Staff / Principal Full Stack Engineer

About Chamber:

Cardiovascular disease remains the leading cause of death in America. At Chamber, we’re rebuilding the system for cardiology — creating a world where outcomes, not volume, define success. We partner with independent cardiologists to help them lead population health efforts in their communities, equipping them with technology, data, and operational tools that turn complex insights into better care for patients.

Our model blends clinical expertise, thoughtful design, and a modern operating platform that supports physicians, patients, and payers alike. We believe innovation and empathy go hand in hand, and by combining cutting-edge AI tools with a relentless focus on human care, we can transform heart health at scale.
Role Overview:
The Staff / Principal Full Stack Engineer will play a central role in designing and building Chamber’s core application platform. This is a hands-on role for someone who thrives in a startup environment, enjoys solving complex product and data challenges, and is excited to build systems that make a difference in healthcare.

This role will help design and build the web applications that power Chamber’s operational tools for care teams and healthcare providers. These applications support real-time cardiology insights and value-based care workflows, combining clinical data, analytics, and AI-assisted features.

The role will work across the stack—from modern web interfaces to backend services and API integrations—partnering closely with product, data, and infrastructure engineers to deliver reliable, high-impact software. This role will have a meaningful influence on application architecture, engineering practices, and the evolution of Chamber’s product platform.
