If click further on the title of the webpage https://app.trinethire.com/companies/14003-g-medical-diagnostic-services/jobs/11488-certified-cardiac-monitoring-technician?source=Glassdoor , it comes up with a list of "Careers at G Medical Diagnostic Services/Our Current Job Openings" in different locations in US (understand Headquartered in Austin, TX), sorry can't explain myself, might be some posters here who looked into this in depth before may be able to help explain a bit. There are some US related info that can be found in https://gmedinnovations.com/wp-content/uploads/2017/10/GMV_G_Medical_Purchases_CardioStaff_Diagnostic_Services_Inc.pdf AND recent https://www.asx.com.au/asxpdf/20190730/pdf/44707524qwczp7.pdf
