We are CalmWave, a fully remote company focused on reducing alarm fatigue in hospital ICUs. CalmWave’s platform captures, analyzes, and synthesizes real-time hospital data (vital signs, labs, medications) to improve patient outcomes, optimize hospital operations, and enhance staff retention. CalmWave takes inspiration from hard-won lessons learned in managing monitoring and alerting signals in Enterprise IT and applies them to healthcare organizations to improve Operations Health and efficiency.


We’re a small team looking to add 1-2 engineers that complement our skills. Our team is responsible for the web application that clinicians use to improve alarm management as well as the back-end system that collects data from hospital bedside monitors (vital signs), integrates with Electronic Health Record (EHR) systems, and interfaces with our data science algorithms.

We use Elixir with Phoenix LiveView, Postgres, Docker, and AWS to build a robust application quickly and collaboratively.
