Job description

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.

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, Vue.js, 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 You'll Do
Frontend Development:
  • Build, develop, and maintain responsive, interactive user interfaces using modern JavaScript frameworks (React, Vue.js, 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)

  • Designed backend systems supporting 50K-500K+ users or devices
  • 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

You'll 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
Must-Have Qualifications

  • Advanced knowledge of Python and related frameworks (FastAPI, NumPy, Pandas, Pydantic) including multithreading and parallel design principles

  • Expertise in JavaScript and frameworks such as ReactJS, with solid frontend experience

  • Strong understanding of RESTful API design principles, best practices, and HTTP(S) as a protocol

  • Understanding of AWS, including knowledge of Cognito, Pinpoint, IoT, MSK and other services, with hands-on containerized deployments via Docker

  • Experience with relational and NoSQL databases (MySQL, PostgreSQL, MongoDB)

  • Experience with TDD and testing frameworks such as PyTest

  • Deep understanding of user-centered design principles, design thinking methodologies, and usability best practices

  • Understanding of security best practices and compliance in regulated environments

  • 2+ years tenure in most recent roles

  • Top education and top schools/companies

Nice-to-Haves

  • Proficiency in C++ and TypeScript

  • Experience with Qt preferred but not required

  • Experience with Google APIs is preferred

  • Experience with AWS-specific services: Cognito, IoT, Pinpoint, Kafka/MSK

  • Familiarity with HIPAA compliance and healthcare application development

  • Experience with CI/CD tooling: Jenkins, CircleCI, Prometheus, Grafana

  • Background in regulated industries (healthcare, life sciences, medical devices)

  • 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

  • Detail-Oriented: Ability to maintain high levels of accuracy and attention to detail, particularly when developing APIs that handle sensitive healthcare data

  • Communication and Trust: Exceptional communication skills with the ability to collaborate effectively across teams and maintain the highest levels of confidentiality

  • Organization and Efficiency: Capable of managing multiple projects and timelines simultaneously with a keen eye for detail

  • Growth Mindset: Ability to learn from mistakes, demonstrate curiosity and resilience in the face of setbacks, and constantly seek to improve and grow

Technologies and Tools:
  • Programming Languages: Python, Javascript,  C++ (Optional)
  • Frameworks: FastAPI, NumPy, Pandas, Pydantic, ReactJS
  • Databases: MySQL, PostgreSQL, MongoDB
  • Testing: PyTest
  • Version Control: Git
  • CI/CD: Jenkins, CircleCI
  • Documentation: Confluence, Markdown
  • Monitoring: Prometheus, Grafana
