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.

Fitbit’s HQ campus is made up of three modern buildings located at the heart of SOMA in San Francisco. Monday-Friday you can feast your eyes on amazing views of the skyline, then feast yourself on some of the city’s best food trucks, lunch spots and coffee shops. When you’ve had your fill, lace up and make your way to the Ferry Building for the perfect post-work run or walk along the water (with the Bay Bridge as your backdrop)!
