Circadia Health is a growth-stage healthcare AI company on a mission to prevent avoidable hospitalizations and transform senior-care operations. Our Circadia Intelligence Platform combines:
Contactless sensing that monitors respiration and motion with medical-grade accuracy
Native predictive models that detect 85% of preventable adverse events several days in advance
Enterprise integrations that operationalize predictions directly inside EHR care-coordination billing and compliance workflows
Today our technology touches 40000 post-acute patients daily across skilled-nursing home-health and home-care networks. We are backed by leading healthcare and AI investors and headquartered in El Segundo CA.
The Role
As a Staff Software Engineer you will play a critical role in designing developing and maintaining both backend APIs and frontend applications that support sensitive healthcare platforms. You will be proficient in Python for backend development and have experience with modern frontend frameworks such as ReactJS or Angular. Your expertise in Test-Driven Development (TDD) security best practices and comprehensive documentation will ensure the reliability scalability and security of our mission-critical software. Your work will directly impact patient care and enhance the efficiency of clinical staff by contributing to a platform that serves 30k patients daily through our Circadia Contactless Monitor (IoT devices)a number expected to scale beyond 100k in the next 2 to 3 years.
What Youll Do
Frontend Development:
Build develop and maintain responsive interactive user interfaces using modern JavaScript frameworks (React Angular).
Implement state management and develop reusable UI components for seamless integration with backend services.
Optimize frontend performance using techniques like lazy loading code splitting and caching.
Ensure cross-browser compatibility and adherence to WCAG guidelines for accessibility.
Backend/API Development:
Design develop and maintain RESTful APIs using Python (FastAPI) to support healthcare applications.
Collaborate with frontend and mobile developers to integrate APIs effectively.
Ensure APIs are secure scalable and performant to handle increasing loads.
AWS Expertise:
Build scalable applications using AWS services (Cognito Pinpoint IoT MSK).
Expand and manage services under AWS modules while implementing robust authentication protocols.
Navigate Docker deployments to scale containerized applications efficiently.
Test-Driven Development (TDD):
Write unit tests and integration tests using PyTest to ensure code quality and reliability.
Conduct code reviews and implement best practices for high coding standards.
Data Management:
Manage patient data efficiently using databases (MySQL PostgreSQL MongoDB).
Optimize database queries for performance and scalability while ensuring data integrity.
Security and Compliance:
Implement and maintain security measures to protect sensitive healthcare data.
Ensure compliance with healthcare regulations including HIPAA.
Regularly update and patch API endpoints to address vulnerabilities.
Documentation and Collaboration:
Create and maintain comprehensive documentation for APIs workflows and best practices.
Maintain detailed change logs version histories and onboarding guides.
What Great Looks Like (Example Profile)

Built scalable ingestion pipelines for high-frequency time-series data
Led EHR or healthcare integrations (HL7/FHIR) in production
Reduced infrastructure costs while improving system reliability
Designed multi-region failover or high-availability architectures
Improved CI/CD velocity and reduced incident frequency materially
Youll Thrive Here If
You think in systems and failure modes
You proactively eliminate technical debt before it compounds
You enjoy designing durable infrastructure more than flashy UI
You hold high standards and elevate those around you
You take pride in building systems that just work at scale
