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.

We’re looking for a Senior Fullstack Engineer to join our growing Software engineering organization in the USA. Our organization consists of cross-functional squads, each with a specific area of ownership across the Oura product. You will be part of the Commerce Mission. The Commerce Mission drives Oura’s product sales revenue through online e-commerce and offline partnerships.

What you’ll do:

• Own end-to-end features in Cart & Checkout, collaborating with Product, Design, Data, and partner engineering teams to define scope, architecture, and rollout plans.
• Design and implement full-stack solutions using technologies like TypeScript, React/Next.js, Tailwind, AWS Lambdas, DynamoDB, Redis, and modern CI/CD workflows.
• Lead technical design for high-impact initiatives in areas such as:
• Global checkout flows (multi-currency, taxation, shipping, localized UX).
• Fraud and risk controls that protect customers and the business.
• Enabling buying pathways in ever-expanding sales channels
• Champion quality and operational excellence:
• Write well-tested, well-documented code.
• Instrument monitoring, logging, and alerting for new features.
• Plan safe rollouts with feature flags, A/B tests, and clear rollback strategies.
• Shepherd work from idea to stable production:
• Drive technical discovery and spike work when requirements are ambiguous.
• Collaborate with QA and SRE to ensure readiness for peak events (launches, BFCM, campaigns).
• Support on-call rotations by helping debug, fix, and prevent incidents in critical revenue paths.
• Raise the bar for the team:
• Mentor other engineers through design reviews, pairing, and thoughtful code review.
• Help standardize patterns, documentation, and best practices as the team and codebase scale

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

• 7+ years of software development experience
• Strong Typescript skills
• Solid knowledge of API best practices, experience with serverless patterns (AWS Lambdas) and Service-Oriented Architectures
• Have designed, built, and deployed scalable, performant web services on AWS
• Have experience with DevOps,
