Food technologists develop and improve existing food products and set standards for producing, packaging and marketing food. They use chemistry, microbiology, engineering and other scientific methods to study the process of food deterioration. They may specialise in fields such as meat, dairy, seafood, cereal products, confectionery, snack foods, beverages and minimally processed fresh produce.
Garbage collectors collect household, commercial and industrial waste for disposal or recycling.
Geological engineers identify and try to solve problems involving soil, rock and groundwater, and design structures in and below the ground, using the principles of earth science. Geological engineering includes a number of ground engineering specialities such as geotechnical engineering, land remediation, rock mechanics, groundwater hydrology and engineering geology.
Home improvement installers put in place home improvements such as awnings, curtains, blinds, flyscreens, garage doors, exterior cladding, shower screens and prefabricated windows and doors.
Industrial designers create and produce designs for commercial, medical and industrial products. They also make models and prototypes of these designs for mass production. The products that industrial designers create cover a wide range of manufactured goods, from toys and toasters to furniture and heavy machinery. Some work is carried out on the development of new products. Other work is related to updating and improving the design of existing products.
Industrial engineers plan, organise, supervise and manage the operations of industries to ensure the economical, safe and effective use of materials, energy and people.
Instrumentation tradespersons install, modify, maintain and repair instrumentation used in measurement and control systems. These instruments measure and control temperature, pressure and flow in processes used in industries such as petro-chemical, mining, food and manufacturing.
Intelligence analysts evaluate information from a variety of classified and unclassified sources. This information is often incomplete, contradictory and can vary widely in terms of reliability. Depending on their background and qualifications, an intelligence analyst may examine a diverse set of countries, issues (such as terrorism) and cultures. Intelligence analysts working for the Department of Defence specialise in a number of areas depending on their training, qualifications and agency employment.
Laboratory workers assist scientists, engineers, technical officers and other laboratory staff by collecting and preparing samples, carrying out experiments, making measurements with scientific equipment, recording results and presenting them for critical analysis.
Materials engineers investigate the properties of metals, ceramics, polymers, plastics and other materials, and develop and assess their commercial and engineering applications. Materials engineers may specialise in metals, ceramics, polymers, plastics or composites.
Mechanical engineers plan, design and oversee the development, installation, operation and maintenance of machinery. They conduct research to solve practical engineering problems and improve efficiency.
Mechanical engineering associates assist mechanical engineers and engineering technologists with the design, manufacture, construction, operation and maintenance of machines, manufacturing equipment, mechanical installations and mechanical facilities. They usually have a range of duties carried out under the direction of mechanical engineers and engineering technologists.
