Full Job Description
Heartflow is a medical technology company advancing the diagnosis and management of coronary artery disease, the #1 cause of death worldwide, using cutting-edge technology. The flagship product—an AI-driven, non-invasive cardiac test supported by the ACC/AHA Chest Pain Guidelines called the Heartflow FFRCT Analysis—provides a color-coded, 3D model of a patient’s coronary arteries indicating the impact blockages have on blood flow to the heart. Heartflow is the first AI-driven non-invasive integrated heart care solution across the CCTA pathway that helps clinicians identify stenoses in the coronary arteries (RoadMap™Analysis), assess coronary blood flow (FFRCT Analysis), and characterize and quantify coronary atherosclerosis (Plaque Analysis). Our pipeline of products is growing and so is our team; join us in helping to revolutionize precision heartcare. Heartflow is a publicly traded company (HTFL) that has received international recognition for exceptional strides in healthcare innovation, is supported by medical societies around the world, cleared for use in the US, UK, Europe, Japan and Canada, and has been used for more than 500,000 patients worldwide. Coronary artery disease is the world's leading cause of death - and we're changing that. Heartflow builds AI that gives clinicians a personalized, precision 3D model of a patient's heart from a single CT scan, helping them diagnose and treat CAD earlier, more accurately, and without invasive procedures. To date, we've helped clinicians manage care for nearly 650,000 patients across more than 1,800 institutions worldwide. Every line of code we ship has a real person on the other side of it. We're looking for a Senior Software Engineer to help lead our agentic AI platform from the inside out. This is a small-team, high-ownership role - you'll be one of a handful of engineers working at the intersection of cutting-edge AI and FDA-regulated medical device software, with direct influence on how Heartflow builds and shi
