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.

Fitbit is now a publicly traded company creating award-winning products and services that are available across the globe. We’re transforming the way the world sees health & fitness. As part of the Data Platform 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.
