Senior iOS Engineer

Our mission at ŌURA 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 Android and iOS app developers distributed across the EU and US. All app developers collaborate closely on each platform, regardless of location or specific feature squad. 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.

We are looking for Senior iOS Engineers (minimum 5 years of experience) to join one of our app development teams. There are several roles available covering different feature areas, such as activity and movement, women’s health, or new member onboarding. This is a remote US position 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. Oura employees in other major cities (like Boston and New York) occasionally gather informally at local co-working locations.

What you will do:

• Design, build, and maintain high quality code for projects on the team’s roadmap

• Push projects forward by closely aligning with PMs and Designers

• Collaborate with other teams such as backend, firmware, data science, research, science, or QA to deliver complex mobile app features

• Work with iOS colleagues across the US and EU, to improve the health of the iOS codebase

• Contribute to technical discussions, code reviews, and platform level improvements
