Machines are the most common things found in all power plants, factories, and other industrial facilities; big, heavy, and complicated machines. Installing, operating, and providing maintenance to all this complex equipment is part of a Millwright’s job. Along with Industrial Engineers, Millwrights are the people tasked with ensuring the proper functioning of every machine and system involved in the daily routines and tasks of any industry.

The term “Millwright” comes from the time where people depended on wind or water mills to produce and obtain products such as flour, paper, and other goods. In many ways, mills are the predecessors of today’s industrialized machinery. Back then, Millwrights were the people in charge of building, operating, and fixing these mills. In today’s world, modern machines have taken the roles that were previously performed by mills, yet the name given to the people in charge of these machines stuck.

Most employers require applicants to have completed at least a secondary school education or to have a General Educational Development (GED) certificate, as well as an apprenticeship program that can be taken at specialized vocational schools and community colleges. These programs are mostly based on supervised practice under an experienced Millwright who provides aspirants all the information they need to perform this job.

Although not obligatory, Millwrights can join the United Brotherhood of Carpenters and Joiners of America in order to get employment benefits, as it will easier for them to find a job, to get medical care, annuities, a pension, among others.

Millwrights don’t have an established schedule as they are likely to work on a contract basis. Therefore, they can spend several weeks working on the same project, but they can also be unemployed for short periods of time, while the next project arrives. Therefore, they need to be able to appropriately manage their finances and time.
