the operation of aircraft.

Aeronautical Engineering deals specifically with flight vehicles such as airplanes and helicopters. Work in this field is still available, however, it is being overtaken by aerospace engineering.

Aerospace Engineers may be responsible for investigating faulty engines or other components, and for developing repair systems. They may be involved in designing improved air conditioning or fuel systems for aircraft or ground-based systems for operations such as flight control. They may prepare technical or commercial information when competing with other companies for the manufacture or supply of equipment.

The aerospace industry in Australia is changing from having an introspective defense-dependent focus to a more export-oriented outlook. Opportunities now exist for research and development into composite material and manufacturing techniques, exploring how products are made. Many aircraft components are now made from advanced composite materials, such as carbon fiber-reinforced plastics.

There are three main areas of work in the aerospace industry; design and manufacture, research and development, and airworthiness operations.

A new graduate engineer may be involved with one aspect of a project such as calculating the type and weight of material to go into a component.

Senior engineers may be in charge of coordinating a whole project, giving other engineers, technicians, and draftspersons different tasks to complete, and ensuring that the project meets the budget.

The Civil Aviation Safety Authority employs Aeronautical Engineers whose main task is to ensure that Australian aircraft are airworthy. This covers the certification of aircraft and involves the assessment of manufacturers’ data from within Australia and overseas.

They may have to assess mechanical systems, flight characteristics, and aircraft performance. This may be done by test flights, measuring take-off distances, rate of climb, stall speeds, maneuverability, and landing capacities, and comparing results with safety standards.

Aerospace Engineers may also work for commercial airline companies, aerospace manufacturers, government defense departments, defense forces, and government research laboratories.

The Australian aerospace industry is very small, however many graduates find their advanced technological skills are transferable to work in related fields. One such example is the automotive industry which occasionally advertises for aerospace engineers.

Engineering Disciplines: Agricultural Engineering

These engineers are involved in conserving and developing the world’s natural resources including soil, water, land, rivers, and forests. They research and develop solutions to combat problems such as soil erosion and salinity. They are responsible for designing better methods of farming and forestry, improving farming machinery and buildings, and also for lessening the impact of humans on the environment.

Agricultural Engineers may work towards solutions for problems such as sustainable agricultural production, and the environmental impact of intensive agriculture and also look at the ways in which agricultural and primary products are handled.

Many Agricultural Engineers are employed by government departments in such areas as water supply, agriculture, forestry, soil conservation, and environmental protection agencies.

Private employers may include consulting firms, manufacturers and distributors of agricultural and irrigation equipment, corporate farms, intensive animal industries, and food processing plants. Work may also be available on overseas agricultural aid programs.

Biomedical Engineers use microcomputers, lasers, and other materials to develop and improve medical research equipment that is used to diagnose health problems. They may be involved in the development of medical products and different types of equipment used to monitor and treat patients and in designing and improving equipment for disabled people.

A Biomedical Engineer working in a hospital, for example, may be responsible for the safe and effective operation of equipment such as monitoring, diagnostic, and therapeutic medical equipment ranging from catheters, CAT scanners, pacemakers, and kidney machines.

Biomedical Engineers may be involved in designing artificial joints and limbs and assisting the surgical team in fitting these to the patient. They design and deliver technology to improve the quality of life of people with disabilities. For example, they may develop equipment to assist people who have difficulty walking, communicating, or carrying out simple daily tasks.

Building Services

Building Services Engineers are involved with designing heating, air-conditioning, electric lighting and power, water and gas supply, plumbing, and drainage systems. Fire safety and security systems, phones, faxes, intercoms, computers, lifts, and escalators are all needed for a functional and safe work environment.

Chemical Engineering

Chemical Engineering is concerned with the ways in which raw materials are changed into useful and commercial end products. Research of raw materials and their properties, design, and development of equipment, and the evaluation of operating processes are all part of Chemical Engineering.

The above skills are combined to extract raw materials which can then be refined and manufactured to produce such things as food, petrol, plastics, paints, paper, ceramics, minerals, and metals. Often these processes are carried out at large-scale plants and the safe operation of these plants is also part of chemical engineering.

Extracting these raw materials without harming the environment is also a major area of work for Chemical Engineers. For example, new types of fuels which can be used safely to provide the energy we need, without having an adverse effect on the environment, are currently being developed and tested. Chemical engineers are also involved in the production of pharmaceutical products as diverse as penicillin and shampoo.

Chemical Engineers may work in companies involved in the production of such things as food, plastics, ceramics, pharmaceuticals, metals, and glass.

Many Chemical Engineers also find employment in environment protection and the reclamation or clean-up of contaminated sites, or in research laboratories, chemical plants, and petroleum refineries. Other major employers of chemical engineers include manufacturers of basic iron and steel products, organic industrial chemicals, and the mining industry.

Engineers working in this field may specialize as combustion engineers, petroleum engineers, principal chemical engineers, smelting engineers, water treatment engineers, or environmental engineers (see the section on environmental engineering). There is also scope for Chemical Engineers to move into related areas including biotechnology, food engineering, and mineral engineering.

Food Engineering

Food Engineers design equipment, machinery, and production methods that increase the life of food whilst maintaining its quality and nutritional value. They also ensure that the food produced is free from bacteria and disease and does not lose its original texture and color.

Petroleum & Petrochemical Engineering

Engineers in this field find, produce, use, and improve oil and natural gas based on geological studies. Methods of removing oil and gas from the earth safely and economically are constantly being researched and tested. Raw materials extracted from the earth or oceans are turned into synthetic fibers, dyes, detergents, and many forms of plastic materials and products.


Equipment that produces life-saving drugs and medicine is designed and operated by engineers in the pharmaceutical field. These drugs need to be made very precisely in both small and large quantities. Engineering teams work closely with medical research teams to achieve the most effective results.

Process Control

Process Control Engineers are concerned with creating and maintaining computer software and systems designed to control the quantity and quality of a particular product when it is being manufactured. Computers are used in a chemical plant to control such things as pressure, temperature, and liquid levels in a tank.

It is also important to ensure that the minimum amount of waste material is produced during manufacturing.


Production Engineers are responsible for the equipment and processes used in various chemical or manufacturing plants. Production Engineers ensure equipment is maintained and operating at a peak level of production and may also be involved in advising on the layout of the factory floor to maximize production levels, or on the purchase of new equipment.

Civil Engineering

Much of the physical infrastructure of our modern society is provided by civil engineers. Civil Engineers are concerned with all types of structures including dams, bridges, pipelines, roads, towers, and buildings.

Civil Engineers are responsible for the design and construction of all our transport systems, the design, and management of our gas and water supply, sewerage systems, harbors, airports, and railways. They plan, design, and test the structures of private and public buildings and facilities.

They are also involved in many environmental areas such as the assessment of the impact large-scale projects have on the environment and the collection and treatment of sewage and industrial wastes, pollution control, environmental control, and resource protection and management.

A Civil Engineer will work from an architect’s drawings and consider whether the chosen materials for a particular building will be strong enough to hold a structure of that height or design. At the same time, they would also think about how the structure might affect its surroundings. It is the responsibility of the civil engineer to produce safe, economical, and environmentally-sound structures.

Engineering disciplines

Civil Engineers may specialize as chief civil engineers, construction engineers, municipal engineers, structural engineers, transport engineers, or water supply distribution engineers.

Civil and Public Health Engineers may work in the private sector as consulting engineers, project managers, construction contractors, or in a wide range of government departments.

Work opportunities for civil engineers are affected by fluctuations in the building and construction industry. As a result, the number of opportunities may rise or fall over a short period of time.

Industrial Engineering is a science devoted to getting the best results from available resources, whilst still ensuring that the quality and expectations of the project are met.

Engineering disciplines: Marine Engineering

Marine Engineers are involved in designing, testing, and improving machinery and equipment used at sea. This machinery may include propulsion machinery, electrical, refrigeration, air conditioning, cargo handling, and domestic services equipment. It is their responsibility to check that it is all functioning effectively and being properly maintained. A marine engineer needs to have a good understanding of the way in which all these systems operate.

Marine Engineers must also become familiar with pressure vessel operation including steam-generating equipment and the associated control instrumentation. Automatic control systems are becoming more and more widely used so an understanding of computer-controlled processes is also important. Computers now mean that Marine Engineers do not have to be on constant watch in the engine room.

Marine Engineers may also work with organic pumping or mooring systems, pipelines, dockyards, port and harbor operations, and equipment for offshore oil rigs and platforms. This is a relatively small field of engineering and there tends to be a low turnover of staff. Demand is basically determined by activity in the water transport industry.

Engineering disciplines: Materials Engineering

Engineering disciplines: Mechanical and Manufacturing Engineering

Mechanical and Manufacturing Engineering turns energy into power and motion. Mechanical Engineers design, create, and improve systems and machinery that are used for domestic, public, and industrial purposes.

This area covers the design and manufacture of a great variety of products such as domestic appliances, industrial machinery, ships, aircraft, engines, pumps, compressors, and turbines or complex systems such as the air-conditioning and ventilation systems of buildings. The mechanical area interlinks closely with other areas of engineering and applies knowledge of materials, energy, and structures.

Mechanical Engineers often work in the industry designing systems and machinery that generate power, make products, move things, and help in building. They may also work in chemical processing, power generation, the automotive industry, manufacturing, building services, the aeronautical industry, defense technology, food processing, and public utilities.

Demand for mechanical Engineers depends on activity in the manufacturing and construction industries. Many graduates cross over into the field of Industrial Engineering and building services.

Manufacturing Systems Engineering is concerned with the processes and systems that are used in industry. Systems and equipment that complete tasks accurately and change raw materials into products with the smallest wastage of time, materials, and energy are designed and improved by manufacturing systems engineers.

Hydraulics is involved with the design of new and improved ways of applying fluid control so that machinery can operate smoothly and effectively with the least amount of pressure. For example, hydraulic oil pressure is used to move large cranes.

Pneumatics covers the use of air pressure to control machinery. For many industries, the air is a much safer material to use because it is clean and can be used safely in flammable areas. It is practical to use pneumatics in food processing as it is much cleaner. It is also used for safety reasons in machines that process flammable substances such as petrol and paint.

Thermodynamics deals with heat energy transfer and machinery that turns heat energy into mechanical power. Engineers in this field design, manage, and improve machineries such as boilers and gas and steam turbine generators, and facilities like cooling towers, and heating or refrigerant systems.

Minerals and Metallurgical Engineering

This form of engineering is concerned with turning raw materials of low value into valuable products, for example, bauxite into aluminum.

Minerals Engineers use a wide range of treatments to process materials in the most efficient way. This might involve physical or chemical separations and hydro or pyro-metallurgical processes.

Metallurgical Engineering takes this one step further by combining metals and non-metals to make new composite materials. These new composites are designed to be light, strong, durable, and heat-resistant materials for use in the design and performance of cars, boats, jets, spacecraft, and other vehicles.

Mining Engineering

Mining Engineers work together with geologists to investigate and carry out the extraction of ore bodies and mineral deposits, as well as the extraction of non-metallic ores and fuels such as coal and uranium.

They are responsible for planning the safest and most cost-effective way of removing minerals from the ground, rivers, or sea bed. They may be involved with designing, installing, and supervising the use of mining machinery and equipment and inspecting the progress of mining operations.

Computerized techniques are often used in the development and operation of mines. Mining Engineers are responsible for protecting conditions for both people and the environment in the vicinity of mines.

Mining Engineers work on mining sites and in the head offices of mining companies. Many mines are located in remote areas and young graduates should be prepared to travel and live in non-urban areas. Salaries for those working in the mining area are usually well above that of most other professionals and the opportunities for travel are excellent.

Experienced Mining Engineers have a wide range of career options including mine planning and design, operations management, technical specialists, contracting, consulting, the mines inspectorate, investment analysts and advisers, research, tertiary education, and general management.

Particular roles in Resource Engineering may include the estimation of water yields from catchments, flood analysis, or the design and construction of drainage and irrigation systems sympathetic to the environment.

Resource Engineers are employed by government management agencies and local government bodies, Consulting Engineers, the mining and forest industries, and Civil Engineering and construction companies.

Engineering disciplines: Risk Engineering

There is a growing awareness in the general public of the need for risk assessments to be carried out before a project begins. This involves analysis based on a knowledge of chemistry, physics, and operational aspects of any given project.

It is important to identify any potential hazards, the consequences of these hazards, and the frequency and magnitude with which they are likely to occur. These hazards need to be managed and emergency response procedures identified.

Risk consultants often carry out detailed risk assessment studies for private companies or they review studies completed by other parties.

Engineering disciplines: Software Engineering

Consider the evolution of the Internet, the growth of mobile computing, and the enormous variety of software everyone interacts with every day.

The need for engineers to create and maintain this digital world increases year by year. Software Engineers design and modify complex software systems to support the society we live in. This includes the business we conduct, the transport we take, and the games we play.

In safety-critical areas such as air travel, nuclear power plant control, medical treatment, fire detection systems, and roller coaster rides the cost of failure can be lives at risk. Other software is information-critical such as banking we conduct or medical records we update.

Software Engineering is about creating high-quality software in a systematic, controlled, and efficient manner. It is an approach to designing software to maximize quality and reliability by treating it as a formal engineering process. In a software engineering approach to building software, there is an important emphasis on analysis and design, specification and evaluation of the software.

Engineers who specialize in software can work for industries as varied as:

  • entertainment (think games development)
  • transport (e.g. fly-by-wire, autopilots, driverless trains smart ticketing, online travel booking, and check-in)
  • resources (e.g. mining software and aerial mapping/terrain modeling)
  • defense (e.g. terror attack simulations and submarine navigation)
  • medicine (e.g. diagnosis software, implant development)
  • telecommunications.

Emerging opportunities for software engineering include cyber security which is increasingly important for industry and government including utilities and other critical infrastructure, smart infrastructure and homes, and security monitoring.

The ability to make more efficient use of energy resources and create sustainable solutions increasingly depends on software engineers. Automation, control, and instrumentation in all forms of infrastructure, manufacturing, buildings, utilities, and transport will place an increasing demand on software engineers. A scan of job databases will reveal the potential careers on offer.

Engineering disciplines: System Engineering

Closely related to engineering management, systems engineering focuses on issues surrounding the design and implementation of complex systems. Systems engineers look at the big picture and take into account the entire life cycle and the surrounding ecology of a specific system, including operations, performance, test, manufacture, cost, schedule, training, support, and disposal. Applicable to nearly any discipline, systems engineers consider both the business and technical needs of stakeholders to optimize design processes.

Nearly all industries have a systems engineer or equivalent person who’s in charge of seeing the overall project perspective and liaising with leadership and regulatory professionals. The International Council on Systems Engineering (INCOSE) describes systems engineers as “responsible for the system concept, architecture, and design. They analyze and manage complexity and risk. They decide how to measure whether the deployed system actually works as intended.” These include groups that serve the needs of people, build products, create services, and provide information.

Safety Engineering

Safety engineering prevents accidents and reduces opportunities for human error in engineered environments, which means that this type of engineering applies to almost every discipline. Safety engineers ensure that buildings are structurally sound, that advanced factory systems are designed with safety at the forefront, and that workers have best-in-class clothing and equipment that protects them in specialized and hazardous environments. Whether with medical equipment, airplanes, power plants, or handheld devices, safety engineers are making sure that the priority is protecting the humans interacting with engineered technology.

While the potential for harm is universal, the three examples of safety engineers: are fire prevention and protection engineers; product safety or product compliance engineers; and systems safety engineers.

Robotic Engineering

Robotics engineers create robotic devices and the applications that run them. While manufacturing is still the primary employer in this area, robotics has moved out of the factory floor and into various industries, such as agriculture, aerospace, automotive, biomechanical, and power systems management—with new applications in new arenas being tested every day. Robotics engineers must not only learn to collaborate with many different fields of research but also learn to anticipate and envision how robotics may play a role in society.

Due to the controversial nature of robotics technology, members of the Association for the Advancement of Artificial Intelligence (AAAI), a professional society for robotics engineers, hold its members to a code of ethics and professional conduct. The code is intended for: “Anyone who uses AI technology in an impactful way and is particularly intended to act as a standard of ethical and professional conduct for all AAAI members”, providing protection for the organization’s members and the people their designs serve.

Nuclear Engineering

Nuclear engineers harness, study, and manage the power of the atom, primarily through nuclear power and radiation. Not limited to developing reactor cores, radiation shields, and power plant instrumentation, nuclear engineering also applies to medical diagnosis and treatment. Acutely trained in the tremendous power and complexity of an invisible-to-the-eye world, nuclear engineers find ways to prevent or correct nuclear power plant emergencies, safely dispose of nuclear waste, and locate and irradiate a tumor in the human body.

They design systems that employ nuclear energy, such as nuclear power plants, nuclear ships (i.e, submarine and aircraft carriers), and nuclear spacecraft.

Some nuclear engineers are involved with nuclear medicine; others are working on the design of fusion reactors that potentially will generate limitless energy with minimal minimal environmental damage.

Engineering Disciplines: Engineering Management

Engineering management is the link between the engineering world and the world of business. Engineering managers act as translators between the two worlds by interfacing with both sides and streamlining the processes and organizational structures of engineering teams and departments. Whether managing projects, products, or people, engineering managers apply the engineering mindset—i.e., developing processes that allow each element of a structure to work, in tandem—for optimal efficiency.

Because of their innate knowledge of the overall vision of a product or project development and design, shows that architectural and engineering managers (who are combined in the same occupational category) spend the majority of their time coordinating and overseeing production teams. While engineering managers work across several industries, the top employers in 2019 were manufacturing and architectural, engineering, and related services.

Engineering Disciplines: Computer Science and Engineering

Computer engineers design and develop the technical components of computers, such as microprocessors, sensors, circuit boards, memory devices, networks, and routers. As computer engineering continues to grow as a field, four sub-specializations have developed within it:

  • Computer science: This sector focuses on the algorithms and infrastructures necessary to store, synthesize, and represent information in meaningful and transmutable ways.
  • Data science: Data science takes an engineering mindset to the complications that arise from processing massive quantities of data in scientifically rigorous ways—and translates the zeroes and ones into applicable, real-world insights.
  • Cybersecurity: Cybersecurity engineers defend and repair networked systems from both outside attacks and internal corruption, using conceptual extrapolation to prepare for and prevent threats.
  • Software engineering: Software engineers design and develop software that allows end-users to interact with the underlying complexity of network systems in seamless, elegant ways, from apps to research engines and even tools that allow people and machines to communicate with one another.

Engineering Disciplines: Automotive Engineering

Automotive engineers design, test, and build land vehicles that operate in a wide variety of environments, which in turn requires an extraordinarily complex and multi-disciplinary approach. Fuel systems, thermodynamics, computer science, and industrial logistics all intersect in automotive engineering to build smarter, more efficient, and safer land transportation systems that, to the end user, feel effortless. What’s more, with the advent of autonomous vehicles, automotive engineers today benefit from an in-depth understanding of cybersecurity.

Automotive engineering work can be divided into three areas: design, research and development, and production. Notably, automotive engineers are tasked with designing the interior and exterior of new cars, testing vehicle prototypes for safety, and ensuring that consumer preferences are adhered to as well as meeting environmental and safety standards for future vehicles.
