Cardiogram | Senior Frontend Engineer | San Francisco, CA | ONSITE

Are you a frontend engineer who wants to make the world healthier?

Cardiogram's goal is to shift healthcare from reactive to preventive, starting with the most ubiquitous health sensor deployed today—optical heart rate. Every modern wearable, from the latest Apple Watch to a $29 Xiaomi, ships with a heart rate sensor. Locked within that sensor data are signs of both daily activities like sleep and stress, but also major health conditions—sleep apnea, diabetes, high blood pressure, and atrial fibrillation—that affect more than a billion people globally.

Frontend engineers build the core of the company: the Cardiogram app for Android or iPhone. You'd be working in primarily ReactJS, NodeJS, Javascript/HTML5/CSS3, with the opportunity to learn native iOS (Swift) or Android (Java).
