At Fitbit, our mission is to help people lead healthier, more active lives by empowering them with data, inspiration and guidance to reach their goals.
We started our journey in 2007—as a team of two with one big idea. Since then, we’ve grown to over 1,500 employees, sold over 60mm devices, and built a health and fitness community across the globe. In fact, the Fitbit Community has taken enough steps to walk from the Sun to Pluto! Offering award-winning products, a top-rated mobile app and an easy-to-use online dashboard, Fitbit provides personalized experiences that help our users reach their goals. With a reenergized focus on innovative devices, interactive experiences, and enterprise health we are transforming the way consumers and businesses see health & fitness.

We offer a competitive benefits package and amazing perks like unlimited snacks, Friday happy hours, onsite workout classes, and a strong focus on a healthy work-life balance. As part of our team, you’ll have the opportunity to grow your career, contribute your ideas to life-changing products and services, and—above all—have fun doing it.
