Mechatronics engineers help design and manufacture new technology, parts, tools, and machine control systems for production manufacturing. Your duties include analyzing and assessing automated production and determining ways to improve productivity and efficiency through the introduction of new tools. You visit assembly lines, observe machinery, and then make suggestions for ways to engineer new machines that will speed up production. You and your team must take into consideration many different elements of the production process in order to build a tool or machine that will be easy to use while also improving assembly-line efficiency.
