About the role

  • 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.
  • Our pipeline of products is growing and so is our team; join us in helping to revolutionize precision heartcare.

Responsibilities

  • Deep understanding of modern distributed computing architectures and how to optimize heavy compute and cloud-data workloads (AWS, GCP, or Azure).
  • Whether you are already a seasoned tech lead or a Staff Individual Contributor (IC) ready to step up and guide a sub-team of engineers, this position gives you the platform to lead technically.

Requirements

  • Ability to write clear, well-tested, and scalable code, with high proficiency in Python.

Compensation

  • $190,000 - $250,000 base, plus cash bonus and equity.

Benefits

  • Your work will directly support large-scale machine learning applied to precision healthcare.
  • You will set the architectural vision and guide the day-to-day technical execution of the team, remaining deeply hands-on in the codebase.
  • We build Data & ML infrastructure to simplify developing, evaluating, and deploying algorithms on massive medical imaging datasets.
  • Prior experience in the healthcare domain, highly-regulated environments, or handling image-based algorithms is a huge plus.

Company info

  • 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).
  • 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.
  • Act as the technical lead and mentor for a small, high-impact team of engineers, guiding system design, conducting code reviews, and unblocking technical hurdles.
  • Write high-performance Python code and utilize frameworks like Ray to architect and maintain large-scale distributed computing platforms for ML training and evaluation.
  • Spearhead the deployment of complex ML algorithms into highly available, scalable cloud environments, ensuring models run efficiently in production.
  • Design and integrate robust cloud-data systems to manage the lifecycle of massive, unstructured medical datasets.
  • Work cross-functionally with researchers and engineers to understand how they develop models, using that understanding to solve their ML training, serving, and production monitoring needs.
  • Responsibly and securely utilize AI-powered development tools (like coding assistants or LLMs) to accelerate the team's engineering workflows.
  • We are looking for a Staff Software Engineer to act as the technical anchor for a small, focused team working on Data and ML infrastructure.
