Heartflow•San Francisco, CA

12d

About The Position

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. This position plays a key engineering role in realizing HeartFlow’s vision of creating a single, comprehensive platform to manage heart disease. As a Senior Software Engineer, you will help design and build the architecture and data modeling for a next-generation distributed system that seamlessly and securely integrates HeartFlow’s cloud services with complex, on-premise hospital Electronic Health Record (EHR) systems. You will own the design and delivery of significant components within the interoperability domain, improving how clinical data is processed, modeled, and delivered. Operating at the senior level, you will contribute to architectural decisions for key components, mentor more junior engineers, and apply robust software development best practices. You will help ensure that the platform’s foundation scales efficiently and adheres to the compliance, security, and quality standards set forth by the FDA and other regulatory bodies.

Requirements

Strong Python development proficiency, applying Domain-Driven Design (DDD) principles, and architecting robust microservices and event-driven architectures at scale.
Integrating with Electronic Health Record (EHR) systems and utilizing healthcare data standards (e.g., FHIR, HL7).
Data modeling and architecting scalable persistence layers for complex, high-volume data systems.
Building within modern cloud ecosystems and designing secure RESTful APIs and applications.
Mentoring engineers, contributing to system design, and establishing rigorous software development best practices and testing strategies.
Designing testable systems and leading comprehensive testing strategies (Unit, Functional, and System-level) for mission-critical applications.
Bachelor's degree in Computer Science, Engineering, or related discipline, or equivalent experience.
8+ years of relevant industry experience
