Job description

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 Health Intelligence Team operates within the HealthOS Mission to enable other teams to efficiently deliver personalized solutions that help members build sustainable, empowered relationships with their health. We’re at the forefront of integrating Generative AI and LLMs into the Oura experience, transforming how members interact with and learn from their data. In addition to shipping delightful end-to-end Android features, we build platform foundations: modular, reusable components, shared libraries, and clear APIs/contracts that let other teams plug into HealthOS capabilities quickly and safely. You’ll collaborate closely with product, design, backend, data science, and research while shaping an Android architecture that is scalable, testable, and easy to evolve.

This is an on-site (Helsinki, Oulu) or remote Finland-based role.

This is a senior position.

What you will do:

• Work together with a passionate team of engineers, designers, UX and product managers creating stellar member-facing experiences around AI, that deliver health insights and guidance.
• Own an AI-powered, member-facing feature end-to-end, from early prototyping through production and iteration, including the client-side integration points with backend AI services.

• Develop new features and capabilities using Kotlin and Jetpack Compose, ensuring responsiveness, scalability, and alignment with design guidelines.
• Refactor existing features to improve code quality, performance, and maintainability.
• Ensure high quality through code reviews, automatic testing, and Android engineering best practices.
• Build and evolve shared design-system components and platform foundations reused by other squads.
• Contribute to build tooling, CI performance and engineering practices that raise velocity across the Android codebase.

Requirements

We would love to have you on our team if you have:

• A minimum of 5 years of professional development experience shipping Android apps.
• Deep experience with Kotlin, Jetpack Compose, and modern Android app architectures (e.g., MVVM/MVI), as well as strong fundamentals in Android platform APIs.
• Proven experience building complex user-facing features and reusable UI components.
• Experience with collaborative development on complex shared codebases.
• Proficiency with Git, branching strategies, pull requests, and standard code review workflows.
• Focus on quality with unit, instrumentation, and snapshot/Compose testing; familiarity with CI for mobile.
• Ability to design and implement performant, reusable, maintainable, and testable code.
• Solid understanding of what you build as a whole, both from an engineering and end-user perspective. You like taking end-to-end ownership.
• Strong cross-functional collaboration skills: Able to work effectively with designers, product managers, and other engineers.
• Strong communication skills: Able to articulate technical concepts and decisions clearly, both verbally and in writing.
• Problem-solving mindset and adaptability: Strong analytical and troubleshooting skills.
• Comfortable with change, ambiguity, and learning new technologies or approaches as needed.
• A proactive, get-things-done attitude.

We also appreciate if you have one or more of the following:

• Experience with Kotlin Coroutines, Flow, performance profiling, and app startup optimization.
• Experience with persistence and data layers (e.g., Room, SQLDelight, Proto DataStore).
• Cross-platform experience (e.g., iOS or backend).
• Experience building GenAI/LLM-powered product features, including client integration with an AI or LLM backend.
• Experience building or maintaining a shared design-system or component library / SDK consumed by multiple teams.
• Experience with Android home-screen widgets or other platform-surface integrations.
• Ability to mentor other engineers and increase developer productivity across teams.
• Experience working asynchronously across countries and time zones.
• Experience with health, wellness, or fitness products.

• Understanding of accessibility standards in Android development.
• Experience shipping your own Android apps.
