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 suites that exercise complete user workflows across UI, API, and back-end services.
  • Apply an AI-first approach to test automation: leverage AI-assisted authoring, self-healing locators, intelligent test triage, and generative techniques to scale coverage and reduce maintenance burden.
  • Lead post-deployment testing activities, including production smoke tests, monitoring-driven verification, and continuous validation against live environments.
  • Author clear, traceable test plans, test protocols, and test reports that meet the documentation expectations of a regulated medical device QMS.
  • Perform tool validation for test infrastructure and automation tooling in accordance with internal QMS procedures and applicable standards.
  • Build and maintain UI automation using Selenium, Vitest and Playwright; extend frameworks for stability, parallelism, and reuse across product lines.
  • Collaborate with software engineering teams to standardize API-level and integration tests using tools such as REST Assured, Postman, or Karate, and contribute to contract testing where appropriate.
  • Partner with software engineers, product managers, and RA/QA to translate requirements into verifiable test cases with full traceability.
  • Triage and root-cause failures across complex distributed systems; drive defects to resolution and contribute to defect-prevention initiatives.
  • Contribute to CI/CD pipelines so that automated tests run reliably and provide fast, actionable feedback to engineering teams.
  • Support quality-related audits, CAPAs, and regulatory submissions by providing test evidence, traceability, and documentation.
  • Support offshore test engineers for overlapping product areas.
Qualifications
  • 5-8 years of experience in software test engineering, SDET, or quality engineering roles, with a strong hands-on automation background.
  • Required: Direct experience testing Software as a Medical Device (SaMD) or other regulated medical device software.
  • Required: Working knowledge of medical device QMS practices and applicable standards (e.g., ISO 13485, IEC 62304, ISO 14971, 21 CFR Part 820), including test documentation, traceability, and tool validation.
  • Required: Strong proficiency with Selenium / WebDriver and Playwright, including framework design, page-object patterns, and stability/flake reduction techniques.
  • Demonstrated experience designing and maintaining E2E automation frameworks that cover complete workflows and system integrations.
  • Experience authoring test plans, protocols, and reports in a regulated environment, with attention to traceability between requirements, test cases, and evidence.
  • Practical experience with AI-assisted testing tools and techniques (e.g., AI-augmented test authoring, self-healing automation, LLM-driven test generation or triage).
  • Solid programming skills in at least one mainstream language used for automation (e.g., TypeScript/JavaScript, Python, Java, or C#).
  • Experience with API testing tools (REST Assured, Postman, Karate, or equivalent) and basic familiarity with contract testing concepts.
  • Experience integrating automated tests into CI/CD pipelines (e.g., GitHub Actions, Harness) and working with cloud environments such as AWS.
  • Strong analytical and debugging skills across distributed systems, with a structured approach to root-cause analysis.
  • Excellent written and verbal communication skills; able to clearly document test designs, defects, and risk.
  • Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
Desired
  • Experience supporting RA/QA teams during regulatory audits and inspections.
  • Experience testing ML/AI systems, clinical validation workflows, or medical imaging products.
  • Experience validating complex visualizations (qualitative and quantitative) such as 3D models, overlays, or measurement views.
  • Experience generating and managing diverse test datasets (synthetic, anonymized, adversarial).
  • Familiarity with non-functional / performance testing tools (e.g., k6, Locust, JMeter, Gatling).
  • Exposure to data-pipeline testing and microservices architectures.
