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 advantages of being public, offering a competitive benefits package and amazing perks. 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.

In our newest Fitbit office in Bucharest, located in the heart of the city, we are planning to build on the foundation laid by the Vector Watch team. We are looking to keep growing and this role will be fundamental to the continued success of Fitbit as we build exciting new products and services.
