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 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 (Road Map™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.

• 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.
• Develop API‑level tests using tools such as REST Assured, Postman, Karate, Pact.io.
• Translate requirements and user stories into clear, traceable test cases in partnership with engineers, product, and RA/QA.
• Investigate test failures, file high‑quality defect reports, and partner with developers to drive issues to resolution.
• Help keep automated tests running reliably in CI/CD pipelines and respond promptly to pipeline breakages.
• Provide test evidence and documentation to support audits, CAPAs, and regulatory submissions as requested.
• Partner closely with the Test Architect and Senior Test Engineer to learn Heart Flow’s ML pipeline, clinical computation services, and Workstation/reporting systems, and grow into owning larger pieces of the automation strategy over time.

• 3–5 years of experience in software test engineering, SDET, or quality engineering roles, with a hands‑on automation focus.
• Genuine enthusiasm for AI‑assisted and emerging test automation tools and techniques, this role is as much about mindset and curiosity as it is about existing depth.
• Experience testing Software as a Medical Device (SaMD) or other regulated medical device software preferred; strong candidates from other regulated or quality‑critical environments will also be considered.
• Working familiarity with medical device QMS practices and applicable standards (e.g., ISO 13485, IEC 62304, ISO 14971, 21 CFR Part 820), including test documentation and traceability.
• Proficiency with Selenium / Web Driver and Playwright, including writing stable, maintainable UI automation.
• Hands‑on experience contributing to E2E automation suites and test frameworks.
• Exposure to authoring or maintaining test plans, protocols, and reports in a regulated environment.
• Practical use of AI‑assisted testing tools or techniques (e.g., AI‑augmented test authoring, self‑healing automation, LLM‑supported triage) or strong motivation and…
