About Oura

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 over two million people understand and improve their health by providing daily insights and practical steps to inspire healthy lifestyles.

About the Consumer Backend Team

The Consumer Backend team collaborates with various Oura app feature development squads supporting them with their backend needs. The team owns and maintains backend services that power key features in the Oura app such as the Meals and Glucose features. We’ve recently worked most closely with the Metabolic Health Squad.

About the Metabolic Health Squad

While we started with sleep, over the years, we’ve expanded to include additional health pillars to provide a more complete, holistic picture of your health. Like sleep, activity, cardiovascular health, and stress & resilience, metabolic health is an integral component of health and well-being. Currently this means helping our members track and improve their metabolic health via facilitating glucose tracking through integrations with external Stelio biosensors, capturing nutrition intake data, and delivering actionable insights derived from that information that helps educate and inspire members to healthier metabolic decisions while maintaining a psychologically healthy relationship with food.

Working closely with the Metabolic Health Squad, you’ll help empower Oura members to build metabolically healthy habits that support daily vitality and long-term healthspan.
