Field engineers must have in-depth understanding of technological services their company provides, including installing, maintaining, and replacing the machines. They repair / replace the parts of the machinery as needed. Because of that, field engineers travel a lot to different locations - wherever their services are needed.
That is by no means their only role. Field engineers also design all necessary modifications in order to maximize efficiency and safety. Depending on their professional background, some engineers may also be in charge of verifying product prototypes, developing and implementing technology procedures, and examining products for any potential flaws.
Further out, field engineers provide technical support on project evaluation, design, installation, and maintenance. They analyze costs and the demand in order to come up with optimum project recommendations. Their professional guidance is welcome both by clients and staff when it comes to technical issues.
