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. The Oura App operates at a massive scale, featuring many distinct ML-powered features that affect millions of active Oura users.

We are looking for a Software Engineer, Core Platform (All Levels), to join our core platform teams. We’re looking for exceptional people. If you lack “senior-level” experience but are otherwise highly capable please do apply.

Staff+ engineers will also be considered. This role relates to the following Core Platform Teams: Algorithm Platform Dataflow Platform We’re looking for great candidates that can work on projects related to one of, or both of these teams. About the Algorithm Platform Oura runs algorithms on the ring, app and cloud, both in real time and as batch models.

The Algorithm Platform team is focused on the systems that run algorithms in the mobile application and cloud. Platform systems for training ML models are outside of the scope of the team. Ensure seamless devX by making it easy to implement, test, validate and release algorithm-heavy features that power the Oura app, including those reliant on ML models.

Ensure algorithm execution is reliable and compute-efficient. About the Dataflow Platform Oura’s main mobile application and backend handles millions of active users and TBs of data. The dataflow squad is responsible for the key abstractions, data stores and syncing protocols that guarantee data moves seamlessly between our mobile application and the AWS cloud.

Empower feature teams to develop end-to-end features without the need to involve backend engineers. Evangelize compliance with standardized data schemas, data quality and data lifetime management. Ensure our systems are performant, scalable and cost-efficient, able to handle millions of active users and PBs of data.

These teams are platform teams and therefore most of the work is internal-facing. Both teams have the same upwards line management and it is possible to work on projects from either of them based on internal need and motivation. The tools created by both teams span both cloud and mobile platforms.

We’re looking for candidates that are willing to work on mobile as well as backend. Current Tech stack iOS: Swift, with some cross-platform C++. Android: Kotlin, with some cross-platform C++.

ML: Pytorch Cloud: AWS, Python, some Rust. If you don’t have mobile development experience, don’t worry! The same fundamentals apply - handling high concurrency, robustness to crashes, ensuring data consistency and implementing high performance code are all fundamental for these teams.

We believe great engineers have a solid understanding of the fundamentals and learn quickly. It is more important that you can showcase excellence than having experience with specific tech.

What We’Re Looking For

: Previous experience solving challenging technical problems. Broad knowledge of software fundamentals, algorithms and data structures, concurrency, databases, testing, system and API design. Ability to take ownership of projects, design technical solutions, drive implementation, and deliver results with limited guidance.

Ability to produce high quality code quickly (with and without AI) - you’re a prolific programmer. Driven by value creation and overall impact. Team player with great spoken and written communication skills.

Motivated to learn and further develop your skills.
