To become a systems operator, first consider the type of system you would like to work with, as different fields may have varying requirements. A minimum of a high school diploma is typically required, though having an associate's degree or similar education and training can make you a more desirable applicant. You may also need local or national certification to work in certain fields, so research the type of work you want to do to determine if such requirements apply to you. Once you become a systems operator, expect some continued and on-the-job training to ensure you know how to perform the job required of you.
The level of education you need to become a systems operator can vary quite a bit, depending on the field in which you wish to work. To operate systems at a power plant, for example, a high school diploma may be sufficient, though some employers prefer a two-year degree or similar training in a field such as electronics or engineering. If you want to become a systems operator at a wastewater plant, then a similar degree in environmental science may be preferable. These types of educational pursuits may indicate that you are serious about working in your field and reduce the amount of training you need once you are hired.
Many of these positions require that you gain certification, which you can attain before you become a systems operator. In the US, for example, the Environmental Protection Agency (EPA) oversees certification of individuals who wish to operate wastewater management systems. Canada includes similar certification, regulated by the government, for working with drinking water. These types of certification may not be required if you want to become a systems engineer at a power plant or similar location. Look into the field you want to work and the laws and certifications necessary in your country to be sure you can gain legal employment.
Once you are trained and certified as necessary to become a systems operator, then look for work opportunities. These positions are often part of a private organization or company, so look for power suppliers and water management companies in your area. You can also expect to receive additional on-the-job training once you are hired and become a systems operator. This usually includes time reviewing different practices and learning about the procedures of your company. Many organizations also use mentoring and are likely to pair you with someone experienced while you are still new and learning the tasks expected of you.
