Sr. Software Engineer (Communications & Login)

Our healthcare system is the leading cause of personal bankruptcy in the U.S. Every year, over 50 million Americans suffer adverse financial consequences as a result of seeking care, from lower credit scores to garnished wages. The challenge is only getting worse, as high deductible health plans are the fastest growing plan design in the U.S. Cedar’s mission is to leverage data science, smart product design and personalization to make healthcare more affordable and accessible. Today, healthcare providers still engage with its consumers in a “one-size-fits-all” approach; and Cedar is excited to leverage consumer best practices to deliver a superior experience. The Role: Cedar is on a mission to fix the broken patient financial experience in healthcare.

It’s a deceptively complex problem. What we send, when we send it, how it's personalized, and how patients log in to act on it can be the difference between confusion and clarity. Done well, great communication doesn’t just improve payment outcomes—it helps patients feel informed, in control, and supported during a stressful part of the healthcare journey.
