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. The Senior Test Engineer is a hands-on individual contributor on the Test Engineering team, responsible for end-to-end system testing, post-deployment verification, and the design and execution of automated test suites that protect the quality of our regulated SaMD products. This role takes an AI-first approach to test automation — using AI-assisted tooling to accelerate test authoring, triage, and maintenance — while applying the rigor required of a medical device environment. The ideal candidate brings deep technical expertise in modern UI automation frameworks (Selenium and Playwright), experience writing test plans and validating tools under a QMS, and a track record of shipping high-quality software in a regulated SaMD context. Responsibilities Design, implement, and maintain end-to-end (E2E) automated test s
