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 Membership team owns Oura’s end-to-end membership experience: sign-up, trials, renewals, upgrades, cancellations, payments, and access to membership benefits across our channels. As a Full-Stack Engineer, you’ll build the web experiences and cloud services that make Membership reliable and easy to use. You’ll work on customer-facing features that directly influence member experience, retention, and revenue, while helping us operate and improve the systems behind them. AI-assisted development is already part of how we improve engineering effectiveness at Oura. We use AI tools to accelerate exploration, implementation, testing, documentation, and problem-solving, while relying on engineering judgment to validate output and protect quality, security, privacy, and reliability. We’re looking for someone who is already comfortable using these tools and is motivated to explore where they can create further practical impact. You may have deeper experience in either frontend or backend development. We do not expect equal depth across every technology, but we do expect you to be comfortable owning meaningful features across the boundary between user interface, APIs, data, and cloud services. What you’ll do Work with Product, Design, and engineers to understand customer problems, shape solutions, and deliver them at scale. Own vertical slices of the Membership roadmap from technical discovery through implementation, release, and production operation. Build accessible, responsive, and reliable web experiences using TypeScript, React, and modern frontend practices. Design and implement backend services and APIs using Node.js, Express, and related technologies. Work with data models, external integrations, and the failure modes that come with payments, subscriptions, billing, and account access. Create maintainable, testable code and contribute to automated testing at the appropriate levels. Participate in code reviews, technical discussions, and documentation that help the team move quickly without sacrificing quality. Participate in the team’s upkeep rotation, including monitoring, debugging, and resolving production issues. Support safe releases and improve observability, reliability, performance, and product health over time. Collaborate with teams including Finance, Marketing, and SRE. Identify
