Test Engineer III

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 FFR CT 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 (FFR CT 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 Test Engineer is a hands-on individual contributor on the Test Engineering team, responsible for executing and extending automated test coverage across our regulated SaMD products.

This role focuses on end-to-end system testing and post-deployment verification, working closely with and taking technical direction from the Test Architect and Senior Test Engineer while bringing fresh energy and fluency in modern AI-assisted tooling to accelerate the team's automation strategy. We're looking for someone genuinely excited by new testing technology, someone who will experiment with the latest AI-assisted authoring, self-healing, and triage tools, bring ideas back to the team, and help the function move faster, all while operating with the rigor required of a medical device QMS environment. The ideal candidate is comfortable with modern UI automation frameworks (Selenium and Playwright), motivated to grow their depth in regulated software testing, and driven by the chance to ship high-quality software that directly supports patient care.

Responsibilities

Build and maintain automated end-to-end (E2E) tests covering complete user workflows across UI, API, and back-end services, under the technical direction of the Test Architect and Senior Test Engineer. Actively explore and apply AI-assisted test automation techniques AI-assisted authoring, self-healing locators, generative test design, and AI-supported triage and bring back recommendations on new tools and approaches worth adopting team-wide. Execute post-deployment verification activities such as production smoke tests and monitoring-driven checks, including contributing to a new baseline of daily smoke tests across environments.

Contribute to test plans, test protocols, and test reports under the guidance of senior engineers, ensuring documentation meets QMS expectations. Participate in tool validation activities for test infrastructure and automation tooling per internal procedures. Implement and maintain UI test automation using Selenium and Playwright; follow established framework patterns and contribute improvements and modernization ideas.
