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. Our engineering organization consists of many talented developers distributed across the EU and US.

For day-to-day feature work, our engineers are organized into smaller cross-functional 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.

This is a remote US role with a preference for candidates based in the US-Pacific timezone. We have offices in San Francisco and San Diego for those who prefer hybrid or office settings. We also have employee hubs in New York City, Boston, Los Angeles, Seattle, and more.

We are seeking a highly motivated Senior Backend Engineer to join one of our growing teams. There are several roles available covering different feature areas, from enabling new hardware capabilities and interaction modes to building multimodal data labeling and model training pipelines to drive personalized guidance. This is an opportunity to be part of teams that are at the forefront of wearable technology, innovating and defining the future of Oura’s products.
