About Circadia Health
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:
  1. Contactless sensing that monitors respiration and motion with medical-grade accuracy
  2. Native predictive models that detect 85% of preventable adverse events several days in advance
  3. Enterprise integrations that operationalize predictions directly inside EHR, care-coordination, billing, and compliance workflows
Today, our technology touches 40,000+ 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.

  • 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.

Must-Have Qualifications
  • Advanced knowledge of Python and related frameworks (FastAPI, NumPy, Pandas, Pydantic) including multithreading and parallel design principles.
  • Understanding of AWS, including knowledge of Cognito, Pinpoint, IoT, MSK and other services.
  • Expertise in Javascript and frameworks such as ReactJS
  • Deep understanding of user-centered design principles, design thinking methodologies, and usability best practices.
  • Knowledge of HTTP(S) as a protocol
  • Proficient in using and maintaining Docker containers.
  • Strong understanding of RESTful API design principles and best practices.
  • Experience with TDD and testing frameworks such as PyTest.
Nice-to-Haves
  • Proficiency in C++, TypeScript
  • Experience with Qt preferred but not required
  • Experience with Google APIs is preferred.
  • Design Acumen: Deep understanding of user-centered design principles, visual hierarchy, and interaction design fundamentals. Proficiency in translating complex healthcare workflows into intuitive, user-friendly interfaces.
