Email communication from The Greenbrier Companies (Greenbrier) will always come from a corporate email address that ends in @gbrx.com or from our applicant tracking system, ADP, after you have created a secure account and submitted your application. During the application process, which is accessed through this careers.gbrx.com website or through our secure applicant tracking site that begins with https://recruiting.adp.com, you will create a secure account where we will ask you to provide your contact information, past employment history, education history and other job-related information.
