About the Role

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.

Responsibilities

Design and develop HeartFlow’s interoperability services, creating a technical bridge between complex, on-premise hospital Electronic Health Record (EHR) systems and our AWS cloud environment.
Implement data modeling and persistence strategies to structure complex clinical data for a comprehensive, unified platform for managing heart disease.
Build and maintain critical data acquisition and ingestion pipelines, ensuring seamless, scalable, and secure extraction and normalization of patient data from diverse hospital networks.
Build highly reliable, secure, and low-maintenance APIs (leveraging REST alongside healthcare standards like FHIR and HL7) to securely connect on-premise hospital components to our cloud infrastructure.
Follow software development best practices and ensure data flows and system integrations adhere to FDA and other regulatory body standards.
Mentor more junior engineers and contribute to system design discussions.

Requirements

Strong Python development proficiency.
Experience applying Domain-Driven Design (DDD) principles.
Experience architecting robust microservices and event-driven architectures at scale.
Experience integrating with Electronic Health Record (EHR) systems.
Experience utilizing healthcare data standards (e.g., FHIR, HL7).
Experience with data modeling and architecting scalable persistence layers for complex, high-volume data systems.
Experience building within modern cloud ecosystems.
Experience designing secure RESTful APIs and applications.
Experience mentoring engineers, contributing to system design, and establishing rigorous software development best practices and testing strategies.
Experience designing testable systems and leading comprehensive testing strategies (Unit, Functional, and System-level) for mission-critical applications.
Passion for realizing the vision of a single, unified platform to manage and treat heart disease.
Passion for championing high-quality software, rigorous development processes, and elevating the technical baseline of the entire team.
Passion for taking ownership of features and components, operating with autonomy while growing toward broader architectural responsibility.
Passion for fostering a culture of open communication, speaking up when faced with challenges, and guiding healthy technical debates.
Passion for pragmatically evaluating and applying state-of-the-art technologies to solve complex interoperability and scaling challenges.
Excited to advance the frontier of Software as a Medical Device (SaMD) and data acquisition in the cardiology space.
Excited to navigate and innovate within strict regulatory environments (FDA, HIPAA) to securely deliver life-saving medical applications.
Excited to solve novel challenges in distributed, highly available, and resilient systems for mission-critical healthcare operations.

About the Company

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.
