Senior Fullstack Engineer, Commerce Mission

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, including CI/CD pipeline configuration, monitoring and observability for code in production, and crafting quality alerts to support operational excellence.
• Have a pragmatic, entrepreneurial attitude and delivery-focused mindset: you can handle tradeoffs between short-term goals and long-term tech debt
• Deep expertise in either:

• Frontend: modern React/Next.js, TypeScript, modern CSS (e.g., Tailwind), web performance, accessibility, and frontend testing (Jest, Playwright); or
• Backend: designing and operating web services on cloud platforms (preferably AWS) with strong API design, data modeling, and observability practices

Nice to haves (at least one):

• Experience with online payments, PSPs, digital wallets, 3DS, or fraud/risk systems.
• Experience with global commerce (multi-currency, localization, tax/shipping rules, regional content).
• Experience building and maintaining design systems, shared component libraries, and/or experimentation frameworks (feature flags, A/B tests).
• Prior work on event-driven or serverless architectures at scale
