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. Since then, we’ve grown to over 1,500 employees, sold over 60mm devices, and built a health and fitness community across the globe.  In fact, the Fitbit Community has taken enough steps to walk from the Sun to Pluto!  Offering award-winning products, a top-rated mobile app and an easy-to-use online dashboard, Fitbit provides personalized experiences that help our users reach their goals. With a reenergized focus on innovative devices, interactive experiences, and enterprise health we are transforming the way consumers and businesses see health & fitness.

We offer a competitive benefits package and amazing perks like unlimited snacks, Friday happy hours, onsite workout classes, and a strong focus on a healthy work-life balance. 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.

The role:

Our mobile clients are key component of this user experience, they connect the data in our wireless sensor devices to our cloud based data storage backend while also giving users the tools to track their progress, set goals and compete with friends.  We are looking for an iOS engineer who is excited to tackle many interesting problems we are actively working on which includes:

  • Creating engaging yet computationally efficient interactive data visualizations that are optimized for mobile devices with touch screens. This is an area of user interfaces for which there is no established solution; we aim to set the standard. 
  • Overcoming the hurdles of distributed systems to build native mobile clients that are tolerant of transient connectivity. We aim for our mobile clients and sensor devices to function together as normally as possible even when there is no connection to the internet. 
  • Exploiting low power communication technologies to make the internet of things a reality. We have been on leading edge of consumer deployment for both wearable sensors and Bluetooth Low Energy. 
  • Crafting beautiful mobile user experiences that allow users to intuitively accomplish any task. Our mobile clients are a vital part of the user interface to the Fitbit platform.
