Stay motivated and improve your health by tracking your activity, exercise, food, weight and sleep


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. Today, that idea has become a movement. 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. In fact, the Fitbit Community has taken enough steps to walk from the Sun to Pluto.

Our culture combines the spirit of startup with the perks of being public—offering a competitive benefits package and amazing perks like free lunches, Friday happy hours, on-site fitness classes and more. 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.

Our Shanghai office is located in the Huangpu district, on the bustling Hubin Road. The Grade-A office building is in close proximity to multiple Metro stations, thus offering easy access to the rest of the city. The Xintiandi entertainment district is within walking distance, filled with bars, restaurants and boutique shops. Our local team consists of a wide range of extraordinary talent from Embedded Engineers to Manufacturing & Supply Chain specialists.
