Online mechanical engineers design and develop tools, machines, engines, thermal sensors, and other mechanical devices. Instead of working in the office, online mechanical engineers complete their job duties remotely, either from home or another location outside of the office with internet connectivity. As an online mechanical engineer, you discuss the scope of the project with your client, develop a design to meet the required specifications, and collaborate with your client to plan the production of the device. Though this is a remote position, you may need to travel to the project site to oversee the process of building the equipment and test it to ensure it works properly. Online mechanical engineers may work for an engineering firm, or they may be independent contractors who work with many different clients.
