A service engineer, also called a field service engineer, installs, repairs, and maintains equipment for clients. As a service engineer, you are the face of your company, traveling on-site to troubleshoot the issues your client has with the machinery. Depending on where your client is located, you may work in offices, factories, or health care facilities; indoor or outdoor areas; locally or overseas. You may specialize in a particular industry or type of equipment, but you need to have broad knowledge of mechanical, electrical, and technological principles. Service engineers may also collaborate with design teams to configure the proper machinery to fit each client’s needs and train employees in the organization to use the equipment.
