What is a QA Engineer at ZOLL Medical?

A QA Engineer at ZOLL Medical plays a vital role in the development and manufacturing of life-saving medical devices and software solutions. Because these products—ranging from defibrillators and cardiac monitors to ventilators and automated CPR systems—are deployed in critical care environments, product quality is quite literally a matter of life and death. The work you do directly impacts first responders, medical professionals, and patients worldwide, making this role both highly rewarding and exceptionally demanding.
