Engineer - Product Investigations

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 750,000 patients worldwide.  

As a Principal Engineer with expertise in CT, plaque, and FFRct (Fractional Flow Reserve derived from Computed Tomography), you will be the technical lead for Heartflow's most complex product investigations arising from complaints and other sources of post-market information.    

As a Principal Engineer - Product Investigations, you will not handle first-line investigations. Instead, in this unique role, you will lead and resolve escalated or complex technical investigations for Heartflow's AI/ML coronary artery disease products, including FFRct Analysis, Plaque Analysis, and PCI Navigator, partnering closely with Research, Software Engineering, Product Management, and Medical and Clinical Affairs teams.  This role will report to the Director of Post-Market Quality.  Your investigations and conclusions on challenging technical topics will inform regulatory reportability decisions, drive corrective actions, and feed directly back into how our products are designed and improved. If you are energized by getting to the true root cause(s) of difficult technical problems and partnering across R&D, Medical, Clinical, Regulatory, and Quality to serve patients, we want to hear from you.

Key Responsibilities

• Lead end-to-end technical investigations of products involving Heartflow's AI/ML-enabled SaMD products, including alleged accuracy issues, discrepancies with invasive or reference measurements, and software anomalies.
• Reconstruct and analyze case-level evidence, including CCTA inputs, model outputs, processing logs, case analyst workflow records, and software version history, to establish robust root cause(s) and recommend corrective and preventive actions.
