Electronics engineering technicians assist electronics engineers with research, design, manufacturing, operation and maintenance tasks. They may work under the direction of electronics engineers, technologists or associates in all stages of planning, design, maintenance and production.

Engineering managers plan, administer and review engineering and technical operations.

Fabrication engineering tradespersons cut, shape, join and finish metal to make, maintain or repair metal products and structures. They may produce moulds or patterns for metal castings, apply coatings and work with a variety of materials.

Mechanical engineering tradespersons carry out a range of mechanical work on machines, subassemblies and manufactured parts using a range of processes, tools and machines. Recent changes in the industry have resulted in a number of trade jobs being merged into broad occupational areas. The new training structure provides a mix of skills across a number of traditional occupations, while also allowing apprentices to develop specific skills.

Environmental engineers are concerned with assessing and managing the effects of human and other activity on the natural and built environment. They apply their engineering knowledge and skills to such things as environmental impact assessment, natural resources management and pollution control.

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.

Industrial engineers plan, organise, supervise and manage the operations of industries to ensure the economical, safe and effective use of materials, energy and people.

Industrial engineering technologists study and try to improve the quality and quantity of goods produced, and the efficiency and economics of production.
