Mechanical engineering technicians usually work in workshops, factories, power plants, building sites or offices. In Western Australia, they usually work in the Perth metropolitan area and some regional areas. The work environment can be noisy and dirty, and some of the machinery may potentially be dangerous. There are often strict safety procedures that must be followed to minimise the risk of working with heavy machinery. Work hours can vary significantly, depending on the employer and type of work being conducted. Some mechanical engineering technicians may work shifts, which can include nights and weekends. Many work on a Fly in/Fly out basis.

Mechanical engineering technicians usually use Computer-Aided Design (CAD) software when drawing up new plans or blueprints. When installing new equipment or carrying out maintenance they may use a variety of hand and power tools. Safety equipment may include steel-capped boots, safety googles, hard-hats, overalls, high-visibility clothing, gloves and hearing protection.
