A stationary engineer's job duties include repairing and maintaining equipment such as generators, pumps, refrigeration units and air conditioning. Stationary engineers also monitor and regulate equipment to ensure safety and to avoid potential mechanical problems. The workplace setting ranges from malls and warehouses to large commercial office buildings that contain complex heating and air conditioning systems. According to the Bureau of Labor Statistics, employment is expected to grow more slowly than average throughout 2010 - 2011. A stationary engineer must obtain proper licensing in order to operate certain types of equipment on the job.

The union apprenticeship program corresponds with colleges and vocational schools for licensing. Throughout the program, apprentices receive both classroom and on-the-job training from experienced union stationary engineers.
Find out your state's exam requirements for receiving state licensing outside of the union route. Take the appropriate examinations at a local college or vocational school to receive the stationary engineer license. Each state's exam requirements vary by region. Most states offer up to five levels of licensing for stationary engineers. Your work experience determines the level and examination you need to take.
