As an engineering technician, your job is to perform the labor requested by senior engineers. To do this, you may help with the construction of various devices, provide input on mechanical design, and ensure that the labs have the necessary supplies. Depending on the needs of the project, you may also develop how-to guides for getting the job done, perform quality control measures, and test your results to ensure everything meets the intended standards. Most engineering technicians specialize in a particular field, such as chemical, biomedical, or civil engineering. Expect to frequently use computer-aided design software, perform mathematical calculations, and write reports that summarize your collected data.
