Staff Data Scientist

Fitbit, US - San Francisco

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)!

Fitbit Research is world-class team of hacker-scientist-types who dream up, prototype, and deliver shipping products. We investigate a big set of problems from hardware development to embedded signal processing algorithms to data mining.  Experimentation is critical.  We work in a dynamic and collaborative environment where the goal is to learn things quickly, iterate fast, and make awesome products.

Your Role:

You will work with a team of data scientists and analysts to invent compelling data products in the Fitbit ecosystem of wearables, connected devices, and software services. Think the ultimate personalized fitness coach that is driven from your data, then combine that with sleep, nutrition, weight, and all the other data in the Fitbit experience. You will have large responsibilities in generating or taking ideas and growing them into a final product. You will help dream up and prototype new data-based features, perform analysis to determine what is interesting and useful in those features, design experiments to focus feature development, and design scalable machine learning. You will do a lot of experiments. You will work with a diverse group of technical experts in the research department to figure out hard problems and, ultimately, help ship products with the other engineering teams at Fitbit.
