As an elevator engineer, your responsibilities are to install and repair elevators. You service the mechanical components using job-specific equipment, acting as a technician for any company that utilizes an elevator. Other duties require you to assemble parts, plan installations, and ensure the proper operation of an elevator. An elevator engineer might also work with escalators, lifts, and moving walkways. Fixing electrical wiring is a significant part of your job, so you must understand components like brakes and motors. You may work for a single organization or in a freelance capacity.
