Staff Software Engineer, Algorithms

HeartFlow, Inc. 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 VC-backed company 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 250,000 patients worldwide.  

We are looking for a seasoned Software Engineer passionate about creating innovative algorithmic solutions that enhance healthcare. This role combines hands-on algorithm development with cloud and DevOps responsibilities, driving the technical evolution of our healthcare platform to deliver impactful patient outcomes. If you have expertise in algorithm design, scalability, and enjoy tackling technical challenges in a collaborative environment, join our team.

Why Join Us: You’ll work on products that directly improve patient care.

• Strong knowledge of cloud infrastructure, particularly AWS, including service configuration and qualification.
• Proven experience in software development best practices: testing, CI/CD, DevOps, and agile methodologies.
• Experience with infrastructure-as-code tools such as Terraform, Chef/Ansible, and orchestration with GitHub Actions or similar tools.
• Expert-level troubleshooting and diagnostic skills across applications, networks, and cloud environments.
• Experience leading technical projects, balancing both software development and cloud infrastructure aspects.
• Strong hands-on experience with containerization (Docker, Kubernetes).

How You Stand Out:

• Experience in medical imaging, computer vision, and 3D computational geometry.
• Experience developing medical software in regulated (FDA, MDR) environments, including working with quality and regulatory teams.
• Familiarity with cloud-based ML model deployment and working with ML research teams to scale and productize solutions.
• Deep knowledge of statistical methods, image optimization techniques, and visualization tools.
