## Job description

About Circadia HealthCircadia Health is a growth-stage healthcare harwdare & AI company on a mission to prevent avoidable hospitalizations and transform senior-care operations. Our AI Care System combines: Contactless sensing that monitors respiration and motion with medical-grade accuracy — powered by our own in-house-designed monitoring devices, developed from the radar hardware up 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 40,000+ post-acute patients daily across skilled-nursing, home-health, and home-care networks. Because we build our own sensing hardware and the algorithms that run on it, our signal processing work reaches from raw radar waveforms all the way to clinical decisions. We are backed by leading healthcare and AI investors, with offices in Los Angeles and London.

## About the Role

We're looking for a research engineer with deep signal processing expertise to develop the algorithms that turn raw sensor data into clinically meaningful measurements. You'll work across the full path from research to deployment — from novel algorithm development through validation on clinical data to implementation on embedded devices in a shipping product, in close collaboration with the team designing our sensing hardware.

## What you'll do

- Develop novel signal processing algorithms for Circadia's contactless monitoring system (radar and other sensors)
- Research signal processing techniques — and, where useful, machine learning — to extract clinically relevant features from sensor data
- Process data from clinical studies to develop and validate product features
- Prepare algorithm documentation for regulatory compliance and IP protection
- Implement algorithms for execution on embedded devices
- Work with the Product, Clinical Research and Engineering teams (Algorithms, Data Science, Electronics, Firmware) to align on requirements
- Provide regular progress updates and reports to management

## About you

- MSc or PhD in signal processing, electrical engineering, biomedical engineering, or a related field
- Strong, demonstrable expertise in signal processing — this is the core of the role
- Industry work experience as an algorithm or signal processing engineer (beyond academic research)
- A track record of building algorithms that have been deployed in real products — not solely offline processing of research datasets
- Experience working with biosignals or physiological sensor data
- Experience with sensor characterization and configuration
- Comfortable across the research-to-deployment path, including implementing algorithms on embedded/constrained devices
- Able to communicate clearly across research, clinical and engineering teams

## Nice to have

- Familiarity with machine learning, or experience combining signal processing and ML approaches
- Experience with radar or other contactless sensing
- Familiarity with medical device regulatory requirements or working in a regulated environment

## About Circadia Health

## Company Overview
- **One-liner**: Circadia Health provides the world’s first FDA-cleared contactless patient monitoring platform that uses radar and AI to detect early signs of clinical deterioration in senior care settings.
- **Entity Type**: Private (total funding $100.4M, multiple rounds including seed, convertible notes, and product crowdfunding)
- **Headquarters**: Los Angeles, California, United States
- **Founded**: 2016
- **Founders**: Michal Maslik (CTO & Co-Founder); other co-founders not publicly named in available sources

## Core Business
- **Primary industry**: Medical Equipment Manufacturing / Healthcare Technology
- **Target customers**: B2B – skilled nursing facilities (SNFs), senior living communities, home health agencies, and healthcare providers serving elderly populations
- **Mission statement**: “Reduce rehospitalizations by helping providers see changes in their patient’s health before they worsen and disrupt treatment.” [circadia.health/about](https://circadia.health/about)

## Products & Services
- **C200 Device**: FDA-cleared contactless monitoring device that uses radar and proprietary algorithms to detect heart rate, respiratory rate, bed exits, and motion. Includes two-way audio for patient communication. [circadiahealth.com](https://circadiahealth.com/)
- **Clinical Intelligence Platform**: Cloud-based software providing predictive analytics, real-time alerts, and daily risk reports powered by AI and machine learning. Integrates with electronic health records.
- **Virtual Nurse Monitoring Service**: A team of virtual nurses reviews device data and patient records 24/7/365 to deliver personalized, predictive risk alerts, enabling early intervention.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of $100.4M (latest reported convertible note of $100M in 2017, plus seed and earlier rounds) [linkedin.com](https://www.linkedin.com/company/circadia)
- **Notable Investors**: Village Global (led seed round, backed by Bill Gates, Jeff Bezos, Mark Zuckerberg) [apply.workable.com](https://apply.workable.com/circadia-health/)
- **Growth Signals**:
  - 30K+ patients monitored per day [circadiahealth.com](https://circadiahealth.com/)
  - 30% reduction in rehospitalizations reported
  - 78 employees (+35.6% YoY), with presence in 6 countries [linkedin.com](https://www.linkedin.com/company/circadia)
  - Active hiring: 10 open positions, job postings up 400% YoY
  - $316K yearly ROI per 100-bed SNF claimed

## Competitive Advantages
- **First-mover with FDA clearance**: Only contactless monitoring system cleared by the FDA for heart rate, respiratory rate, and motion without any body-worn sensors.
- **Proprietary radar + AI**: Hardware, algorithms, and software all built in-house, creating a vertically integrated solution.
- **Predictive, not reactive**: Platform detects changes hours to days before clinical events (e.g., CHF, COPD exacerbation, sepsis, falls).
- **Covered by Medicare**: Reimbursable in skilled nursing facilities, lowering adoption barriers.

## Strategic Focus
- **Proactive senior care**: Continue reducing hospital readmissions and fall risks through early detection.
- **Clinical evidence generation**: Hiring a Senior Scientist for Real-World Evidence and Outcomes to publish rigorous studies proving impact.
- **Scaling clinical services**: Expanding virtual nurse monitoring and telehealth NP roles to support providers.
- **Global expansion**: Already operating in the UK, Pakistan, Germany, and Qatar.

## Why Work Here
- **Culture**: Mission-driven team of engineers, scientists, and physicians focused on transforming senior care. Emphasis on diversity and inclusion. [circadia.health/about](https://circadia.health/about)
- **Work model**: Hybrid – 2-3 days per week in the El Segundo, CA office for most roles.
- **Compensation**: Transparent salary ranges (e.g., Nurse Practitioner $120K–$160K, Senior Scientist $165K–$205K) [linkedin.com](https://www.linkedin.com/company/circadia)
- **Engineering culture**: In-house development of hardware, AI, and software; opportunities to work on cutting-edge radar and machine learning technology.
- **Growth**: Rapidly scaling team (+35.6% YoY) with roles across engineering, clinical, customer success, and data.
