Senior Android Engineer, Core Sensing

Our mission at Oura is to empower every person to own their inner potential. Our award-winning products help our global community gain a deeper knowledge of their readiness, activity, and sleep quality by using their Oura Ring and its connected app. We've helped millions of people understand and improve their health by providing daily insights and practical steps to inspire healthy lifestyles. Empowering the world starts with living our values and empowering our team. As a quickly growing company focused on helping people live healthier and happier lives, we ensure that our team members have what they need to do their best work — both in and out of the office. Oura’s engineering organization consists of talented developers distributed across the EU and US. For day-to-day feature work, our engineers are organized into smaller cross-functional, geolocation-specific feature squads or teams. Our squads have a great deal of autonomy and are responsible for the development and architecture of their features. Squads take full ownership of their code and handle everything from concepting, design and implementation to release, maintenance and bug fixes. Your team, the Core Sensing Squad, is a platform team making sure that the signals collected from the ring are available in the app for other feature teams to build on top of. As such we oversee a large variety of sensing measurements and design complex technical solutions to ensure that the end to end features built on top of them works as intended. In addition to building the plumbing, we also explore new sensing areas that might not yet have another home. We also focus on evaluating and integrating new cutting edge algorithms into our product. We are a small but ambitious team, developing features that are at the edge of what is possible with modern Android phones. If this sounds interesting, come join us!
