We anticipate the application window for this opening will close on - 2 Nov 2026   Careers that change lives start here. Medtronic is a global leader in healthcare technology with a Mission to alleviate pain, restore health, and extend life. Our 95,000 employees work across more than 150 countries to put patients first — developing innovative medical technologies that improve the lives of 72+ million patients each year. Your unique talents will help shape the future of healthcare while building a career grounded in purpose, growth, and impact. A Day in the Life The Affera Mapping and Ablation System is an innovative medical technology designed to treat patients with cardiac arrhythmias. The system involves advanced mapping techniques to create detailed images of the heart's electrical activity, helping physicians identify abnormal areas causing arrhythmias. Once identified, the Affera Ablation System delivers targeted energy to disrupt these abnormal signals, restoring normal heart rhythm. This position follows Medtronic’s minimum four-day-per-week onsite work model.                     As a Sr. Mechanical Design Engineer in CAS Research & Technology (R&T), you will support the initial design of electrophysiology devices for use with the Affera system.
