Software Engineer, Algorithms

HeartFlow, Inc. 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 VC-backed company 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 250,000 patients worldwide.

• Good troubleshooting and diagnostic skills.
• Exposure to containerization technologies (Docker, Kubernetes) is a plus.
• Strong collaborative and communication skills.

How You Stand Out:

• Experience or coursework in medical imaging, computer vision, or 3D computational geometry.
• Familiarity with developing software in regulated environments (FDA, MDR) is a plus.
• Interest in cloud-based ML model deployment and collaborating with ML research teams.
• Knowledge of statistical methods, image optimization techniques, or visualization tools.
